Why should you choose Oak Ridge Gastroenterology?

Over the last 37 years, we have served the Oak Ridge area and delivered quality care for digestive disorders. From simple problems like hemorrhoids and acid reflux to complex issues like celiac disease and GI cancers, we can help. Our physicians are acid reflux and colon cancer screening specialists. Using advanced technologies like video capsule endoscopy and endoscopic ultrasound, we strive to improve your digestive health.

In order to deliver you the best of care, our physicians perform procedures like Endoscopy and Colonoscopy at the award winning Endoscopy Center of Oak Ridge. The physicians and staff take pride in the exceptional care delivered in a safe, comfortable, and caring environment. 

And we’re connected with one of the nation’s highest performing health networks, Covenant Health. That means better care – for you and your family.

We are proud to sponsor the Knoxville Area Urban League Shoes for School annual event to provide our community’s children in need with new shoes and supplies to start the school year. This year, the event – and the contents of those supplies – look a little different, including Covenant Health face masks, but the impact for these young people remains paramount.

Families can pick up their supplies at the Knoxville Area Urban League starting at 9 a.m. Saturday. Best wishes to all students for a safe, healthy and fun year!
