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 superior 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.
