About the Foundation

Guided by the belief that every life has equal value, the Bill and Melinda Gates Foundation aspires to help all people lead healthy, productive lives. We are dedicated to discovering and disseminating innovative approaches to addressing extreme poverty and poor health in developing countries and improving the U.S. education system. Because our financial resources, while siginificant, represent a small fraction of what’s needed to address these challenges, we work in partnership with governments, the private sector, and other donors and organizations to achieve the greatest possible impact. www.gatesfoundation.org
