  • During my fellowship, I received advanced training in shoulder and elbow replacements, shoulder and elbow arthroscopy, shoulder and elbow instability, upper extremity fractures, rotator cuff repairs, tendon transfers for the shoulder, and sports injuries surrounding the shoulder and elbow, including Tommy John surgery, also known as ulnar collateral ligament (UCL) reconstruction. In addition to the shoulder and elbow, I treat both operative and non-operative fractures throughout the body. I have published numerous book chapters, journal articles, and surgical training videos for shoulder and elbow surgery. I incorporate evidence-based practices with the latest medical research and cutting-edge treatments to provide my patients the best possible care.
