About me

I have been a practicing attorney for 37 years. My professional career has been exclusively with the criminal justice system both as a prosecutor and as a defense attorney for the last 35 years. I have handled a variety of white collar cases, and cases charging assault, theft, fraud, robbery, murder, kidnapping, drug possession, drug distribution, endangering the wlelfare of a child, sexual assault, eluding, threats and all cases in the municipal courts of New Jersey, Superior Courts of New Jersey and federal courts nationwide. I have alot of energy and always give my clients valuable representation. I simply do not like to lose. I have written numerous articles and taught many seminars over the years. I enjoy representing my clients.
