She really cares about you. Not just the case. Ari resolved my issue on two separate occasions. The results were better than I expected. She kept me up to date on the process. Has an online checklist to make sure I stayed on task before the court date. Most importantly she was very empathetic. Even though she was swamped with cases I felt as if I was her only case. Sent me to classes not only to help with my case but to help with my mental. I would recommend her to anyone seeking counsel.

Best Lawyer in Maryland Sei-Hee Arii was an amazing lawyer throughout my DWI/DUI case. She spent endless nights working my case, reviewing footage, and other evidence. She is extremely knowledgeable about the law, and went above and beyond to make sire she has every plan was set. She resolved my case by getting my case dismissed and expunged. She got me a PBJ on a citation which prevented me from receiving any points on my license She always kept me informed of any new information that came out. Even if the information was small, she would give me a call and explain the information given. She helped me with every single process during the case. Not only was she professional and courteous, but she was also EXTREMELY caring and empathetic. I, myself am a student and she would always reassure me to not worry and to continue focusing on my studies. When she tells you she will work your case, she will work your case day and night. I will HIGHLY recommend anyone who is currently seeking legal advice to contact Sei-Hee Arii and have her be by your side.
