Sean Marx, MD

Fellowship-Trained Sports Medicine Surgeon

Dr. Marx is a specialist in treating the shoulder, elbow, and knee. He has expertise in both arthroscopic and open techniques for injuries to ligaments, meniscus, cartilage, rotator cuff, and labrum in addition to shoulder replacement surgery. He enjoys treating patients and athletes of all ages and abilities, working to help them get back to the activities that are most important in their lives. His dedication to providing top-notch care has made him a trusted sports medicine physician, knee surgeon, and shoulder surgeon in San Antonio.

Dr. Marx attended the University of Notre Dame where he obtained a Bachelor of Science degree before returning closer to home to attend medical school at SUNY Upstate Medical University in Syracuse, NY. He remained at SUNY Upstate to complete his residency in orthopaedic surgery. He continued on in his training to the University of Kentucky for a fellowship in Sports Medicine where he learned and adopted cutting-edge techniques in both arthroscopic and open surgical procedures from leading experts in their field. During his training, Dr. Marx worked with and helped athletes of all ages including Division I athletes at Syracuse University, University of Kentucky, and Eastern Kentucky University.

When evaluating patients, Dr. Marx believes in taking a comprehensive approach which will include listening closely to patients' concerns, performing a thorough examination, and obtaining tests or imaging when necessary. It is important to him that all patients are treated with the utmost care and compassion. Oftentimes, many of our injuries will be amenable to conservative treatment modalities such as physical therapy, medication, or injections. When pain or dysfunction continues in spite of our best efforts at non-surgical treatment and surgery is indicated, Dr. Marx will be there with you every step of the way.

In his free time, Dr. Marx enjoys all things outdoors including skiing, hiking, and biking. He has participated in many triathlons and remains an avid runner where he continues to compete in races from 5K to the marathon. He enjoys spending time with his wife and going on adventures with his german shepherd, Winnie.

I was a little nervous due to my knee issue and he put me at ease with explaining what the issue was and what was needed to address my knee problem.
