" Aaron, words cannot begin to tell you how appreciative I am of you/your firm, for all you did in my legal matter these past few months. Today was a great day. I think you for your professionalism/tenacity in getting my case suppressed/dismissed! Thank You Very Much. "


" I want to again thank you both for the deft, calm and professional manner in which you handled my case. Legal competence is often lacking these days, but you folks are truly skilled in representing a client, at least in my book. You made a potentially horrible situation bearable. I would highly recommend you to anyone, should that situation present itself. "

-Greg R.
