A client,
Ms Sei-Hee Arii is a powerful, caring and knowledgeable lawyer. On the 01/01/2022 at 11:57pm, I had DUI/DWI and Negligent driving vehicle in a careless and imprudent manner which are three charges. I was confused, frustrated and thought my whole life has come to an end. I contacted several lawyers, they told me that it will be difficult to win the MVA hearing and that I should go and put the ignition interlock device, which I will have to blow before the car will start and that will show that I have know alcohol in my system. That device will have to be in my car for one year. And that they will handle the case in court. I went on line again and I saw Ms Sei-Hee Arii profile / review and I called her, she listen to my case and told me that I should not worry, and that she is going to handle both the MVA hearing and the court case for me. She gave me hope when there was no hope. I had confidence in her base on her profile review and case records. So, on 14th-March-2022, we went for the MVA hearing, behold, Ms Sei-hee Arii Presented a wonderful defense and I warn the MVA hearing. Today 06 -September-2022, we went for the court case For the DUI,DWI and Reckless driving case and Ms Sei-Hee Ari did wonderfully well and all the charges were dropped. That is I warn my case. Ma'am, I am short of words, I am so proud of you. Please, if you have DUI/DWI, Just contact Ms Sei-Hee Arii and she is going to handle and solve the case for you.

DUI, DWI, and 3 other charges dismissed!!
I highly recommend Ms. Sei-Hee Arii. From the start, she calmed me down, and told me to focus on school and that everything would be okay. I trusted her and she fought for me. I was found not guilty on all 5 charges and am now walking away free from all charges. She also represented me in my MVA hearing and helped me avoid getting an interlock. She is literally a miracle worker! She did not give up on me and I couldn't be more grateful.

Very respectful and knowledgeable lawyer
My initial contact was through a short Google search, which I found Sei-Hee and her website nearly immediately. She returned a response within maybe an hour of my request for consult. Scheduled a time to speak over the phone, during covid and within the middle of the holiday season, for later on that day after receiving that response. After that consult, I hired her immediately, knowing that I'd found the representation I needed. I paid my initiall fee and set up scheduling to make monthly payments there after. She made me feel like an important client throughout the entire process. She made my MVA visits more tolerable and less painful after several attempts on my own to reinstate my license privileges. She continued to check in with me from time to time to assure me I wasn't alone, to relax and allow her to handle my troubles. She was very kind, respectful and knowledgeable about the court hearing process, different judges and what to expect from all angles, options that would serve my best interests. My day in court with Sei-Hee was a success and was very pleased with the end result and positive outcome. Sei- Hee presented a direct, kind and positive attitude throughout the entire experience, highly appreciate and recommend her representation!!

Thank you for everything! Excellent Defense Attorney!
After being pulled over and charged with a DUI, Sei-Hee Arii was recommended to me by a friend who Sei-Hee had represented for a similar case. From our first conversation Sei-Hee was honest with what I was facing and laid out a clear path to follow in order to get the best possible result. Her proactive measures helped me face my mistake head on, and then make a plan to attack it. Once we got to the day of court Sei-Hee was more than prepared for everything that was thrown at us. She was very clear with what the worst case scenario could be and articulated her plan if we were to go to trial. The confidence gained from Sei-Hee's knowledge of the Maryland court system gave me the certainty to fight my case instead of accepting the reduced offer of the State's attorney. As a result, Sei-Hee successfully litigated my case and all charges I faced were subsequently dismissed. Sei-Hee then showed why she is above and beyond other defense attorney's by staying and filling out my expungement paperwork with me on the spot. She didn't have to do this, and it goes to show that she truly cares about her clients. I honestly cannot recommend her enough!

Excellent Attorney
I had been arrested and charges with DUI, DWI and failure to remain at an accident; I contacted Sei-Hee Arri about my case and she agreed to represent me. Her professionalism, empathy and helpful advice were invaluable. Taking her advice and trusting her with my situation was very successful. She was able to get the DUI abd DWI nol pors and the accident charge reduced to negligent driving with 0 points and a minimul fine. I highly recommend her services to anyone dealing with DUI's and/or DWI's; she will fight for you and give sage advice due to her years of succesful experience.

Unbeatable legal service
I highly recommend in hiring Attorney Arii to represent you in your legal situation. I made a horrible mistake one night and decided to get behind the wheel after consuming A LOT of alcohol. I was stopped by the police and was facing three DUI charges. I also had an extremely high BAC level (2.5 times the legal limit) and I had different circumstances in my case that was not in my favor. I was very worried how my case was going to be handled and I consulted with 4 different attorneys and in the end, I chose atty Arii. Our first phone call, she told me the worst possible outcomes that can happen in my case (which is great to know the reality of all this) but she also told me different proactive measures I needed to take in order to successful overcome this. She was supportive from the moment we spoke and truly does show care in her client and to get the best possible outcome. My court date arrived and Attorney Arii was able to get all my DUI charges dropped and dismissed. She spoke with the State before my case was called and they had a proposal that she did not agree with and used her expertise to have the judge rule in her favor and got my case dismissed. If that doesn’t show her dedication in wanting to fight for her clients then I don’t know what does!!! Right after my case was dismissed, atty began filling out the paperwork in order to expunge this matter and have it completely removed from my record. It was such a relief to know I was free from this situation and didn’t receive a conviction nor a probation before judgement — all thanks to Attorney Sei-Hee Arii!! I will always be grateful for her professionalism, knowledge, and experience with the law.

Great DUI/DWI Attorney
Attorney C. Sei-Hei Arii did an outstanding job with handling my DWI/DUI case. She was very prompt and professional from the very beginning and told me very accurately what to expect. Unlike many others in court she had me well prepared in court and my case went very smooth. Her billing system was very affordable and she gave me great advice to follow after her services were exhausted. If given a DWI/DUI case, I strongly recommend her.

Supremely competent and professional
Sei-Hee is a professional strategist who put everything into my defense. She is capable and confident, detail oriented and has a deep understanding of MD legal and judicial systems. She was genuinely empathetic to me and advised me in a way that was sensitive and compassionate. She knew details about my case that I did not see and prepared several alternate courses of action for us to take in my defense. It was no small feat to help me and I am grateful that she took my difficult case. Thank you for reading! ~MD

DUI/DWI Charge Dropped!
I found Sei-Hee at my darkest moment, and she help me get through it from start to finish. From the initial call, Sei-Hee took her time and showed genuine interest to help me beat my case, which she did! I was facing a DUI/DWI and potential suspension of license with MVA and Sei-Hee was able to use her expertise to get the charges dropped completely. She is truly passionate about what she does and is fair on pricing. She even worked out a payment plan with me which no other attorney at her level of competency provided. I will forever be grateful for Sei-Hee and her hard work and dedication to the case.

If you need the best, call Sei-Hee Arii!
Throughout my case Sei-Hee Arii was professional, organized, and fought for the facts to come out in my case. She provided great advice prior to even going to court to ensure I was on the right track to appear. She delivered on her words and her advice was spot on. We went to trial and ultimately I was found Not Guilty of the DUI and DWI charges! Highly recommend her if you

Excellent and knowledgeable
Ms. Arii is an incredible lawyer - she is smart and helped guide me through a DUI charge. I knew from our first conversation that I would be hiring her. She is readily available and answered all my questions, even giving me the worst case scenarios (upon my request). After hiring her, she did everything she could to speak to the prosecutor and get a charge pled down. Her tenacity is admirable. I cannot recommend Mrs. Arii enough.

If you need a DUI lawyer, look NO further.
Ms. Arii was professional, honest, easy to talk to, and knowledgeable. Before the first consultation was over, I felt comfortable and confident that she would be able to get me a positive outcome, even though some of the details of my DUI case weren't so favorable for me. She was very realistic, yet put me at ease with her professional opinion on how she thought the case might go. She walked me through everything and gave me some specific recommendations to prepare for my court date -- I could tell that she was very experienced with these cases. My court date was postponed over a year because of COVID, but she remained available for any questions or concerns throughout. At the end of the day, ALL the charges filed against me were dropped. It's a HUGE relief, and I would 100% recommend her to anyone fighting a DUI!

DUI
After I was being charged for DUI, I was the most scared person alive but after talking to a couple of lawyers I had recommendations to talk to Mrs. Arii. Upon consulting with her I felt an instant relief as she was compassionate and very detail oriented. She outlined everything and made it so clear to me and today I am proud to say she help me by getting my DUI and many other charges dismissed. She is just amazing. Always reaching out and so patient with her client. I will definitely recommend her to anyone out there in need of an attorney to represent then with Sei-Hee you are well represented.
