Sarah London is CEO of Centene Corporation, a Fortune 25 company and the nation’s leading healthcare payer focused on government-sponsored programs. Centene is dedicated to serving lower-income populations and those with complex medical needs through a deeply local approach. Under Sarah’s leadership, Centene has sharpened its focus on its three core businesses — Medicaid, Medicare, and Marketplace – and made significant investments in two growth areas: integrated care for the dually eligible population and a new form of health insurance for working individuals and families, known as Individual Coverage Health Reimbursement Arrangements (ICHRAs). Sarah has also prioritized building the company’s One CenTeam culture, which unites more than 60,000 employees around one common mission: to transform the health of the communities they serve, one person at a time. 

Sarah has spent her career at the intersection of data, technology, and healthcare transformation, bringing her expertise to a range of organizations from start-ups to Fortune 500 companies. Before joining Centene in 2020 and becoming the youngest female CEO of a Fortune 500 company in 2022, she held roles at Optum (a division of UnitedHealth Group); Humedica; Accretive Health (now R1 RCM); and Health Leads, where she first developed her passion for using data to improve health outcomes for underserved communities.

Sarah was included on Forbes’ “Power Women” list in 2024, has been named one of Fortune’s “Most Powerful Women” for three consecutive years, and was awarded Modern Healthcare’s “Leading Women Vanguard Award” in 2025. Additionally, under her leadership, Centene has been recognized by Fortune as one of the “World’s Most Admired Companies” and one of “America’s Most Innovative Companies,” and by Newsweek as one of “America’s Greatest Workplaces.” 

Sarah graduated from Harvard College where she played Division I tennis, and she earned an MBA from the University of Chicago Booth School of Business.
