I have my roots in Atlantic City where my grandfather was a Pharmacist and my father was a general practitioner. I came to Philadelphia for Medical School , Internship and Residency. After two years in the Military I returned to Philadelphia for an Academic career at Hahnemann University.

I won the Lindback Teaching Award, led the Student Programs in Internal Medicine, developed the first Federally funded Physician Assistant Program in the country and directed the Division of General Internal Medicine. I also served on and chaired multiple committees at the National Board of medical Examiners.

In 1990 I became one of the founders of NSIM, devoting myself to continuing the challenging career of practicing General Internal Medicine in a private practice group setting. The biggest challenge is continuous study to remain at the cutting edge of the Art and Science of Medicine. The second challenge is the evolution of a group practice as the health system changes and the team approach of the “Medical Home” is becoming the new practice model. The last challenge is recruitment and mentoring of outstanding young physicians who are such a vital component of NSIM.

Most important to me are the long term relationships with my patients and the stimulation of meeting new patients and starting new relationships

Outside of medicine I enjoy my family of females: my wife Evelyn, my 3 daughters Jill, Jane and Lynn and their families, including our 5 granddaughters I also love reading history and as many sports as I can squeeze into my free time.

COVID-19 Update

If you are sick or were exposed to someone with COVID-19, please contact our office. We are seeing sick patients in the office during special hours in the late afternoon, and we are still doing telehealth visits as well. We can perform both rapid COVID-19 testing and send-out COVID-19 testing at our office depending on what you need, as well as regular flu and strep testing too. Please schedule an appointment so you can discuss with a medical provider what is best for you.

Due to limited resources during the current COVID-19 surge, we will not be performing COVID-19 testing on patients who are asymptomatic and without any known exposure.

If you have been exposed to COVID-19, you should isolate at home until your appointment. The optimal window for testing is 5-7 days after an exposure, but please call us right away so we can make all of the proper arrangements for you.

If you live in the same household with someone who has been diagnosed with COVID-19, you are at a high risk of becoming infected. You should quarantine at home until you can be sure that you are not infected. Please schedule a telehealth visit for specific instructions for your individual situation.

Visit the CDC website for more instructions about what to do:
