Founded by singer/songwriter Paul Simon and pediatrician/child advocate Irwin Redlener, MD in 1987, The Children's Health Fund (CHF) works nationally to develop health care programs for the nation's most medically underserved population - homeless and disadvantaged children. CHF brings medical care and essential services directly to underserved children in rural and urban communities via Mobile Medical clinics (doctor's offices on wheels) and fixed site clinics. Moreover, CHF has become a major national advocacy voice on behalf of all children, and has inspired special federal legislation designed to help create innovative Children's Health Projects throughout the United States. The Children's Health Fund's website contains a lot of useful information, which would undoubtedly benefit your audience.
