Dr. Newton primarily treats scoliosis and other spinal conditions, such as vertebral fractures. On the research side, he has been involved in more than 140 studies; among his areas of focus are spine surgery, scoliosis without spinal fusion, and orthopedic biomechanics. He has also authored numerous books and book chapters.

His professional affiliations include membership in numerous pediatric orthopedic organizations, including the American Academy of Orthopaedic Surgeons, Scoliosis Research Society and the Pediatric Orthopaedic Society of North America, where he was a former president.

In addition to his clinical practice, Dr. Newton enjoys travel, fishing and auto mechanics.
