Karen Lynch
Executive vice president, CVS Health and president, Aetna
Lynch’s stock has climbed quickly since the merger of CVS Health and Aetna in 2018 when she was named executive vice president while continuing to be president of Aetna. In less than two years, she was named CEO of CVS Health and will take on that role from Larry Merlo when he steps down in February. Lynch helped launch the Aetna Connected Plan, which offers certain MinuteClinic services at no cost, grow Medicare Advantage membership and incorporate HealthHUBs into Aetna's offerings, which focus on chronic care management. HealthHUBs will begin to offer in-person behavioral health services next year.
