Mark Bertolini

Mark T. Bertolini was born in Detroit in 1956 and completed his undergraduate studies at Wayne State University in Detroit, Michigan, earning a BS in Business, and obtained an MBA from Cornell University's Samuel Curtis Johnson Graduate School of Management. Recognized as an accessible, forward-thinking and solutions-oriented leader, he transformed Aetna from a traditional health insurance company to a consumer-oriented healthcare company focused on delivering holistic integrated care to local communities and serving over 46 million people.

Bertolini held executive positions at Cigna, NYLCare Health Plans, and SelectCare before joining Aetna in 2003. He became CEO of Aetna on November 29, 2010, and chairman on April 8, 2011, until Aetna was sold to CVS in November 2018. He previously served as Co‑CEO of Bridgewater Associates (January 2022–March 2023) and has served as Chief Executive Officer of Oscar Health since April 2023. Bertolini is a national healthcare thought leader with extensive regulatory and public policy experience, having successfully navigated changes in the health insurance marketplace resulting from the Affordable Care Act.

He was recognized in Modern Healthcare's 100 Most Influential People in Healthcare in 2025 and has been recognized as a leader in corporate social responsibility for his historic decision to raise Aetna's base wage to $16 per hour and reduce out-of-pocket medical expenses for low-income households. In recognition of this decision, he was named to Fortune's 2015 list of the World's 50 Greatest Leaders and also to the 2015 Politico 50.
