Steven Sandberg-Lewis, ND, DHANP

  • College of Naturopathic Medicine

Dr. Steven Sandberg-Lewis has been a practicing naturopathic physician since 1978, treating patients at the NUNM Health Centers and also at his private practice – 8 Hearts Health and Wellness. His areas of specialty include:

  • Gastro-intestinal conditions
  • Chronic sinusitis and infections
  • Spinal, fascial and visceral manipulation

Dr. Sandberg-Lewis receives referrals of patients with digestive diseases who desire naturopathic treatment options for conditions that have defied diagnosis by other physicians. He understands the diseases of the gastrointestinal tract, and can often find successful treatments to regain normal function of the digestive system. He is one of the small number of physicians in the US with extensive knowledge and experience in treating small intestine bacterial overgrowth (SIBO).

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. He refers those with extensive intestinal adhesions to practitioners who specialize in other, more intensive manual techniques.

In addition to supervising clinical rotations at the NUNM Health Centers, Dr. Sandberg-Lewis teaches several gastroenterology courses at NUNM. He is also an investigator at NUNM’s Helfgott Research Institute.

Dr. Sandberg-Lewis lives in Portland with his wife, Kayle. His textbook, “Functional Gastroenterology” is available through the NUNM Press. In addition, he has produced a CD recording, “Talkin’ ‘Bout Degeneration,” a musical compilation of classics from the 60s and 70s with original lyrics about pathological conditions. His interests include mandolin, guitar and voice, as well as writing and lecturing at conferences nationally and internationally.
