MedQuest Associates, a chain of more than 50 medical imaging centers that is planning to use new private equity backing to ratchet up expansion, has hired Chris Shea as chief legal officer.

Shea is the latest in a string of C-suite hires that the Atlanta-based company has made since announcing in January 2023 that it had formed a partnership with the San Francisco-based private equity firm TPG and Winston-Salem, North Carolina-based nonprofit health care system Novant Health to expand MedQuest nationally from its Southeastern U.S. footprint.
