Grand Junction Gastroenterology is the largest gastroenterology group serving western Colorado. Our staff currently includes five board certified Gastroenterologists, , two Physician Assistants and over 20 employees. Our goal is to provide our patients, referring physicians and the surrounding community with the best, most comprehensive, and highest quality of care possible.
Because gastrointestinal diseases require continuity of care, we strive to align patients with a single gastroenterologist who communicates with you, your primary care clinician, and your other specialists.
A gastroenterologist on staff is always on call for established patients with urgent needs.
Referred patients are evaluated in the clinic in person or by confidential telehealth. Although some testing is done in the clinic, the sedated endoscopies are performed by our physicians at the adjacent endoscopy center, St. Mary’s Hospital, Community Hospital, and Colorado Canyonlands Hospital.
We look forward to helping you.
