Founded in 1929 by Dr. Michael Fallon, and having become a part of Optum in April 2018, 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, Southboro Medical Group merged with Reliant Medical Group – a union that has created the largest independent medical group in Central and MetroWest Massachusetts.
