                                                    He is a popular international lecturer at functional medicine seminars, presents webinars, writes

                                                    articles for NDNR and the Townsend Letter and is frequently interviewed on issues of digestive health

                                                    and disease. He is the author of the medical textbook Functional Gastroenterology: Assessing and

                                                    Addressing the Causes of Functional Digestive Disorders, Second Edition, 2017, which is available at In 2010 he co-founded the SIBO Center at NUNM which is one of only four centers in the U.S. for small intestine bacterial overgrowth diagnosis, treatment, education and research. In 2014 he was named one of the “Top Docs” in Portland Monthly magazine’s yearly healthcare issue and in 2015 was inducted into the OANP/NUNM Hall of Fame.

Within gastroenterology, he has special interest and expertise in inflammatory bowel disease (including microscopic colitis), irritable bowel syndrome (including post-infectious IBS), small intestine bacterial overgrowth (SIBO), hiatal hernia, gastroesophageal and bile reflux (GERD), biliary dyskinesia, and chronic states of nausea and vomiting.

Many of the patients referred to Dr. Sandberg-Lewis have digestive conditions that have defied diagnosis and effective resolution. Often these patients desire naturopathic treatment options in lieu of the courses of treatments they have previously undergone. He understands diseases of the gastrointestinal tract, but also can assess function and often find successful treatments to regain a balance in the digestive system.

Dr. Sandberg-Lewis lives in Portland with his wife, Kayle. His interests include mandolin, guitar and voice; cross country skiing; writing and lecturing.
