Dr. Peter Newton is chief of the Division of Orthopedics & Scoliosis as well as surgeon-in-chief at Rady Children's Hospital-San Diego and a clinical professor at UC San Diego School of Medicine.

After earning his degree in bioengineering, Dr. Newton attended the University of Texas, Southwestern Medical School. He completed his residency at UC San Diego, followed by a fellowship in pediatric orthopedics and scoliosis at the Texas Scottish Rite Hospital in Dallas.

When it comes to patient care and special surgeries for sick children, Dr. Newton primarily treats scoliosis and other spinal conditions, such as vertebral fractures. On the research side, he has been involved in more than 200 publications; among his areas of focus are spine surgery, scoliosis without spinal fusion, and orthopedic biomechanics. Besides helping provide patient care and surgical services, he has also authored numerous books and book chapters.

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

In addition to his clinical practice providing special surgeries as a surgeon-in-chief, Dr. Newton enjoys travel, fishing, and auto mechanics.
