Brent Keith Holliman, PA

As founder and CEO of Ortho Plus, Keith strongly believes that accessibility and availability are key in healthcare. Keith feels that “patients should get the care they need when they need it most.” This was the main focus of Ortho Plus when it opened in 2016 and remains so today.

A key part of Keith's vision is to expand the network of participating surgeons and physicians by opening more orthopedic clinics. By doing so, everyone will be able to receive quality specialty care.

Background

Keith's extensive orthopedic experience, spanning over 30 years, has been enriched by his practice in medical administration for 14 years.

After graduating from the University of Oklahoma Physician Associate's Program in 1992, he spent most of his professional life in Orthopedic Surgery & Sports Medicine. He was later appointed Chief Operating Officer of a local physician-owned hospital, followed by a position as Vice President of Outpatient Physical Therapy Services, where he helped develop physical therapy centers around Oklahoma.

Keith soon became a leader in opening several urgent care centers before they were mainstream. Keith then began working for a comprehensive healthcare system in Oklahoma City as the Director of Billing. His extensive knowledge of medical billing, electronic medical records, and clinical development helped him succeed in this role.

Next, he was promoted to Vice President of Surgical Specialty Clinics, where he remained until 2016. During that time, Keith witnessed the difficulty patients experienced accessing quality specialty care such as orthopedic surgery.
