Shoulder Surgeon in Dix Hills
Meet Dr. Michael J. Sileo
Board Certified Orthopedic Surgery & Sports Medicine

Dr. Sileo, a proud Long Island native, graduated magna cum laude from the College of William and Mary in 1998 and earned his medical degree at SUNY Stony Brook in 2002. His extensive training includes a surgical internship and orthopedic surgery residency at SUNY Stony Brook, where he was honored to serve as the administrative chief resident. He further honed his skills with a fellowship in sports medicine at Lenox Hill Hospital in Manhattan, where he was an assistant team orthopedist for the New York Jets and New York Islanders, among others. Dr. Sileo has published numerous articles on shoulder conditions, including rotator cuff tears and shoulder instability, and has presented his research at both regional and national conferences. He is board-certified by the American Board of Orthopaedic Surgery in both Orthopedic Surgery and Sports Medicine and is a Fellow of the American Academy of Orthopaedic Surgery (FAAOS).
Dr. Sileo is passionate about caring for athletes, both competitive and recreational. He is actively involved in the local community, often seen providing care on the sidelines of local football games. He specializes in arthroscopic and minimally invasive treatments for shoulder injuries, but also has vast experience in both operative and non-operative orthopedic care. Notably, he is one of the few surgeons in the tri-state area performing hip arthroscopy for labral tears and femoroacetabular impingement.
Dr. Sileo emphasizes a comprehensive approach that includes rehabilitation and training to prevent sports-related injuries. His interests extend to treating cartilage and meniscal injuries, platelet-rich plasma therapy, and fracture care. Currently, he serves as the Director for the Division of Sports Medicine at St. Charles Hospital and is the President of the St. Charles Medical Staff.
