Steven Sandberg-Lewis, ND, DHANP


Dr. Steven Sandberg-Lewis has been a practicing naturopathic physician for over 40 years, previously on Orcas Island in Washington state and now exclusively at the NCNM Clinic. His areas of specialty include:

● Gastro-intestinal conditions
● Traumatic brain injury rehabilitation
● Chronic sinusitis and infections
● Spinal manipulation
● Soft tissue techniques – including structural integration

Dr. Sandberg-Lewis receives referrals of patients with digestive diseases who desire naturopathic treatment options; and often these are conditions that have defied diagnosis by other physicians. He understands the diseases of the gastrointestinal tract, but also can assess function and often find successful treatments to regain normal function of the digestive system.

He also focuses on the influence of stress on the body's physiology. Using soft tissue techniques such as structural integration, he effectively addresses injuries, post-surgical problems, and chronic pain by increasing blood flow and facilitating flexibility to affected areas. Visceral manipulation of the abdomen allows him to solve structural digestive problems often unaddressed by other healthcare providers. His expertise in physical medicine also includes releasing spinal restrictions and malpositions using naturopathic manipulative therapy. 

As the co-supervisor of the psychophysiology clinic rotation, he empowers and teaches his patients to gain conscious influence over physiology through general biofeedback, neurofeedback (brain-wave biofeedback), and other therapies. These methods work well with conditions ranging from head injuries and chronic pain to mood disorders and attention difficulties. 

In addition to supervising clinical rotations at the NCNM Clinic, as a full-time faculty member, Dr. Sandberg-Lewis teaches several academic courses such as pathology, gastroenterology and psychophysiology at NCNM. He is also an investigator at NCNM's Helfgott Research Institute.

Dr. Sandberg-Lewis lives in Portland with his wife, Kayle and his son, Ezra. His CD, “Talking ‘Bout Degeneration,” a musical compilation of classics from the 60s and 70s with original lyrics about pathological conditions, is available at the NCNM bookstore. All proceeds go toward funding academic scholarships. His interests include mandolin, guitar and voice, as well as writing and lecturing with Kayle.
