Mark Bertolini, CEO, Oscar Health; Chairman, Verizon

Mark’s long journey in the health care industry has been both professional and personal—highlighted by his son’s intense battle with cancer in the early 2000s. In a story spanning a fateful day on a snowy mountain, a desperate plea in an empty chapel, and an investor meeting gone wrong, it’s the kind of tale that feels straight out of a Martin Scorsese film. Mark’s journey of personal and professional redemption is a reflection of the tragedies, tradeoffs, and triumphs that have shaped him. But as he explains it, life-or-death moments provide a reminder that life isn’t easily separated into work and home—and the leaders who stand to benefit the most are the ones who embrace the mystery of it all.
