About me

As a former New York Assistant District Attorney and ARMY JAG Officer, my experience in criminal law is both extensive and diverse.  Unlike many "general practitioners" my practice is devoted exclusively to defending those accused of criminal offenses.  I have handled the most complex criminal cases and tried dozens to verdict.  I appear regularly as a legal commentator on Fox News Channel and CNN, and my cases have received national and international coverage. 


I believe what differentiates me from other attorneys is the individual attention and compassion I show to my clients.   I take a special pride in being the lone voice for individuals facing the powerful machinations of the criminal justice system.  There is nothing more satisfying than a former client contacting me, months or years after their case is concluded, to tell me of the better times they now find themselves in.   


I have fulltime offices in both Manhattan and Long Island, and I handle criminal cases throughout the metropolitan area.


I reside in New York with my wife and two beautiful daughtersl.  When not practicing law I enjoy playing ice hockey, exercising, reading and travel.
