Dr. Steven J. Thornton, MD
Board-Certified Orthopedic Surgeon | Sports Medicine Specialist | Dallas, TX
The Practice
Dr. Steven J. Thornton, MD is a board-certified orthopedic surgeon and sports medicine specialist serving patients throughout the Dallas and Fort Worth metroplex. With fellowship training at Cornell University’s Hospital for Special Surgery and decades of clinical experience, Dr. Thornton leads a practice built on one clear promise: expert, personalized care that helps patients get back to the life they love.
The practice specializes in minimally invasive procedures for shoulder, knee, hip, and elbow injuries, combining cutting-edge surgical technique with a genuinely patient centered approach that puts people, not just diagnoses, at the center of every decision.
How We Got Here
Dr. Thornton founded his practice in 2004 with a straightforward but ambitious goal: to bring fellowship-trained, subspecialty orthopedic expertise to patients in the Dallas and Fort Worth area without making them travel to a major academic medical center to get it.
Having trained at some of the most respected institutions in the country, including the University of Mississippi School of Medicine, UT Southwestern Medical Center for his residency, and Cornell University’s Hospital for Special Surgery for his fellowship, Dr. Thornton returned to North Texas with a depth of training that was uncommon in the region at the time.
Over the years, the practice has grown to serve patients at multiple locations across the metroplex, including Dallas, Frisco, Plano, Mesquite, and Arlington. What has never changed is the standard of care. Patients continue to see Dr. Thornton directly, receive individualized treatment plans, and benefit from surgical and nonsurgical expertise that has been recognized by peers and patients alike for more than two decades.
