GI Specialists

With six board-certified Gastroenterologists in Utah and 100-plus years of combined experience, Granite Peaks Gastroenterology has the capability to diagnose and treat your gastrointestinal problems.

Advanced Capabilities

At Granite Peaks Gastroenterology, our Gastroenterologists provide the complete range of modern gastroenterology care in our advanced screening and treatment clinics in Utah. This includes using state-of-the-art technologies and performing in-office procedures like endoscopy, colonoscopy screenings, GERD treatments, and hemorrhoid banding.

Exceptional Care

A complex system, the gastrointestinal tract can be affected by a number of disorders which are often subtle and difficult to understand. The GI specialists at Granite Peaks Gastroenterology focus not on a particular procedure or treatment, but on understanding and resolving your unique gastrointestinal problem.

New Clinic in Sandy
