When you're CEO of the nation's largest health insurance company, your words can shape indusrty trends. As the U.S. Supreme Court was considering overturning the Affordable Care Act, Hemsley announced that UnitedHealth would honor some of the law's provisions regardless of the justices' decision. Other major insurers followed suit. Through the law stood, it's one example of Hemsley using his influence on behalf of UnitedHealth. Lately Hemsley guided the company through the implementation of Obamacare, and the repair of the site, while beating Wall Street epectations, attracting 10 million more members and growing revenue 12 percent to $30.4 billion.
