UCLA Health System, the prestigious academic Los Angeles medical institution, is expanding its footprint into the San Fernando and Conejo Valleys.

The system, whose main hospital is the Ronald Reagan UCLA Medical Center in Westwood, is planning a regional hub in Calabasas, which will consist of a 55,000 square foot office building housing extensive imaging and diagnostic services, said Ann Sullivan, project director at the UCLA department of medicine. A location has been identified but the deal is not yet finalized, sources said.

In addition, the system is planning several outlying medical buildings in Thousand Oaks, Westlake Village, Porter Ranch and Santa Clarita, Sullivan said. Each medical office building will house imaging services, specialty physicians and primary care doctors.

The system has had an oncology practice in the valleys, which allowed cancer patients to receive their chemotherapy locally. The practices were very successful, Sullivan said, and led the institution to believe it can expand its presence in outlying areas of Los Angeles. The system is planning both a north and south expansion, with a medical office also planned for Redondo Beach.

“It will provide access for patients without the need to travel to Westwood,” Sullivan said.
