Population Media Center's founder and president, William Ryerson has a 37-year history of working in the field of reproductive health. This includes 20 years of experience adapting the Sabido methodology, a family planning communication model, to various cultural settings worldwide. He has also been involved in the design of research to measure the effects of such projects in a number of countries. This has led to a series of publications regarding a serialized radio drama in Tanzania and its effects on HIV/AIDS avoidance and family planning use.
He received a BA from Amherst College and an MPhil from Yale University. He served as director of the Population Institute's Youth and Student Division, development director of Planned Parenthood Southeastern Pennsylvania, associate director of Planned Parenthood of Northern New England and executive vice president of Population Communications International before founding Population Media Center.

Ryerson is listed in several editions of Who's Who in the World, Who's Who in America and Who's Who in the East. In 2006 he was awarded the Nafis Sadik Prize for Courage from the Rotarian Action Group on Population and Development.
