History & Services

Dr. Wenham established his practice in Colorado Springs in 1980. Dr. Van Os joined him in 1996 and Associates in Gastroenterology has since added several physicians through the present time.

Currently, we have 7 physicians and 6 mid-level providers all trained in gastroenterology and hepatology.

We strive to be a physician practice dedicated to state-of-the-art care for patients with gastrointestinal and liver diseases.

We perform endoscopic procedures including colonoscopy, upper endoscopy (EGD), biliary endoscopy/ERCP, endoscopic ultrasound (EUS), and are skilled in the therapeutic maneuvers associated with each.

We treat gastrointestinal and liver disease including inflammatory bowel disease, celiac disease, gastrointestinal malignancy including colon cancer, esophageal disease, viral hepatitis, irritable bowel syndrome, and GERD, to name just a few.

Please call us at (719) 635-7321 or have your primary care physician arrange for a referral if you would like to be seen by one of our providers.
