After an accomplished career as an Assistant Prosecutor, Greg is thrilled to join the HCK firm as a defense attorney.  His previous defense work resulted in numerous acquittals on serious criminal matters and precedent-setting appellate and NJ Supreme Court decisions. 

Before joining the firm, Greg served as the First Assistant Prosecutor in Sussex County for nearly 15 years and as an Assistant Prosecutor for roughly 6 years in both Morris and Sussex counties. During his law enforcement career, he directly supervised all units at the Prosecutor’s Office with particular emphasis on the major crimes, public corruption, and appellate units. In 2020, the County Prosecutor’s Association of New Jersey awarded Greg the “outstanding advocacy” award for his successful trial work on several high-profile trial cases and his appellate advocacy before the New Jersey Supreme Court. This award is presented annually to one prosecutor, selected from the more than 1,000 statewide prosecutors. 

Greg has been an instructor for the New Jersey Association for Justice, the New Jersey Bar Association the New Jersey Attorney General Advocacy Institute and the County Prosecutors Association of New Jersey. Greg is a former adjunct law professor and mock trial coach for several high schools in his community.  

Greg has extensive experience dealing with the media in high-profile matters. His cases have been covered by the New York Times, the Los Angeles Times, the London Times, the Wall Street Journal and other internationally respected publications. He has been interviewed for news stories and documentaries by many major media and entertainment companies. 

Greg graduated cum laude from Duquesne University School of Law in 1995 where he won the American Jurisprudence Award and Corpus Juris Secundum award for scholastic excellence.  In his spare time, Greg’s hobbies include hiking, cross-training, writing, drawing and painting.
