The most needed dui lawyer Maryland Let me start off by saying thank you so much Ms. Sei Hee. You were amazing and I will literally never forget you a day in my life. I had gotten a DUI charge a few months ago (October) and it was with an accident (I had hit a car and I was so confused). Anyway, it was homecoming and we know how that gets and I was driving home (do not drink and drive) and I spaced out and the next moment I was in the back of someones car. I ended up refusing a breath test and I was told I'm under arrest. I quickly agreed to do the test but the officer told me it's too late but ended up taking me to the station to do the test. I blew a highh number :) and had to get picked up from the station but I did not have a mugshot or anything. Anyway, we had phone calls and she was straight forward as to what my case was looking like with what I was telling her (was not looking too good especially since I was in PG county...) She told me she will send me a list of things to do and to get them done BEFORE my court date. I did get everything done but I was still waiting to hear back on what is next. I was in a panic because duh, why would I not be after they tell you you can go to jail. I had started some of the request before even getting a lawyer (I was just smart enough to know I had to get started the same day after I got released) but she put the cherry on top so I can get the best result. So if you feel like you don't need a lawyer take it from me and get one. You do not know the terminology they are using or even if that is going to result in your best outcome. Moving along, it was getting closer to my court date and we were still waiting on my police report and the videos and this that and the third and they never came so now I'm panicking again because this is the evidence that can make or break my case. I remember stress shopping while talking to her literally the day before my court date.. Like 6 pm and I had to be at court at 8 am the next day. (I got my court date literally less than two months after the accident so work quick with getting her as your lawyer)(I had less than 50 days to do everything needed) and they were uploading the documents LESS THAN A DAY BEFORE MY CASE. Sei Hee told me not to worry because it is not my fault they waited till the last minute and she's going to fight this in court (that is a main reason you need to do everything she tells you to do, so they can't really say you did not learn anything from the situation). Going into court she told me get there early and dress nicely (please dress up guys) so I'm there as soon as the judge is there because he likes to start early (only someone who is working in the courts would know a judge likes to start early.. and once we got in the room people were saying hello to her and smiling). When I got there the officer also showed up and they were trying to postpone my date (my heart was beating so fast because I wanted it to be over it so bad) and Ms. Sei Hee talked to the needed people and she told me and my mother once again do not worry she's going to fight as she did. When I tell you guys I was standing up there for no more than a minute and thirty seconds I kid you not I only say "yes" and "thank you, have a good day" to the judge after him telling me I'm on PBJ !!!!!! I did have to pay $200 but that was nothing compared to the 2000 it was before hand. I got no points, no record and my life back. She's amazing. I got her a month before my court date and I'm so glad I went with her. She has a flat rate which is fair compared to others in the area. She guides you on what needs to be done. She gives you a speech on never do this again and gives you the warmest smile. I got the best outcome for my situation because it was looking rough at first but thank you to Arii Law Firm. <3 (Sorry for any spelling errors guys, just read the story :D).

Kind, Compassionate Attorney who gets results I recently had the opportunity to work with Sei-Hee Arii on my DUI case, and I couldn’t be more grateful for her guidance and expertise. From our very first conversation, she demonstrated professionalism, attentiveness, and genuine care for my situation. She personally answered my calls, took the time to listen, and reassured me that sometimes good people find themselves in tough situations. That level of compassion made all the difference during a stressful time. Sei-Hee was incredibly thorough in her approach—she meticulously reviewed every detail of my case, patiently explained my options, and kept me informed at every stage. Her deep knowledge of DUI law and strategic approach gave me confidence that I was in the best hands. She was always well-prepared and proactive in addressing any concerns, ensuring no detail was overlooked. What truly set Sei-Hee apart was her communication and dedication. She kept me updated throughout the process, making sure I always understood what was happening. Her professionalism, combined with her empathy, made a difficult situation much easier to manage. Thanks to her hard work and expertise, my case had a favorable outcome, and even after it was resolved, she continued to provide guidance when I needed it. I highly recommend Sei-Hee Arii to anyone in need of a knowledgeable, dedicated, and compassionate attorney. She genuinely cares about her clients and goes above and beyond to achieve the best results. Thank you, Sei-Hee, for your outstanding service and unwavering support!
