Additionally, Dan brings expertise and values that are aligned with our organization, and I, along with Gilead’s entire Board, am confident in his ability to work alongside our talented leadership team and deliver on our ambitious goals.”

The company has successfully grown into a global organization, providing access to people around the world, while maintaining its focus on innovative science,” said O’Day. “Together with the Board, leadership team and Gilead’s 11,000 employees, I look forward to building on this in ways that I believe will – in keeping with Gilead’s mission – transform the lives of millions of individuals.”
