About Maegen J. Wallace, MD

Maegen J. Wallace, MD, is a pediatric orthopedic surgeon who cares for infants, children and teens with conditions that affect the bones and soft tissues in the foot, hip and knee. As one of the nation's leading experts in osteogenesis imperfecta, a genetic disease that causes easily broken bones, often without obvious cause or significant injury, Dr. Wallace has brought a level of expertise to Phoenix Children's that currently does not exist anywhere else in the Southwest.

Previously, Dr. Wallace served as the director of the osteogenesis imperfecta and bone dysplasia clinics at Children's Hospital and Medical Center in Omaha. There, she served as the Dr. Paul and Bernadette Esposito Endowed Chair in pediatric bone disorders and associate professor of orthopedic surgery and rehabilitation. Dr. Wallace came to Phoenix Children's for the opportunity to be part of the health system's growing program for children with rare bone conditions.

A dream of becoming an orthopedic surgeon led Dr. Wallace to medical school at the University of Nebraska Medical Center in Omaha. Through her training, her passion for taking care of children was ignited. Dr. Wallace completed an orthopedic surgery residency at Saint Louis University in St. Louis, and a pediatric orthopedic surgery fellowship at AI DuPont Hospital for Children in Wilmington, Delaware.

Dr. Wallace is certified by the American Board of Orthopaedic Surgery. She is also certified by the Certification Board for Professionals in Patient Safety. Dr. Wallace is a fellow of the American Orthopaedic Association, the American Academy of Orthopaedic Surgeons, a specialty fellow of the American Academy of Pediatrics and a member of the Pediatric Orthopaedic Society of North America. She also serves on the medical advisory council of the Osteogenesis Imperfecta Foundation and is a board member of the Jansen's Foundation. In 2021, Castle Connelly named her a Rising Star, and Omaha Magazine named her a Premier Doctor.

Through research, Dr. Wallace is focused on making and sharing discoveries to help improve the lives of children with bone disorders. She has published in numerous professional publications and books, and presented at national and international conferences and meetings, including the Canadian Pediatric Orthopaedic Trauma Meeting and OI TeleEcho, an Osteogenesis Imperfecta Foundation educational program.

Dr. Wallace provides patients and families with the highest quality of care possible, while reducing pain. She works with patients to support them when surgery can help prevent fractures, and she helps them reach developmental milestones and function better.

When she is not working, Dr. Wallace enjoys spending time with her three children and being outdoors.

Very pleased

We appreciated that the visit was right in time. We were seen very quickly upon arriving for our scheduled appointment. We did not spend much time at all waiting. The provider was respectful of our time and my daughter's needs. She took time to answer my daughter's specific questions as well as mine and was especially considerate and responsive to our concerns and preferences regarding her treatment plan. We also want to acknowledge the professionalism and respectful treatment from the staff who checked us in as well as the different staff who fitted her for braces. The entire encounter from arrival to completion was excellent.

I just genuinely liked Dr. Wallace. She approached us in a friendly manner and we both felt very comfortable.
