Quick Answer
Centene was founded by Elizabeth "Betty" Brinn in 1984 in St. Louis, Missouri. The company is currently led by Sarah M. London.
The modern corporate entity traces its legal roots to 1984 when it was founded as a third-party administrator for Medicaid managed care, but its current strategic identity was forged through a series of aggressive acquisitions and organic expansions that transformed it from a regional player into a national powerhouse. The origin of Centene Corporation is not a single founding moment but a complex evolution of corporate consolidation, operational innovation, and the brutal economics of the global healthcare supply chain. The story begins in 1984 when the company was founded as a third-party administrator for Medicaid managed care, initially focusing on the administration of benefits for low-income individuals and families. The strategic shift occurred in the mid-2000s when the company successfully integrated the various administration networks, implemented a unified IT system, and began to focus on the administration of high-value specialty drugs and behavioral health therapies.
Brinn launched the nonprofit Medicaid plan that became Centene in Milwaukee in 1984, focused on helping low-income people access healthcare.
