An online lecture and in-depth discussion with Rosanne Haggerty

Friday, December 2 at 6pm EST


Rosanne Haggerty has been working with others to end homelessness since 1990. While her goals were ambitious, creating nearly 3000 affordable homes in New York City and then galvanizing communities throughout the country to house 100,000 chronically homeless people during a four-year campaign, she came to realize that a more systemic approach was required. The result was the goal of “Functional Zero,” which is being successfully implemented in more than 140 communities in the US and internationally. Rosanne will review the evolution of her approach to ending homelessness–and what the future will bring with the recent award of the MacArthur Foundation’s “100 & Change” grant


Rosanne Haggerty is a graduate of Amherst College and Columbia University’s Graduate School of Architecture. Her work through her organizations Common Ground Community and Community Solutions has been internationally recognized, including the Jane Jacobs Medal for New Ideas and Activism from the Rockefeller Foundation and the Social Entrepreneur of the Year from the Schwab Foundation.
