“Everyone deserves to thoroughly understand their condition and treatment options. My goal as a specialist is to provide my patients with the knowledge and confidence to make informed decisions about their health.”
Dr. Holmes was drawn to Gastroenterology because of the longitudinal relationships with patients, the exciting advances in the field of therapeutic endoscopy, and the intellectual challenge of taking care of several interlinked organ systems.
Dr. Holmes completed a therapeutic endoscopy fellowship at Thomas Jefferson University Hospital in Philadelphia, where he received advanced training in therapeutic EUS, ERCP, stenting of the gastrointestinal tract, endoscopic suturing, double-balloon enteroscopy, Barrett’s ablation, and other skills.
Dr. Holmes likes living in Portland because of the amazing food scene and the proximity to the great outdoors. When he isn’t working, Dr. Holmes enjoys hiking with his wife and son, camping, skiing, and watching his beloved Northwest sports teams.
