Excellence

See-Hi was a very competent and knowledgeable attorney for my case. She made sure that I was prepared in all areas, for the courtroom. Her preparedness on the day of my trial, was top notch. Her delivery of my circumstances to the judge, included all important circumstances and events. Lastly,... strengths: incredibly sensitive to the client, very down to earth, and easily approachable, and is incredibly professional! I truly recommend her as an attorney that excels in her field.

I can breath again!

I had spoken with a handful of lawyers and am glad I went with Sei-Hee Arii! What stood out about her was her attention to detail. She asked me questions that none of the other lawyers did and THE DETAILS MATTER! I loved her aggressive approach to helping my case. Although I was anxious at first,... she assured me throughout the way, was honest about things to expect, responsive to questions and really there wasn’t much I had to do but trust her. While I am not happy that I had to go though this, I am happy that I picked Sei-Hee to represent me. She was able to get my DUI charges dismissed and prevented the suspension of my license. I recommend!

Thank you for saving the day, Sei-Hee!

Earlier this month, I was in court facing two criminal charges from a single traffic infraction. But because I made the wise decision months earlier to hire Sei-Hee, I was free from worry. Leading up to the trial, her combination of competence and straightforward communication put me at ease. Without... revealing specifics, Sei-Hee’s intimate knowledge of Maryland’s court system gave me a crucial advantage. As a result, she successfully secured the dismissal of both criminal charges and filed my expungement paperwork on the same day!

My confidence in Justice has been restored.

Used Sei-Hee to try, & clear up my son's driving record. He did not realize the ramifications points on a license have. He just went & paid his fine & accepted the. I retained Sei-Hee to see if we can some how get the points removed. She was the first attorney that I had spoken to that had convinced ...me that it was possible. After retaining her it started off bleek, but upon appeal we wound up getting a pre-trial court date. Well this is where she worked her Magic. I, and my son would have been more than happy to just have the points stricken from his record. Well Sei-Hee did way better than that. She managed to get the whole incident stricken from my son's driving record. In simple terms, I asked for a piece of cake, instead Sei-Hee delivered me a whole cake, with frosting, and a cherry on top. She exceeded my and my son's expectations competely. Sei-Hee has proven to be a very confident, competent, and empathetic attorney. I would not hesitate using her again in the future if the need arises.

Fantastic DUI lawyer!

Sei-Hee Arii is an outstanding attorney! She is very proactive and knowledgeable about the ins and out of the justice system. She was successful in obtaining a nolle prosequi (dismissal) of my criminal case (a DUI/DWI and reckless driving) in court on and at the MVA today. She was able to get my case...s dismissed when nobody else could. I would hardly recommend Ms. Sei-Hee Arii. Thank you so much Ms. Sei-Hee Arii!

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
