The Cleveland Clinic was at the forefront of modern medicine when its founders opened it as a multi-specialty group practice in 1921. In its first century, Cleveland Clinic has introduced many medical firsts, opened facilities around the world and is proud to be ranked among the top hospitals in the country. Now, 100 years later, the vision of the founders remains Cleveland Clinic’s mission: caring for life, researching for health, and educating those who serve.
