An Interview With Madeline Kerner, National Director of Outreach and Development, Peer Health Exchange

As the curriculum in many public high schools becomes more focused, it drives some subjects to the periphery. In 2003, Peer Health Exchange formed to help some schools reintroduce health education to the classroom.

Now based in San Francisco and working with a 2010-2011 annual operating budget of more than $3.4 million, the organization's efforts help educate thousands of high-school students.
