Centene Corporation

Centene Corporation is a leading American healthcare enterprise headquartered in St. Louis, Missouri. Founded in 1984, its core mission is to help people live healthier lives by increasing access to affordable, quality-focused healthcare, particularly for under-insured and uninsured individuals. The company operates as a managed care organization, transforming the health of the communities it serves through a uniquely local approach.

Centene provides a comprehensive spectrum of managed healthcare products and services, primarily focusing on government-sponsored programs. Its key market segments include Medicaid, Medicare (including Medicare Advantage and Prescription Drug Plans), and the Health Insurance Marketplace (Affordable Care Act). Additionally, Centene offers various specialty solutions such as behavioral healthcare, pharmacy benefit management, dental, and vision services. Notable brands associated with Centene include Wellcare and Ambetter Health.

Currently led by CEO Sarah M. London, Centene is navigating a dynamic healthcare landscape. The company has recently focused on its three core lines of business: Medicaid, Medicare, and the Health Insurance Marketplace, and remains the largest Medicaid managed care organization and the longest-running carrier in the Health Insurance Marketplace. Recent executive leadership changes in April 2026 saw the appointment of Daniel Finke as Group President, Markets and Commercial, and Michael Carson as Group President, Medicare and Specialty. The company is strategically addressing declining Medicaid enrollment by capitalizing on the growing Individual Affordable Care Act market and prioritizing Medicare Advantage profitability over membership growth.
