​Although the medical group goes back over many years, our PPMG foundation was started by Dr. John Shaw in 2012. Dr. Shaw is remembered as a very kind and caring person who loved his patients. He was dedicated and accessible, and never turned anyone away. His commitment to the community was evident in his success of this practice and the continued expressions of praise by his patients, past and present.​
