Fantastic Attorney and a great guy, handled everything, explained in detail, from the DMV hearing (which we won), to dealing with the court, secured a great outcome. HIGHLY recommend, Cannot recommend Mr. Ewin and his office enough.

I worked with Mr. Ewin to help clear old charges off of my record. From the first inquiry I made, he outlined all of the information he needed me to provide to achieve my desired outcome. He was also up front about the cost needed to complete the process, which was very smooth from start to finish. I only had to make one short (and optional) appearance in court. Very helpful and professional!
