As of June 2021, the organization has nine communities with active volunteers,[2] including Boston, New York City, Chicago, Los Angeles, San Francisco Bay Area, Denver, Dallas, Detroit and Stockton.

Their goal is to prevent growing trends in adolescents engaging in risky or harmful behavior in sexual and personal spheres of their lives.

In 1999, six graduates from Yale University began going into underfunded and understaffed public high schools in New Haven, Connecticut, to teach health workshops.

They are often students including public service in many areas of their life and 90% of past volunteers express that PHE affected their career goals after college.

The volunteers speak to the students in ways relevant to their everyday lives and can serve as role models demonstrating healthy behavior.

Part of the PHE curriculum is to help the students practice their communication skills as well as risk evaluation, prevention, decision-making through role-playing resembling true to life situations.
