Karen S. Lynch

During the COVID-19 pandemic, Lynch took the helm as president and chief executive officer of CVS Health on February 1, 2021, following the retirement of Larry Merlo. The appointment made her the highest-ranking female CEO on the Fortune 500 list and the 40th female chief executive on the Fortune 500 list. Under Lynch's leadership, CVS Health administered the COVID-19 vaccine in more than 40,000 long-term care facilities and in CVS Pharmacy locations in 50 states, Puerto Rico and Washington, D.C.

Lynch was selected for the inaugural 2021 Forbes 50 Over 50, a list of female entrepreneurs, leaders, scientists, and creators who are over the age of 50. She was awarded the 2021 Committee for Economic Development Distinguished Leadership Award, which recognizes business leaders for their contributions. Additionally, Lynch is a board member of U.S. Bancorp, AHIP, The Business Council, Boston College Women’s Council, The Business Roundtable, and is an advisory board member of IBM Watson Health.

Lynch stayed with Magellan until 2012, when she joined Aetna as executive vice president and head of Specialty Products. Three months after joining Aetna, Lynch led the integration of Coventry Health Care, which was the largest health care acquisition at the time. In 2015, Lynch became Aetna's first female president, a role she retained through the $70 billion acquisition of Aetna by CVS Health in 2018.

Lynch credits her chosen career path in health care to her family life experiences. She spent nearly a decade in insurance before returning to graduate school to pursue her MBA, saying, "I wanted to broaden my financial background to have more exposure to the business aspects of running a company". In 2004, Lynch was appointed president of Cigna Dental. The following year, she was named to a newly-created position that combines leadership of Cigna Group Insurance and Cigna Dental. She left Cigna in 2009 to become president of Magellan Health Services.
