    We are Prepared to Fight Your Criminal Case Through Trial

    We are dedicated to protecting the rights and earning the respect of every single client.  We accomplish that goal by staying steps ahead of the prosecution and always being fully prepared to fight your case through trial before a judge or jury.  We work with a variety of special investigators, forensic experts and hair and fiber analysts to both challenge the evidence against our clients and question the prosecution’s theory of the case.

    We believe that the best defense is a strong offense.  Our attorneys commence investigating your case and preparing a defense from the moment you retain our legal services.  So, we do not sit back and merely let the District Attorney present its case.  We challenge the admissibility of evidence with pre-trial motions and prepare our own theory of the case, which we present in opening statements and weave throughout both the cross-examination of Commonwealth witnesses and the presentation of our own case.
