Cornerstone Medical Group is a multi-specialty group consisting of primary care and specialty physicians in the metro Detroit area. Our physician group began in 1997 with a vision to provide integrated quality care to the local community. We have grown to over 70 physicians and midlevel providers in 20 offices that include family practice, internal medicine, pediatrics, endocrinology, hospitalists, podiatry and colorectal surgery. All of our physicians are on staff at a St. John Providence hospital. To meet the needs of all patients, we are also on staff at most local hospitals in the community.
