Jon is a lifelong Philadelphia area resident, living in center city and now in Montgomery County, Pennsylvania.

He then obtained his license to practice law in 1986 with bar admission in both Pennsylvania and New Jersey.

Jon has been a plaintiff’s personal injury lawyer since day one, trying his first case only a few months after passing the bar. Jon has been practicing law for over 35 years, he has tried hundreds of cases, and gotten clients millions of dollars in recovery for their injuries. His experience and knowledge in handling catastrophic personal injury cases is second to none.

Jon has been voted a Top 100 Trial Lawyer by the American Society of Legal  Advocates, and achieved a perfect 10.0 rating on legal ranking site – but he is most proud of the great reviews he has received from his clients. These reviews and results speak volumes to his qualities as a trial lawyer.
