Anemia | Biliary Disease | Esophageal Diseases | Gastroesophageal Reflux | Inflammatory Bowel Disease | Intestinal Diseases | Liver Disease | Peptic Ulcer Disease | Stomach Diseases/DisordersI have been a lifelong resident of the Philadelphia area. I graduated with honors from Temple University School of Medicine and completed an internal medicine residency and gastroenterology fellowship at Temple.
After initially practicing in Philadelphia and Lower Bucks County, I joined Drs. Jerome Burke and William O'Toole at Bux-Mont Gastroenterology in 1998. In 2019, I joined St. Luke's University Health Network
My practice style is collaborative. I stress the importance of the patient being an active participant in their own healthcare decisions.
I am a passionate fan of all the Philadelphia sports teams.
I enjoy spending time at the New Jersey shore and traveling with my family.
I live in Bucks County with my wife and three children.
