Dr. Lewis attended the University of Washington School of Medicine in Seattle, Washington and completed his pediatric residency training at Primary Children’s Medical Center in Salt Lake City, Utah. He was board certified in Pediatrics in 1993 and completed re-certification in 2000 and 2007. Before founding Sancta Familia Center for Integrative Medicine, LLC he practiced general pediatrics for ten years in Salt Lake City, Utah and Billings, Montana, and served for seven years as Medical Director of the Pfeiffer Treatment Center in Warrenville, Illinois, where he treated children and adults with learning, mood, and behavioral problems with targeted nutrient therapy.
His medical career was directed down a different path when his child was diagnosed with autism at age two. Without a functional framework in traditional medicine for treatment of his child’s autism and associated medical problems, Dr. Lewis began to explore integrative, holistic and functional medicine therapies. Dietary intervention, targeted nutrient supplementation, and approaching treatment with a more integrative/functional framework proved to be effective in helping his child, as well as many of his patients. In response to seeing such profound effects with these treatments, Dr. Lewis continued to explore other integrative medicine modalities and was certified by the American Board of Integrative Holistic Medicine in 2002 and re-certified in 2010.
Dr. Lewis became Medical Director of the Pfeiffer Treatment Center in 2003. In this role he was able to concentrate on the treatment of children and adults with learning, mood, and behavioral problems, such as ASD – autism spectrum disorder, ADHD, bipolar disease, mood disorders, and behavior disorder. Additionally, he participated in research resulting in two publications1,2 on oxidative stress/damage in children with autism and one publication3 regarding a clinical diagnosis commonly referred to as pyrrole disorder. The more integrative approach to the evaluation and management of learning, behavior, and mood problems he developed at the Pfeiffer Treatment Center facilitated a more predictable, effective, and reproducible approach to the treatment of patients with these medical conditions. He has spoken nationally and internationally regarding the targeted nutrient management of the learning, mood, and behavioral problems listed above and was invited to author an article for the Autism Society of America member publication Advocate4.
The Sancta Familia Center for Integrative Medicine, LLC (fka Integrative Pediatrics of Ohio, LLC) was founded in 2010. In the first year, Dr. Lewis started to see more patients with PANS/PANDAS and was interviewed by Tracy Townsend from Channel 10 News in Columbus, Ohio about PANDAS in November 2011 and her report aired that month. Subsequently, Dr. Lewis has been recognized as a leading physician by PANDASnetwork.org and is devoted to bring hope and healing to patients and their families affected by PANS/PANDAS. Naturally, this lead him to begin the life-long process of learning about and treating persons with Lyme Disease and related illnesses. Attending his first ILADS<ilads.org> conference in April 2014, Dr. Lewis has found the opportunity to find and treat the underlying causes of chronic illness in even more patients.
