Welcome to Washington Gastroenterology
Washington Gastroenterology (WAGI) was formed with the merger of three western Washington-based gastroenterology (GI) practices: Digestive Health Specialists (based in the Tacoma/South Puget Sound region), along with Northwest Gastroenterology Associates and Overlake Internal Medicine Associates - Gastroenterology (both based in the Bellevue/Eastside area). Launched on January 1, 2018, WAGI is now the largest, most comprehensive private GI practice in Washington state. Our story includes a rich history of providing preeminent GI care for nearly five decades, combined with a vision of collaboration and innovation, in a new practice dedicated to extraordinary patient care now and into the future.
Dr. F. Dennis Waldron, founder of the group that would later be known as Digestive Health Specialists, formed the first GI practice in Tacoma in 1972. Likewise, Dr. James Wagner was the first gastroenterologist to practice in Bellevue, when he established the GI department of Overlake Internal Medicine Associates in 1973. He subsequently co-founded Northwest Gastroenterology Associates in 1986. Over the years, each of these practices flourished and expanded to add physicians, advanced practitioners, clinics and endoscopy center locations.
