What Comprehensive Primary Care does

Comprehensive Primary Care (CPC) was a for-profit primary care provider network founded in 2012 and based in Germantown, Maryland. CPC has been acquired by CloseKnit and now operates under Atlas Health, LLC, trading as CloseKnit Primary & Immediate Care. The integrated entity runs 40+ clinic locations across Maryland, Northern Virginia, Washington D.C., and Massachusetts, offering primary care, immediate care, behavioral health, nutrition support, and new parent support services through a hybrid in-person and virtual delivery model.

The technology layer comprises a branded CloseKnit mobile application on iOS and Android, an online patient portal, and a virtual care platform that supports diagnosis, follow-ups, preventive care discussions, and symptom reviews on weekends and after hours. A Health Guides team provides free care coordination to schedule appointments, find specialists, and navigate insurance benefits. The platform is built on standard healthcare infrastructure with HITRUST CSF and SOC (non-CPA) certifications for information security compliance.

Revenue is generated predominantly through fee-for-service insurance reimbursement across a broad payer mix, including CareFirst, Blue Cross Blue Shield (multiple state plans), UnitedHealthcare, Cigna, Aetna, Anthem, Humana, Medicare, Medicare Advantage, Medicaid, Tricare, and Johns Hopkins Health Plans, with secondary self-pay revenue for uninsured patients. Go-to-market is direct-to-consumer in the DMV and Massachusetts regions, marketed via website, app stores, email newsletter, and patient testimonials. Distribution runs through physical clinic visits, telehealth, and self-serve patient portal channels.
