In recent years, following a near-death experience, Mr. Bertolini set about overhauling his own health regimen, as well reshaping the culture of Aetna with a series of eyebrow-raising moves. He has offered free yoga and meditation classes to Aetna employees; more than 13,000 workers have participated. He began selling the same classes to the businesses that contract with Aetna for their health insurance. And in January, after reading “Capital in the Twenty-First Century,” the treatise on inequality by the French economist Thomas Piketty, Mr. Bertolini gave his lowest-paid employees a 33 percent raise.
Taken together, these moves have transformed a stodgy insurance company into one of the most progressive actors in corporate America. Most health insurance companies are thriving, largely because of increased enrollment. Aetna’s stock has increased threefold since Mr. Bertolini took over as chief executive in 2010, and recently hit a record high. It’s a decidedly groovy moment for the company, and Mr. Bertolini is reveling in his role as an idealistic, unconventional corporate chieftain.
