Trusted By The Razorbacks

Our practice is trusted by the region's top athletes, including the Arkansas Razorbacks. We're the official and exclusive orthopaedic & sports medicine provider for all of their teams, as well as many area high schools. We take pride in helping not only student-athletes, but also weekend warriors and anyone who has experienced an injury or is dealing with pain in their joints. We're here to get you back to your personal best. 

Experts In Our Field

We're experts in the areas of modern, minimally invasive techniques and offer a caring environment. In addition to sports medicine, our specialties include joint replacement, shoulder repair, knee reconstruction, cartilage restoration, fracture care and a growing list of non-surgical services. When surgery is necessary, most are performed on an outpatient basis.
