HealthCare Partners

What HealthCare Partners does

HealthCare Partners, founded in 1992 and headquartered in Torrance, California, operates a large integrated medical group serving patients across Southern California. Operating today as Optum California under Optum, Inc. (UnitedHealth Group), the company delivers primary care, urgent care, specialty care, virtual care, Medicare Advantage, and Accountable Care Organization services through nearly 200 locations — including 80 urgent care centers and partnerships with 40 top hospitals — across five counties (Los Angeles, Orange, San Diego, Riverside, and San Bernardino), serving 3 million patients in Northern and Southern California.

The company's product surface spans in-person care delivery, a MyChart patient portal, the Optum Rx mobile application, and a suite of pharmacy sub-brands covering home delivery (Optum Rx), specialty and infusion pharmacy, rare disease therapy management (Frontier Therapies), pre-sorted medication delivery (divvyDOSE), and pharmacy services for mental health and complex conditions (Genoa Healthcare). The underlying technology is not publicly disclosed, but the digital layer supports appointment scheduling, prescription refills, bill pay, remote consultations, and care team messaging.

The business model combines fee-for-service clinical revenue with capitated risk arrangements typical of California delegated medical groups, augmented by Medicare Advantage plan participation and pharmacy revenue streams. Customer acquisition occurs through direct patient relationships, insurance plan network acceptance, hospital partnerships, and digital channels (corporate website, MyChart portal, mobile apps, and social media). Growth has been supported by acquisitions (notably WellHealth Quality Care in 2016) and by ongoing integration into Optum's broader payer-provider-pharmacy ecosystem.
