Excellent lawyer

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

Excellent Lawyer

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 do much better, she explained what my next steps should be l...eading 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..

DUI case

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 D...WI which is the lesser of the two. I'm happy with my outcome.

Excellent lawyer and very professional

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 smoot...h 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.

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.
