Dr. Allen T. Lewis's bio

Dr. Lewis is Board Certified in Pediatrics. He 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. Before founding Integrative Pediatrics of Ohio 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 son was diagnosed with autism at age two. Without a functional framework in traditional medicine for providing treatment of his son’s autism and associated medical problems, Dr. Lewis began to explore complementary medicine therapies. Dietary intervention, targeted nutrient supplementation, and approaching treatment with a more functional framework proved to be effective in helping his son, as well as many of his patients. In response to seeing such profound effects with these treatments Dr. Lewis continued to explore other complementary medicine modalities and was certified by the American Board of Holistic Medicine in 2002.

In 2003 Dr. Lewis became Medical Director of the Pfeiffer Treatment Center. In this role he was able to concentrate on the treatment of children (and adults) with learning, mood, and behavioral problems, such as autism spectrum disorders, ADHD, bipolar disease, mood disorder, and behavior disorder. Additionally, he participated in research resulting in two publications on oxidative stress/damage in children with autism and one publication 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 children with these medical conditions. He has spoken nationally and internationally regarding the targeted nutrient management of the learning, mood, and behavioral problems listed above, especially autism spectrum disorders, and was invited to author an article for the Autism Society of America member publication Advocate.
