The physicians at Mid-Maryland Musculoskeletal Institute (MMI) are dedicated to providing excellent medical care and exceptional customer service.
In all cases, our goal is the same: to provide the highest quality of life with the least risk. All conservative treatment options will be exhausted before surgical intervention is recommended. All patients requiring surgery will be fully briefed on the procedure, any potential risks, and the post-surgical rehabilitation process. As part of our total approach to treatment, we provide patients with personalized care that includes physical therapy and training recommendations. Our physicians are trained in the latest minimally invasive techniques such as arthroscopy of the shoulder, elbow, wrist, ankle, and knee.
