Gastroenlerology Masterclass 2018



Dr. Steven Sandberg-Lewis ND, DHZNP

Steven has been a practicing naturopathic physician since his graduation from National College of Naturopathic Medicine (now NUNM) in 1978.

He has been a professor at NUNM since 1985, teaching a variety of courses but primarily focusing on gastroenterology.


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. Dr. Sandberg-Lewis is the author of the medical textbook Functional Gastroenterology: Assessing and Addressing the Causes of Functional Digestive Disorders, Second Edition, 2017. 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.g on gastroenterology and GI physical medicine. His clinic rotations are particularly popular among NUNM doctoral students. In addition to supervising clinical rotations, he also maintains a part-time practice at 8 Hearts Health & Wellness in Portland.

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.


Kayle Sandberg-Lewis, LMT, MA, BCN 

Kayle holds a master’s degree in Behavioral Medicine from Goddard College.

Her initial training in peripheral biofeedback – heart rate, temperature, etc. – was at Applied Psychophysiology Institute of Bainbridge Island, Washington followed by supervision under John Jordy at Western Washington University.

She started studying neurofeedback with Sue Othmer in 1994, and added it to her thriving stress management practice in 1996. In 2001 she began her on-going training with Dr. Len Ochs, the inventor of the Low Energy Neurofeedback System which has become a favorite among her many tools. Kayle is certified by the Biofeedback Certification International Alliance.

Kayle loves to teach. She has presented at local, regional, national and international conferences. She is an adjunct member of the faculty at National College of Natural Medicine (Portland, Oregon), where she teaches Behavioral Medicine.

A survivor of multiple “mild” TBIs, Kayle has found that many of her most memorable and rewarding cases have been survivors of traumatic brain injury.
