The Team

Our team is 100% dedicated to treating pediatric scoliosis. We strive to provide the best treatment solutions and inspire confidence in everyone we meet.

Luke Stikeleather, Founder, President, and Chief Orthotist

As Founder, President, and Chief Orthotist of the National Scoliosis Center (NSC), Luke serves patients from all over the United States and the world at both his Fairfax and Baltimore locations. Luke’s passion is helping children with scoliosis, furthering treatment options, and participating in scoliosis research. He attends conferences, training, and support groups; always with an eye on improving the scoliosis journey for all.

A lifelong learner, Luke is always curious about finding the best way to treat patients with scoliosis. That’s why when he learned of the success Dr. Jacques Cheneau and Dr. Manuel Rigo were having with the Rigo Cheneau brace, Luke decided to study with Dr. Cheneau and Dr. Rigo. In 2004, Luke became the first orthotist to introduce the Rigo Cheneau brace to North America and he has been using this brace for his patients ever since—making adjustments as technology has advanced and continuing his research on the best methods of treatment.

Walter brings a diverse background and a plethora of knowledge to our team, having worked with orthotics and prosthetics since he was 14 years old. In fact, he is part of a very small group of professionals (approximately 10 in the world) with a dual discipline as an orthotist and a physical therapist trained in scoliosis-specific exercises (PSSE).

Born in Bogota, Colombia, Walter was introduced to orthotics at his father’s company, Articulos Orthopedicos. He earned a degree in Orthotics and Prosthetics from Northwestern University in Chicago, completed two residencies in Chicago at Scheck & Siress Prosthetics, Inc., and then he became the Lead Orthotist of a scoliosis clinic at the University of Chicago. He has also gained experience while working for Hanger Clinic and managing scoliosis clinics in both Florida and Texas.

Walter is active in the scoliosis community. He has attended both the SRS and SOSORT annual meetings to learn more about innovative technologies, evidence-based, non-operative treatment of scoliosis, and the Rigo concepts.

Walter initially came to visit and learn about National Scoliosis Center, but ultimately decided to join the team after seeing the way we care for patients and their families.
