Population Services International

PSI is a nonprofit organization based in Washington, D.C. that harnesses the vitality of the private sector to address the health problems of low-income and vulnerable populations in more than 60 developing countries. With programs in malaria, reproductive health, child survival and HIV, PSI promotes products, services and healthy behavior that enable low-income and vulnerable people to lead healthier lives. Products and services are sold at subsidized prices rather than given away in order to motivate commercial sector involvement.
