PSI makes it easier for people in the developing world to lead healthier lives and plan families they desire by marketing affordable products and services. PSI's global health network of more than 50 local organizations focuses on serious challenges like a lack of family planning, HIV and AIDS, barriers to maternal health, and the greatest threats to children under five, including malaria, diarrhea, pneumonia and malnutrition.

A hallmark of PSI is a commitment to the principle that health services and products are most effective when they are accompanied by robust communications and distribution efforts that help ensure wide acceptance and proper use.

PSI works in partnership with local governments, ministries of health and local organizations to create health solutions that are built to last.
