What does Oak Street Health do?

Oak Street Health, based in Chicago, is a network of primary care centers focused on providing value-based care for older adults and Medicare-eligible patients with disabilities. Founded in 2012, the company has expanded significantly, operating over 230 centers across 27 states as of late 2025. In May 2023, Oak Street Health became part of CVS Health, enhancing its ability to deliver integrated care. The company emphasizes comprehensive primary care tailored to the needs of older adults. Its approach includes personalized wellness plans, regular checkups, and preventive care, all designed to manage chronic conditions and improve overall health outcomes. With smaller patient panels, Oak Street Health fosters deeper relationships between providers and patients, leading to better care experiences. The model has demonstrated strong results, including significant reductions in hospital admissions and emergency department visits.
