Since co-founding Oscar in 2012, Mario has led the company in making great progress against our mission of making a healthier life accessible and affordable for all. After eight years of selling health insurance, Oscar has earned industry-leading levels of trust, engagement, and customer satisfaction from 529,000 members who, as of January 31, 2021, have chosen Oscar.

Under Mario's leadership, Oscar develops seamless technology and provides personalized support to help members navigate their health care. The company has been recognized as one of Fast Company’s most innovative companies in health, one of CNBC’s top 50 disruptors, and one of TIME’s most influential in health care.

We didn't start Oscar because we liked health insurance. Quite the opposite.
