Jordan D. Metzl, MD, is a nationally recognized sports medicine physician at Hospital for Special Surgery, in New York City. His practice treats more than 20,000 patients and he is regularly voted among New York's top sports medicine doctors by New York magazine. He lectures and teaches all over the world and has appeared on the Today show and Good Morning America.

Dr. Metzl specializes in nonsurgical treatment, working to help patients get back to their favorite activities as soon as is safely possible. He also strives to be a positive example for his patients, teaching his "Iron Strength" workout classes on weekends and maintaining his own fitness at an elite level. "I love being fit and active, and I like to encourage others to do the same," he says. "I feel like being a role model for my patients really helps me communicate with them better. I want to keep them on the field because I know how much better I feel when I'm out there doing what I love to do. Fitness keeps me injury-free and helps me in all aspects of my life, both inside and outside the office."
