• Northwest Gastroenterology Specialists

    At Northwest Gastroenterology Specialists we treat and manage a full spectrum of conditions and diseases of the digestive system. We also perform a variety of procedures including colonoscopy screenings for early detection of colon cancer at the Avista Adventist Hospital GI Lab.

    The American Society for Gastrointestinal Endoscopy (ASGE) has recognized Avista’s endoscopy suites for their quality services which are used to diagnose and treat digestive disorders—from gastroesophageal reflux disease (GERD) to colon cancer. ASGE has designed the only national program recognizing quality and safety in the practice of GI endoscopy.
