The roots of DonJoy Performance lie in the rich sports medicine history of DJO Global, the brand's parent company. Founded as DonJoy in 1978 by Mark Nordquist, the Philadelphia Eagles' offensive line captain, and Ken Reed, a local lawyer, the company started out designing and producing simple sleeves. Over the years, with massive medical research and development and exceptional technological innovation, DJO Global has grown to become the leader in orthopedics and orthopedic rehabilitation, offering over one thousand medical devices that help people throughout the entire continuum of care, from injury prevention to rehabilitation. The DonJoy brand can be seen every day at the elite level of sports, with bracing, compression, and protective solutions in the training rooms and on every field of play. The world's top athletes, trainers and sports physicians have all come to trust DonJoy. And now we're happy to bring our exceptional technologies and compelling designs directly to athletes everywhere through retail and online distribution with the DonJoy Performance line.
