Welcome to Endoscopy Center at St. Mary

By definition, endoscopy means to "look inside." Each year, our skilled physicians perform thousands of endoscopic procedures including colonoscopy, upper endoscopy, and flexible sigmoidoscopy using a high-definition camera that provides narrow band imaging for the highest possible detection of cancerous and precancerous lesions. 

We are a licensed and nationally accredited, outpatient ambulatory surgery center situated on the campus of, and operating as a joint-venture with, the St. Mary Medical Center in Langhorne, Pa. We have been proud to serve the southeastern Pennsylvania, central New Jersey and greater Philadelphia communities since 2006 with a proven track record of providing expert care with excellent patient satisfaction. 

Our entire team of physicians, nurses and technicians is committed to providing the highest quality care.  We work in a compassionate manner in a comfortable setting.  

We’re close, we care, and we can help.
