    I wholeheartedly endorse this attorney and firmly believe that he is the finest criminal trial lawyer currently practicing in Philadelphia. His ability to persuade both judges and juries is literally unmatched and - perhaps more importantly - he genuinely cares about the people he represents and the outcomes of their cases. I cannot think of any better attorney to hire should you ever find yourself facing the brunt of a state or federal criminal investigation or prosecution.
