Concentra was founded in 1979 and has grown to be the largest provider of occupational health care services in the country. Concentra was founded by physicians as a medical practice and, in those early days, our founding fathers played a significant role in creating the workplace health industry model that exists today. Perhaps most important, we continually raise the bar by adding more centers, hiring and retaining experienced professionals in occupational medicine, and carrying out our mission to improve the health of America’s workforce, one patient at a time.
