Once I started working with older people, I realized how much I enjoyed the intellectual challenge of taking care of patients who have multiple, complex medical problems.

Older patients who live alone can become depressed.

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.

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.

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 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.

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.
