Founded in 1929 by Dr. Michael 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. In 2018, Reliant Medical Group became part of Optum. We have over 500 providers, about 2,700 employees, and serve more than 320,000 patients in over 20 locations. We offer a unique collaborative approach to care that helps patients through sickness and health with compassion and a dedication to service. Be aware that we will never discuss career opportunities and job offers via an online chat. Job seekers should apply via our website.
