Diagnostic Medical Group of Southern California

Diagnostic Medical Group of Southern California is a community-based outpatient diagnostic imaging provider in Southern California. The organization operates imaging centers in the San Gabriel Valley and offers MRI, CT, X-ray, bone density, nuclear medicine, ultrasound, mammography, and EKG services. It has served the local community since 1984 and appears to operate under the DMG brand. The company is healthcare-related but is not a drug-development biotech or pharma company; instead, it is a commercial radiology and diagnostic services business. Public disclosures indicate Apollo Medical Holdings, now Astrana Health, agreed in 2021 to acquire the remaining equity interests in DMG within three years, and DMG has been presented as part of Astrana Health's radiology network.
