Oscar Health CEO Mark Bertolini Aims to Reform Healthcare System

Mark Bertolini, CEO of Oscar Health, who previously led Aetna and Bridgewater, is now focused on reforming the U.S. healthcare system. Bertolini joined Oscar Health as CEO in 2023, citing an opportunity to improve access to and affordability of health insurance.

The company, founded in 2012 by Joshua Kushner, Kevin Nazemi, and Mario Schlosser, builds provider networks tailored to local communities, diverging from legacy insurers that use broad commercial networks. Bertolini suggests this strategy, combined with a technology-first approach, yields better cost control and customer care.

Oscar Health has recently invested in technological advancements. Last year, the company introduced Oswell, an AI health assistant designed to help patients with medication tracking and answer health-related questions. In August 2024, Oscar launched Lucie Health Marketplace, a platform Bertolini has referred to as "Airbnb for healthcare."

Under Bertolini's tenure, Oscar Health's membership has grown from approximately 1 million to 3 million. The company reported a 53% increase in first-quarter revenue to $4.6 billion and affirmed its expectation of profitability in 2026. It has responded to the expiration of Affordable Care Act subsidies by launching new low-cost products for the 2026 open enrollment period.
