When I joined Pfizer in 2008, a lot of people asked me, 'Why this?' 'Why now?' The answer, most fundamentally, is that I believe in Pfizer. What we are doing is mission-critical. The opportunity to be more intimately involved in sorting out health care solutions is compelling. The collaborative work we do is a big draw. We are direct and, most important, unafraid to see things as they are, and not as we wish that they were. That is the only way we will be able to deliver on our commitments to the people who depend on us."
