The right gastroenterology expertise—when and where you need it.

Regional Gi formed when both of Lancaster County’s long-trusted gastroenterology practices merged. Combined, our team can now match patients with experts in virtually any digestive condition that could affect you and your family. We also have specialists in procedures such as colonoscopy, endoscopy, and advanced surgeries. You can see any clinician you choose at any Regional Gi location.
