Founded in 1974, UHC has become an industry front runner by offering a broad portfolio of products and services to help clients, both providers and purchasers of health care, successfully manage their health-care costs. UHC’s highly integrated range of products and services includes a network of owned and managed health plans as well as specialty companies that individually address key and fast-growing cost areas of health care. UHC’s unique business mix provides an ideal research and development environment for developing, testing, and refining health-care-management products and service.
