Your Case Is In Good Hands
My lawyer saved my driving record. She told me relax she will handle it and she kept her word I got off and beat all my charges.. I would refer her to anyone in need of a great [lawyer].
Sei Arii represented me in a 2nd DUI case. The charges were pending possible jail time. Ms. Arii did her homework before the court date and was able to represent me well. I walked away with probation and my life. Thank you for your assistance and I would recommend your services to anyone. You are an excellent attorney.
Very knowledgeable, professional and an attorney who fights to the end for you and your well being Highly recommend her for any services that you would need legally
Ms. Arii is [very] skilled a knowledgable lawyer who worked a miracle in my case. I was facing a year in jail, but she was able to make the state prosecutor case look very weak, and was able to convince the judge there was no merit to her argument. When you talk to Ms. Arii you can tell she is on your side and will do all it takes to get you a favorable result. She is well worth the money spent and the peace of mind knowing your lawyer went all out for you.
I am beyond blessed to have found Sei-Hee online. This has been the best couple thousand I’ve ever spent. A great investment in my future as well and totally worth it. She was thorough, and explained in detail the complexities of my case. Through her council and expertise, she was able to get all of my DUI/DWI charges dropped. She is worth every single penny and I would highly recommend her. If you are still searching, don’t second guess it. She’s the real deal. Highly professional and very responsive as well. Court is a very unpleasant experience but I was truly pleased with her commitment and the resolution to my case.
Attorney Sei-Hee was the first to respond to my request for a lawyer. We set up a consultation, where she took her time and explained to me exactly what would and could happen. The feeling that i got from her was very comfortable. She set me up with a payment plan and was very understanding of everything. I was facing a dui dwi and two tickets all in this case. Attorney Sei-Hee did what she does [resulting] in me only paying one ticket. I hope to never need a lawyer again but if I do, she will be representing me again no thoughts about it.
I was faced with a legal situation (DUI) this summer and immediately turned to Google. After many searches for the Montgomery County area, Sei-Hee’s name kept popping up. I called her and after our initial phone conversation, I knew that she was the lawyer I wanted to hire. She made the process smooth and made sure that I understood all of my responsibility on my end. It was important to me to know what all I could be doing towards my case as far as which classes to take and how to proceed with my 90 day driving suspension.
When it came time for my court date, she eased my nerves talking me through the process and what to expect. When I met her in the courtroom that morning I was immediately eased with her knowledge of the proceedings. I personally had a favorable outcome that was not anticipated. Sei-Hee did a fantastic job in preparing me for all outcomes because you truly don’t know what to expect prior to the courtroom. Regardless of what outcome I would have received that day, Sei-Hee was by my side and made me understand everything. I highly recommend her based on her skill, knowledge, and personal skills.
I was lucky enough to have Sei-Hee by my side when it really mattered. Her analytical and interpersonal skills are above par and she’s more than willing to put in the time it takes to get your matter resolved. I highly recommend Sei-Hee.
She was very professional, very helpful, explained everything with detail, very patient and, responded within a reasonable amount of time. I was also very happy with the outcome of my case.
I wanted to thank you for your professional assistance. But also, for making this difficult experience, more tolerable. You project a calming confidence. Your thorough approach, are both reassuring and make the process understandable. Something I found very useful. I could not be happier with the outcome. I found your fee schedule, very reasonable and straight forward. Your guidance, and direction, as to steps that would assist my case were invaluable!
Not only she kept me out of jail but her advice during and after my case helps me to put my life back on track. Her deep professionalism and skill is so amazing. The way she [prepared] me for my case with a constant follow up and consultation was wonderful and final presentation during my court date was [unbelievably awesome]. Thank you C.Sei-Hee
She was very professional and had a good demeanor during the entire process. She is in good standing with the public servants and courtroom professionals. I’m glad I used her and was pleased with the outcome of my case. I would certainly use her again if needed.
C. Sei-Hee Arii was able to get a favorable outcome for my case. She was very helpful and knowledgeable about the issues involved.
Due to my own procrastination, I reached out to C. Sie-Hee Arii on a wednesday when my court appearance was that monday. I was arrested for a dui (.15 bac) and about 7 consequent charges which added up to almost $2k in fines. Immediately I felt as if I was putting my case into the proper hands. After going through my original arrest paperwork she found mistakes made by the officer which would help our case. Ultimately all charges we dropped and are going to be expunged. This is better than best case scenario in my opinion and I feel extremely lucky/blessed to find a great attorney at a affordable rate.
Hiring C. Sei-Hee Arii as my DUI/DWI lawyer was one decision I do not regret. She used her extensive knowledge of the law and being very resourceful to get me out of a sticky situation and I genuinely feel like she was fighting for me in court. She has very competitive rates and in additional to handling the district court hearings she also coaches you on the MVA administrative hearing and she does all this in a way that makes you feel comfortable and not doubt hiring her. She got all my charges dropped at the end of the day and I am forever going to be thankful for her diligent work.
Miss Arii was very helpful with my court case, saving me astronomical amounts of money. She knew how to handle the situation with proficiency and great professionalism.
I was charged with DUI, DUI per se, DWI, and failure to control vehicle speed on highway to avoid collision. Sei-Hee found holes in my case and was willing to fight it but I just wanted to get it over with. On the day of trial, Sei-Hee was able to get me the best outcome out of everyone else in court facing similar charges, unsupervised PBJ for the DWI and the rest of the charges dropped. She is very professional and candid which is why I chose her over other attorneys. Highly recommended.
Sei-hee was my lawyer for two separate incidents and won both. She’s a very knowledgeable, resourceful, patient, and an awesome person. She answered my questions in a timely manner, and guided me through what I needed to do. I highly recommend her and I was extremely lucky to have found her.
Sei-Hee truly understood my case and was very kind. What struck me the most was that she always answered my questions, represented me and made sure that my case was presented fairly. She was upfront and honest about her approach and what could be expected and tried her best to represent me. In my case, she went out of her way to get the most favorable judgement and I cannot be more happy than that. If you run into any criminal related issues and would want to use a lawyer I strongly recommend Sei-Hee, she is professional, smart and wants the best for her clients.
C. Sei-Hee Arii was truly a godsend. I was facing my second DUI in 9 years. As a single mom, my panic was off the charts. Sei-Hee was a rock during the storm. She had a plan and she gave it to me straight. Yes, I was facing jail time but because of a combination of Ms. Arii’s expert legal knowledge and direction I never saw the inside of a cell. Trust me, she’s who to turn to and she cares. Don’t get me wrong, a lot of work went in to giving her something to go on but if you’re willing to fight, so is she. In a desperate situation I was given hope and a future. Thank you Sei-Hee.
I was facing jail time, loss of my drivers license, a police record (that would have dogged me for the rest of my life), loss of my job/career, retirement and benefits and maybe even my home. You took care of everything! You are the greatest and I can’t thank you enough for all that you did for me. If by chance I ever get myself in another mess I promise you will be the first person I call.
I sought the services of Attorney Sei-Hee Arii to handle my DUI case. From the outset she displayed exceptional professionalism. She was always prompt in responding to my calls and emails and took time to explain legal terms and processes in a way that I could understand. Her clear communication helped stay informed and at ease throughout the process. She demonstrated a deep understanding of the legal nuances and offered strategic advice on various aspects of my case. Thanks to Sei-Hee’s efforts , the outcome of my case was the best case scenario, you can imagine. I believe the quality of service justified the cost. I am extremely grateful and my experience with Sei-Hee was very positive. Based on my experience, I would highly recommend Attorney Arii services. Her Expertise and dedication to her clients make her an excellent choice.
Sei-Hee is an excellent lawyer who is second to none. She handled my case in a professional manner. She told me what to expect and assured me of her help with my traffic violation related charges. She was very brief and clear when she represented me during my court hearing. She presented the case to the judge in a clear manner and convinced the judge that charges me does not deserve a harsh punishment and that I should be given a second chance to prove that I am a good law abiding person. The judge accepted her argument and I got out of trouble. Therefore I highly recommend her for any traffic related violations because she has what it takes to get you out of trouble once you follow her Counsel before court hearing. She also understands circumstances and gives good recommendations. You will never regret her services.
Ms. Arii was extremely personable and professional. Whenever I contacted her, [the] response was timely. Her confidence made me satisfied that we’d win, and we did.
[Sei-Hee Arii] showed that she cared not only professionally but she cared about my wife as a person…
[Sei-Hee Arii] always responded to my request and gave competitive prices for her work. In the courtroom, she clearly had done her homework and won the case.
I chose Sei-Hee Arii as my lawyer and am so glad I did. I went through an unfortunate set of events and had no idea what to do or where to go. She was the only one that made me feel better, safe, secure, and comfortable throughout the whole process, especially with this being a first and only time event for me. She is very knowledgeable with the process, people, judges, and court systems to get the best results and has done so for me. Especially reasonable given everything she has done and I express my utmost gratitude for her. I can recommend her for whatever problem you are going through, she is 110% worth the phone call. Sei-Hee Arii is the best and correct choice to go with.
I had a DUI and my job was depending on the charges. After all was said and done all the charges were dropped. Sei-Hee is great at what she does. I highly recommend her if you want great results
[Sei-Hee Arii] is worth every single penny and I would highly recommend her.
C. Sei-Hee Arii took a chance taking my case the weekend before my court date. Not only did she treat my case like she had months to prepare, she was also very graceful as she spoke with the states attorney. She courteously explained everything that was happening very promptly so I was completely sure of any decisions I would have to make. All in all I was more than please with the great care Ms. Arii took of me and my case. I would recommend her 11 out of 10 times!
I enlisted the services of Ms. Arii when I got slapped with 7 tickets – 1 being a DUI. Ms. Arii was very responsive and helpful during the whole process. When it came to my court date, she successfully convinced the prosecutor to strike a plea bargain. My 7 tickets were dismissed and I ended up with a PBJ for reckless driving. I am in the process of expunging that from my records. I am very pleased with the outcome and am thankful to Ms. Arii for helping me move on from this.
My experience with this firm was amazing! C. Sei-Hee Arii was very professional, at the same time easing my anxiety about the case. I would highly recommend using this law firm. You will feel confident knowing the lawyer representing you cares about your case and will do everything possible to get you the best result.
Sei-Hee was very effective at putting our minds at ease. She told me to stop worrying and let her handle my wife’s case. She was responsive and quickly resolved an issue when my wife’s license was inadvertently suspended. She is the consummate professional. She showed that she cared not only professionally but, she cared about my wife as a person who made a mistake. Hiring her was the best decision we could’ve made.
I was charged with a DUI and several related offenses, after speaking with C.Sei-Hee Arii–I knew within 20 seconds she was the best of the best. She is with you every single step of the way from paperwork to trial. I was 25 and had no idea what the legal system was like, Ms. Arii explained what to do, where to go, and how to best address your case. She explained to me my options and everything worked out just as she promised.
In a nightmare situation, Sei-Hee helped me not only legally but also psychologically; I’d contacted other lawyers before finding her, and I can honestly say she was the only one that seemed to actually pay attention to my personal, specific situation, offering advice that suited my exact situation – very much unlike the other lawyers I’d contacted (it’s worth mentioning that my initial consultation over the phone was with Sei-Hee herself, not an assistant that couldn’t care less like the others I’d contacted).
Sei-Hee was professional, made communication extremely easy, and took time to address a related issue/question that popped up. In such a stressful time, she really did put my mind at ease while being straightforward and honest. The outcome at court was best case scenario – a result due to her ability to present my case (and me as a decent citizen) convincingly. I highly recommend Sei-Hee Arii as a knowledgeable, dependable, and successful attorney.
I was charged with a DUI in late 2014. I’ve never had any run-ins with the law before and didn’t know where to even start looking for a lawyer to handle my case. I talked to a number of DUI lawyers and ended up choosing Sei-Hee, a decision I’m so glad I made. I wanted Sei-Hee to represent me because she showed genuine interest in my case, whereas I felt like “just another routine DUI case” when I reached out to other lawyers and firms. Sei-Hee is a very understanding person, super responsive, and knows the MoCo court system well. She kept me informed throughout the process and was very helpful in accommodating my schedule and the fact I reside and work in NYC. Additionally, she did her due diligence to look beyond the just the surface of what happened to get the full story. I would highly recommend her to anyone looking for an excellent DUI lawyer in MoCo.
Sei-Hee Arii took care of things right from the start. I didn’t have to worry much about anything as she answered my paranoid questions quickly and efficiently. Told me what’s at sake and what my options are so I could make an informed decision. She was able to work her magic and reduce my DUI to a DWI which is the lesser of the two. I’m happy with my outcome.
First time DUI in Maryland, had no idea what to expect. I called Sei-Hee the next morning and she was immediately kind, understanding, and knowledgeable about the entire process – something I really needed after the traumatic arrest night. I was charged [redacted] for representation in the criminal case. I’m not sure how this compares to other lawyers as she’s the first one I’ve used. There’s payment plans if needed. The MVA case is separate and she prepares you well for you to do it on your own – it’s fairly straightforward and I had no issues getting a restricted license.
There’s an extra charge for her to be there during the MVA case if you feel you need it. I was well over the legal limit, but Sei-Hee negotiated my DUI down to a DWI. I also got a PBJ by following her instructions on what to do before court. It was also clear she was the most knowledgeable/experienced attorney in the court room. I would definitely recommend her to my friends/family or, god forbid, hire her again for myself if needed.
Ms. Arii has been very helpful walking me through all legal processes/steps for an accident DWI. She made time to help go over all the notices and made suggestions for me to do in order to have the best result. In the end I was able to receive a PBJ with unsupervised probation. I was so thankful to have someone I could call and discuss everything with and would take the time to listen to my concerns. Also being much more affordable than some other attorneys that I shopped around for.
Sei-Hee Arii was an excellent lawyer for my husband and me. She was a tremendous advocate for us throughout the ordeal. Sei-Hee did everything previously retained counsel was too lazy to do and handled our case with sincerity, toughness, and diligence.
I am a old man that doesn’t know the law so good. My first time in a court room I was scared. I tried to understand them !! But I could not. Again I was very scared. I call Sei Hee Arii a lawyer who help me with this problem. She was very concerned about my problem understanding the law. She was very patient with me. She is the best at her job. Mis Sei Hee makes anybody fill safe and understanding that every thing will be alright. This a gift from God. And I thank God very day. So to everyone please don’t hesitate to call Mis G. Sei-Hee Arii ( law Firm) to help you in your time of need. Again thank you very much.
I hired Sei-Hee to handle two cases for me. One in Virginia and one in Maryland. Both times, I felt comfortable knowing that I’m dealing with an attorney with a strong background in criminal defense. Throughout the whole process she was clear, honest, and available to be reached anytime. She constantly followed up with me to make sure she had all the facts to represent my cases. This was the peace of mind knowing that I could rely on Sei-Hee. The end result was a favorable judgement. I would highly recommend Sei-Hee for anyone in need of a criminal defense attorney.
I contacted Sei-Hee a week before my hearing, I was worried and didn’t know what was going to happen, I was facing multiple citations, at least 10 including a DUI as well as A DWI. She spoke with me and after our initial consultation I felt so much better, she explained what my next steps should be leading up to my trail date, and ended up getting all my charges dropped, all 10!! But beyond being an great lawyer, she is a caring person who I believe generally cares about her clients and not just there money. If I ever needed a lawyer again, (God forgive), Sei-Hee would be my first choice.
I have been represented by Sei-Hee twice now, and both times she has succeeded in getting favorable results, even to the point of dismissal. I contacted her office whenever I needed her assistance and they were very helpful if she was busy or on vacation, so I would just text her and she would respond and tell me exactly what to do and answers all of my questions promptly. Both times, I did not have to worry about anything leading up to the cases, I would simply just show up and let her do the work which she always does in a very professional manner, and knows exactly what to say in every scenario or questioning being given. I really recommend Sei-Hee because she is just very knowledgeable and kind hearted down to talking with you or the judge and just knows exactly how everything will be played out even before it happens. Thank you so much!
My husband’s case was pretty difficult with his BAC 0.15 and poor field sobriety test results. Besides he was driving on a wrong way by the time he was caught. His driver license was suspended and taken by the police officer immediately. We were very nervous and needed a strong lawyer. Attorney C. Sei-Hee Arii came up from our online searches and she thoroughly explained and educated us with all kinds of circumstances first. She not only was able to get my husband license back shortly after but also dropped DUI/DWI charges. My husband only paid fines with 1 point of traffic violation. Her professionalism, dedication and passion of caring her clients are above and beyond. I would highly recommend her to anyone who needs a strong and intelligent lawyer.
Hiring Sei-Hee could be the difference between your case getting dismissed or not. That was my experience. In my DUI case I mentioned early on that the officer was using dash cam and asked that we recover the footage. Sei-Hee requested the footage and when my court date came, we hadn’t received anything. She made sure that the judge set a deadline for when the prosecution had to present that information and then filed immediately for the case to be dismissed the very next day after the footage wasn’t delivered.
On my next court date, the (different) judge dismissed my case in it’s entirely. If I would have had an attorney who didn’t make a point to get the other side to commit to a date or didn’t follow up immediately to file the paperwork when it didn’t arrive, I would probably have had a different outcome. Sei-Hee knows what she’s doing and will do what it takes to win the case. Follow her instructions exactly and you’re in good hands.
[Sei-Hee Arii’s] not all talk, this attorney takes action.
I contacted Sei Hee Arii regarding my first DUI do to the review I read here, and I’m glad I did. I was nervous because my BAC was 0.15 which is right at the threshold of a more serious charge. She was able to help talk me through the process of what I needed to do as soon as possible, and attend the appropriate classes. This helped reduce my sentence from supervised PBJ to unsupervised PBJ. She was also able to talk to the counseling center and reduce the time I needed to be there (typically 26 weeks). I would definitely hire her again.
I had DUI & DWI charges against me, but I was innocent. Sei-Hee is someone who always believed in my innocence. She spent as much time as I wanted, answering all my questions, explaining her exact defense strategy, and coaching me for trial. Additionally, she spent hours studying my case, honing her strategy, and attempting to convince the prosecutors that I was in fact really innocent. In the end, Sei-Hee was able to spin her magic and got the prosecution to essentially drop all charges. I would highly recommend Sei-Hee because she will a) believe in you b) be dedicated to getting you the best outcome c) be extremely patient and d) apply her magnificent knowledge and talent to the case.
Was really clear about our case and the process and our options. On the day of our court trial we took her advice and was patient and waited and like she said it would all go it did thanks to her professionality and experience our case was dismissed. Would definitely recommend her to everyone.
Sei-Hee is an amazing lawyer that helped me get through a very difficult situation (2nd DUI offense). She provided expert advice and gave me the tools I needed to help mitigate my legal situation. I would definitely recommend hiring her!!
I was facing some jail time and she was able to get everything dropped with me only having to pay one minor traffic citation. Great job! Thanks again!
Ms. Arii was my defense lawyer for two charges and successfully got them both dropped being on probation it was an awesome feeling to find out these charges were dropped. Thanks again Sei-Hee.
I can confidently say that Ms. Arii met or exceeded every high expectation that I had.
Amidst an ugly divorce and custody battle, I made two very selfish and bad choices and needed the services of Sei-Hee Arii in 2016. I have worked with private equity, contract, employment, IP, compliance attorneys in past and had no experience with criminal traffic offenses. Words fail to describe how effective, respected by the judges AND caring Sei-Hee is. I enthusiastically and HIGHLY recommend her to anyone in trouble with the law. See is thorough, no nonsense with prosecutors. And she actually cares about you and your case. From the two trials, 2016-2017, she saw that I got fair treatment and she achieve ideal outcomes for me and my family. I HIGHLY recommend her to anyone in a bind with the law.
Ms. Sei-Hee Arii was personable and took care to learn about my situation. She was helpful from the initial consultation all the way to the end of the case. She made me aware of the worst case scenarios as well as best case scenarios. She helped me to be prepared for my court date and let me know what I needed to do to achieve a favorable verdict. Fortunately, with a little patience we were able to score the most desirable outcome. Overall, she is well informed in the law and also with the court system (judges, prosecutors etc) in Maryland which proved be beneficial in my case. She was also helpful after the court date in making sure that I was able to follow through on getting certain charges stricken from my record. I would strongly recommend giving her a call!
She really cares about her clients and really was helpful… she answered all my questions and really pushes for the best possible outcome for her clients… she was able to get my charges dropped in a final protective order that could have gone either way thanks SEI-HEE
• HER REPRESENTATION GAVE ME PEACE OF MIND • C. Sei-Hee Arii represented me in a difficult traffic appeal case with the outcome winning my appeal. Very thorough and professional throughout the course of my appeal, she was able to negotiate with the Judge and the States Attorney in way that presented the facts in their true merit. I have no reservations in recommending C. Sei-Hee Arii to anyone who may need a great attorney and will definitely hire her for any legal matters I may have in the future. In my experience there is no more professional, comforting and successful Attorney in the DMV.

Sei-Hee Arii will work hard for you. I was very overwhelmed with my DUI/DWI charges against me. I didn’t know where to start, I never been in trouble with the law before, but the stacks were against me. When you get charges like I did, you will get a ton of mail from law offices. I went to three lawyers, my case was hard to prove, and I felt all three couldn’t represent me the way I needed them to. Again, I was very overwhelmed, so I started to look online to do my own research. I came across Sei-Hee Arii’s page. I read her profile and reviews, and I was impressed. My case was tricky, and I was apprehensive about calling, thinking I may run into the same type of lawyer. Boy was I wrong! When I got the nerve to call, she was actually in the office and I was immediately transferred to her. Sei-Hee asked me to explain my case, and I did. I was soo upset about what happened, I couldn’t even explain my whole story without crying. She had a way of calming my nerves over the phone and ask me to come in to consult with her. I did.
When I arrived, I didn’t have to wait long, the receptionist was polite and the office environment wasn’t cold. When I met Sei-Hee Arii in person, she was polite and professional. Her wall displays her achievements and honors, I was impressed. We spoke about my incident and she said something to me at the end that changed everything…that she believed me! Yes, she was willing to take on my case despite the odds against me! Sei-Hee didn’t want me to take the guilty plea. She had my best interest in mind. Yes, she will fight for the underdog! She fought for me and my legal rights. We was in and out of court for almost a year, or very close to a year. That’s how long it took and how hard she fought. Even outside the courtrooms, she never stopped working. She was always consistent with following up my case.
Thanks to her determination and because she is a very good lawyer, my charges was reduced! No DUI/DWI record! Like I said before, the stacks where high against me. My livelihood was in jeopardy. If those charges stuck, I would have been in a very bad place. She proved my case and now I have my life back! I wouldn’t want anyone else to represent me but her! Sei-Hee loves what she does and it shows! If anyone needs a good, no GREAT LAWYER! Please, please contact her! You will not regret it! I can go on and on about Sei-Hee!!! I just want to say Thank You Sei-Hee for believing in me and fighting my case to the very end!!!
My case was complicated involving out of state license. She worked with me in very polite and responsive manner, listened to what were my concerns with my case and came to a conclusion together. Every penny I spent was worth it.
Sei-Hee was a tremendous attorney throughout my entire process. I was charged with a DWI and and DUI in Rockville, MD. From our first meeting, Sei-Hee was a careful and strategic attorney. She provided me with exceptional counsel that allowed me to prepare myself not only for the trial, but also the MVA hearing. As a result of her expert counsel, I was able to win my MVA case and prove to the judge that I indeed made a legitimate attempt to provide my blood alcohol content. Her expertise also allowed me to obtain 6 months of unsupervised probation before judgment. As a result of a continuance which was granted to the prosecutor due to the police officer not being available for the first trial, this journey for me lasted 10 months. Throughout this long process, Sei-Hee was phenomenal in keeping me calm and on track. I would highly recommend her to anyone who is looking for an honest and skilled lawyer. You can’t get much better than her.
This was my first time in any kind of situation involving me going to court. Sei-Hee was able to put me at ease about the whole thing. She is knowledge, aggressive, timely, and responsive. I really appreciate hard work and dedication. She was able to get my case dismiss and I’m extremely grateful. I would recommend her to anyone.
Ms. Arii very knowledgeable in my case. Ms. Arii help me through the court process and got me at ease with the court procedures.
I was charged a DUI/DWI on a first offense and it has been one of the most nerve wrecking event in my life. I soon went online to find an attorney where I found Arii Law Firm. I reached out during off office hours and left a message, she called me back very shortly and gave me some advice and pointers as for my next steps to face the charges. That made me feel calm, more than I had in days. Whenever I had doubts or questions, she was always available and always had the answers I needed. On the court date, she told me what she thought we should do, who we were facing and told me what could be the possible outcomes.
I gave her my full confidence and received a very positive outcome. More than I was really expecting. I was really happy with her service, the way she studied the case and was ready for court. In one of the counseling I did before the court date, they told me I made a great choice with Arii Law Firm and I would say the same to anyone who chooses her. I recommend her 100% to anyone facing a similar situation.
[Sei-Hee Arii] was very professional, very helpful, explained everything with detail, very patient and responded within a reasonable amount of time.
Sei-Hee was extremely helpful, meticulous, and effective. Moreover, her ability to sympathize and relate specifically to our situation was very much appreciated. Even in the initial consultation, she asked very thoughtful questions that no other lawyer thought to ask us, which is how we ended up choosing her as our lawyer.
I received a DUI and reached out to two DUI [attorneys]. Attorney #1 simply told me to take the ticket to the DMV, get your restrictive license and contact a breathalyzer company to get one installed, in your vehicle. So, by the time we get to court we will be ahead of the game. Then I reach out to Arii Law Firm (Sei-Hee Arii), She asked me about the event leading up to the DUI Tickets. She simply said “Don’t worry about it, I will do my best to win your case”, so I hired her.
We went to DMV court and the outcome was a dismissal, no breathalyzer on the vehicle. For me, the scariest part of my ordeal was going to Upper Marlboro seeing the arresting officers in court. On that day, you could not have told me, an hour later, I would walked out the courtroom charges dismissed. Thank you, Arii Law Firm, for your high-quality defense in my case. To potential Clients of Arii Law Firm: If [you’re] pissed off about the ticket, go with Sei-Hee and avoid Attorney #1.
Sei-Hee Arii is definitely an expert in her field. Her knowledge, expertise and professionalism saved my life. She was successful in obtaining a reduction of my charges from DUI to DWI. More importantly, she was successful in avoiding incarceration and convincing the prosecutor to change his recommendation against jail! In the courtroom, it was clear to me that folks were not prepared or represented nearly as well as I was. I felt terrible as I watched someone being handcuffed and taken away. Too bad Sei-Hee wasn’t his lawyer. I was blessed to have found Sei-Hee. I am so happy with the resolution and especially grateful that I placed my trust in her throughout the process. If a friend or family member ever needed legal advice I would definitely refer them to her. Sei-Hee is top notch!
I cannot recommend hiring Sei-Hee Arii as your attorney highly enough. She demonstrated excellent communication throughout my DUI case, ensuring I was always informed and prepared. She provided clear and effective steps to achieve the best possible outcome on my court date, which happened. Her straightforward and transparent approach made the entire process much less stressful. Without her, my outcome wouldn’t have been nearly as good. If you need a dedicated and knowledgeable attorney, she is the one to trust.
I chose Ms. Arii based on reviews I found online and a hunch I had that she would be a great lawyer. I was not let down in any way – infact, I was impressed with Ms. Arii’s passion to serve and serve well. Ms. Arii displayed excellent morals and provided a support that rivaled my own family, all while defending my rights and explaining the law every step of the way. I always felt comfortable and well represented with Sei-Hee as my lawyer. She made herself available to my needs and concerns any time of the day, always communicating within a timely manner. I would [recommend], and have recommended, Sei-Hee Arii to everyone in need of representation. Thank you Sei-Hee! Your representation provided me a second chance in life. Your council provided me a much needed support.
I had a pending DWI and was moving out of state. I was worry for the outcome of the trial. But Sei-Hee [Arii] explain to me what to do. When the trial date came I was glad of the result. I am very glad I choose Sei-Hee as my lawyer.
Sei-Hee Arii took care of things right from the start. I didn’t have to worry much about anything…
I hired Mrs Arii to defend me in my second offense of dwi this morning we show to the court and I can believe what happened my case was dismissed, she gave to me advices and told to do some counseling community service aa meetings and I completed all that, to now I can believe the results. No probation, no fines, nothing. I’m very happy and recommend Mrs. ARII AS YOUR LAWYER SHE’S IS THE BEST
She is awesome she beat my case which was a DUI/DWI in Virginia I’m very happy that she knows her stuff wow thank you so [very] much!!
I can say it was the best decision to seek Ms Arii’s assistance. This was my first DUI and the ordeal was really nerve-racking as I felt my life was over after the arrest. She explained to me very well what could possibly happen and I was kept informed and never felt I was given the run around like the first attorneys I called. She was very professional and very knowledgeable when it comes to DUI. I would definitely refer her to my family and friends. Thanks!
Arii was very friendly and helpful. She looked into the case very keenly and provided multiple options. She did a great and commendable job in my case.
I was referred to Attorney Arii by a co-worker of mine. He informed me of her great work and I was able to experience it myself. Attorney Arii really works with her clients and has their best interest at heart. Her word is honest and keeps her clients informed throughout the entire process. I never needed a lawyer until recently but I am glad I used Attorney Arii.
Although anonymous, I am not ashamed to say that I am a high school student. I was arrested on New Year’s Day, with a .08 BAC. I was given 4 tickets due to my DUI situation. My life was spiraling downwards because of the stupid decision I made, and I continued to agonize over the burden I placed on myself and my whole family until I met Ms. Sei Hee. She was an outstanding lawyer, speaking to me and my mother, what to expect, what to do and what not to do. She gave us as much information as she could possibly provide regarding my case, and the potential consequences I may face in court.
Because of her, we took proactive steps as my court date approached, and a week or so beforehand, she gave me a call, telling me that they decided to DISMISS my case!!! I was overjoyed at this news, being ever so grateful to her. Today, I live my life learning an important lesson early in my life, and I am VERY thankful to Ms. Sei Hee for not just helping me out with my situation, but also for guiding me and my parents, reassuring us that everything would be ok.
Sei-Hee is extremely competent and is willing to work with you.
In Court today, C. Sei-Hee Arii was successful in obtaining unsupervised probation before judgment for the reduced charge of Driving While Impaired by Alcohol despite my breath test result being more than 2x the legal limit exactly 0.20.
Ms. Sei-Hee Arii recently represented me for a DUI case in which I was very pleased with the outcome. During consultation she was very honest with me about my possible consequences, from worst to best, with it being my 2nd alcohol related offense. She advised me on programs to attend before my court date that could lead to a more favorable sentencing in front of the judge. She represented me professionally and positively in the court room and was able to get me a very favorable outcome in comparison to the possible consequences. She did not stop there as she also helped to reduce the traffic citations that came with the DUI when she did not have to. Not only that, but was very reasonable and understanding as far as making payments for her hiring. It was clear that Ms. Arii wants the best for her clients. I highly recommend her as an attorney and thankful for her representation.
I had a dui conviction in another state 11 months ago. My hearing papers were mailed to my old address. My license was suspended. Ari was able to get my license reinstated until my hearing as well as get me a new hearing date. This saved my job. In the end I was given a restricted license. She is one of the best and will fight for you, and 95% of the time gets the most lenient disposition. She was worth every penny. I strongly would prefer as the lawyer to see and retain. Thanks again!
When I contacted Sei-Hee for my second DWI, I felt certain that jail time was in my future. I was scared of spending time there and of how a second conviction could impact my career. Sei-Hee’s knowledgeable approach and personable demeanor allowed me a shockingly positive resolution – the charges were dropped and she helped me immediately file for expungement upon completion of trial. Her prices were fair and she fights for her clients more than the standard DUI lawyer.
[Sei-Hee Arii] is knowledgeable, aggressive, timely, and responsive. I really appreciate hard work and dedication.
She gave me great help for my case. She knows how to get the best result. I just followed what she told me to do, and it comes out with the unexpectedly good result. I strongly recommend her.
Very positive experience from day 1. She is very clear, direct, and supportive. I felt like she provided me with great support with every step of my situation and always responsive when needed. 10/10 recommend!
It was the day before thanksgiving and I was on my way home from a friend’s high school reunion and I get pulled over and blow a 0.18, well above the legal limit. Shortly after being released I found Ms. Arii through some online researching. She was very understanding and helped ease my anxiety. Her pricing was also not astronomical as other firms were trying to charge me. Luckily I recorded my altercation on my phone and Ms. Arii did a thorough job in comparing my recording to what the police officer wrote on his report and developed a defense, even if it was a weak one. I felt she was doing everything she could for me to beat this. Long story short, I received the least severe charge, got a PBJ (this did not go on my record as having received a DUI) and 6 months probation.
When I got my 1st DUI, I was worried. I did not know what to expect since I never got into the wrong side of the law. I knew I had to get a good lawyer to help me fight it in court. I decided to call Sei-Hee Arii and she gave me an appointment to go to her office. I saw down and she took notes while she was asking questions and explaining the whole process. This itself made me calmed and relaxed knowing she will do whatever it takes to fight on my behalf in court. She understood I was a student and gave me a great deal! To make a long story short, i did everything she asked me to do and she was able to convince the Judge to reduce my charges to DWI and best of all, my record was cleared! The money I spent was worth it. If [you’re] looking for the best DUI lawyer in Maryland then call Sei-Hee Arii. She is good [at] what she does and I guarantee you she will do whatever it takes for you to get a better trial. Thank you so much!
After a very frightening arrest for DUI, I entered my information into a search engine for attorneys. Ms. Arii contacted me within hours. She was knowledgeable and kind, and patiently explained my circumstances and options. She was able to secure PBJ with unsupervised probation, as it was my first and only offense. Her price is lower than many other attorneys and her level of service and expertise are outstanding.
Ms. Arii was of great assistance to me in representing my case in court (successfully). She was professional and personable at all times, but also asked me the tough questions to ensure she had all the facts of the matter before advising me on a legal course of action.
She was successful in [obtaining] a nolle prosequi (dismissal) of my DUI/DWI charges. I paid a $140 negligent driving ticket, a 1 point violation that will remain on my driving record for only 2 years. After court, after advising me of my expungement rights, I decided to file for [expungement] immediately by executing a General Waiver and Release. As a professional courtesy and without charge, she assisted me in filing the expungement paperwork. She was very professional, very friendly and I would absolutely hire her again and recommend her to others. Thank you Ms. [Arii]!
Facing a judge after blowing a .019 and reckless driving isn’t the easiest, but with Sei-Hee Arii by my side I was confident. She fought to get me the best outcome possible, which for me was a PBJ, 8 hrs of community service & to attend a [MADD] class. This was my first offense, but the courtroom did not want to take it easy on me by any means. Sei-Hee did everything in her power to help me with this case, including offering to go to trial if that’s what needed to be done. She definitely knows what she’s doing & she stood out in the courtroom compared to the other attorneys when it came to being [knowledgeable] about the law.
C. Sei-Hee Arii is a highly dedicated attorney who is well respected in the DMV community. Representation by Sei-Hee meant prompt assistance and feedback telephonically and electronically, excellent knowledge about all laws in this area and a very tenacious effort to defend our case. She’s not all talk, this attorney takes action. She defended our son and made sure that he did not have suffer negative consequences and judgment as he moves forward in life. She challenged him to make good choices and shared several great words of wisdom. I have the [utmost] respect for Sei-Hee as a professional and a good person in general. She really helped us through a very difficult time and case. I would definitely recommend Sei-Hee!
Sei-Hee is extremely competent and is willing to work with you. I had a DUI charge and she was very thorough about advising me about the different dynamics in court that may impact how I should plead (eg. how the judge typically rules in similar cases, presence of certain witnesses etc). Very responsive and empathetic as well! I’d definitely hire her again.
Very proficient, able to recognize positive opportunities for clients without hope.
Very experienced lawyer! helped win my MVA case and ensured my revoked license was restored back to me. I can now drive again. Thanks for your help.
I chose Sei-Hee after reading all these positive reviews and they were right! I thought my case was hopeless after a relatively good performance on the field sobriety tests but over a 0.08 BAC on the breathalyzer. I had zero experience with the law or how to choose a lawyer but after reading every single review for her and multiple other lawyers, it seemed like she would give me the best chance. More importantly, she was the only lawyer I met with who read my all papers in depth and gave me real advice about my individual case. I still remember her saying “I feel good about this case” and describing a similar case that she won, which gave me hope from my first meeting with her instead of the vague “we’ll see what we can do when we get more details” approach like every other lawyer.
I went through 6 months of hell until my trial, thinking my life and career were over because I would get a PBJ no matter what since I agreed to the breathalyzer. However, we got a good judge and she was able to get a NOT GUILTY verdict for me for all DWI/DUI charges and helped me get them expunged immediately afterward!! I ended up only paying for the traffic ticket. I was truly shocked and overjoyed by this outcome. Getting arrested for a DUI is a horrific situation to be in and I wouldn’t wish it on anyone, but if you are reading this just choose her!
