About Our Practice

Granite Peaks Gastroenterology is a GI specialty clinic serving patients along the Wasatch Front and throughout Utah. Our board-certified gastroenterologists are specially trained to help patients suffering from conditions of the digestive system find the right treatments to live their healthiest life.

In our Sandy and Lehi GI clinics, we see patients for office visits, medication and treatment management, and a variety of small procedures including hemorrhoid treatment, Pillcam testing and bloodwork. In Sandy, we have a state-of-the-art Endoscopy Center where our doctors perform procedures with our team of friendly, caring, experienced nurses and certified registered nurse anesthetists (CRNAs).

The Granite Peaks Endoscopy center is where patients visit for a colonoscopy, upper endoscopy (EGD) and treatment for esophageal strictures (dilation). We also test for and diagnose colon cancer, celiac disease, IBD/Ulcerative Colitis/Crohn’s disease, diverticulosis, lactose intolerance, liver disease, GERD, Barrett’s esophagus and more.

We understand digestive illness makes everyday life difficult. Since 2007, Granite Peaks Gastroenterology has served our patients’ digestive health needs. Our gastroenterology doctors use their decades of experience to find the best treatment options to bring our patients back to their best health.
