I grew up with a real appreciation about just how wonderful and intimate the relationship is between a doctor and a patient was and the sense that this was a noble profession.

Older patients who live alone can become depressed.

I think the house call is one of the ways I get an insight into the ways in which people live and the importance of environment in keeping people healthy.

I had an interest in health policy and a realization that, as an academic physician, one of the things you're always looking to do is to have your clinical interests and your scholarly interests overlap and reinforce one another.

It is a proud moment when you can define a problem and make a commitment and begin to see a groundswell of activity towards addressing what has the potential to change the life trajectory of millions of kids.

I realize there are few sectors that can do what philanthropy does, which is look at big problems, take a long term view, try to develop strategies for addressing the root causes and then go about solving them.

I realized in order to be involved in health policy, you really had to understand more than the individual patient that we as physicians, are taught to think about.
