Centene Corporation
A health insurer that runs government-sponsored plans, Centene covers tens of millions of people through Medicaid, Medicare, and its Ambetter Health marketplace plans, alongside specialty services like the AcariaHealth pharmacy. It began in 1984 when a former hospital bookkeeper, Elizabeth "Betty" Brinn, started a small nonprofit Medicaid plan in Milwaukee called Family Hospital Physician Associates. The company adopted the name "Centene" in 1997 from the Latin for "hundred," and its founding proceeds later helped create a children's foundation in Milwaukee.
