CLOs on the Move

Founded in 1929 by Dr. John Fallon, Reliant Medical Group was the first group medical practice established in Central Massachusetts. Known initially as Fallon Clinic, the name of the organization was changed to Reliant Medical Group in October, 2011. In 2015, Reliant Medical Group merged with Southboro Medical Group – a union that has created the largest independent medical group in Central and Metrowest Massachusetts. We are a non-profit, 501c(3) organization.
