About me

I am the Managing Partner of Marshall, Bonus, Proetta & Oliver, one of the largest criminal defense firms in New Jersey. I have been appearing in both the Superior Court and local Municipal Courts throughout the state for well over twenty years, including years serving as a prosecutor. My efforts on behalf of my clients have resulted in many awards and accomplishments including being recognized as among the Top 100 Trial Lawyers by the National Trial Lawyers Association, Best Attorneys in America, Top 10 Criminal Attorneys in NJ by the National Academy of Criminal Defense Attorneys, the Ten Best by the American Institute of Criminal Law Attorneys, and as one of the Ten Leaders in NJ Criminal Defense. I am often asked to consult in newspapers and television, consulting with writers of Law and Order and House M.D., appearing on ABC, CNBC, CN12 and in the Star Ledger, USA Today and Asbury Park Press.

  • Thomas Hugh Martin

    I endorse this lawyer. I have known Jon since I opened my practice in 2005. He has always been one of the most knowledgeable and innovative lawyers I know. I have seen him zealously come to court time and time again on the same case until he received the result he knew was right for his client. He is a tireless advocate and very respected by the defense bar, prosecutors and judges.
