Continuing mobile care for Katrina's children.

About the author: I am a community pediatrician and since January 2006 have served as chief medical officer of Children’s Health Fund (CHF), a national not-for-profit organization based in New York that supports a national network of 24 programs that provide comprehensive health care services to medically high-risk children and families. Patients served include the homeless, those who live in rural and urban pockets of the country that lack pediatric providers, and immigrant and postdisaster populations, who face significant barriers to health care. Previously, I served for more than 11 years as medical director of the South Florida Children’s Health Project, a CHF program in Miami-Dade County. My move from south Florida to New York was directly linked to Hurricane Katrina.
