The SFHAC Staff

Tim Colen has been SFHAC's Executive Director since August 2005. Prior to this, he spent many years as a part-time and full-time neighborhood activist, primarily on urban environmental and land use issues on the City’s west side. Mr. Colen was President for three years of the Greater West Portal Neighborhood Association, a 400-member group. He was also a founding member, and later Chair, of the Lake Merced Task Force, a 40-member umbrella coalition dedicated to restoration and maintenance of Lake Merced. In addition, Mr. Colen has worked extensively for many years in San Francisco political campaigns.

Mr. Colen is a geologist by training and spent 25 years working in project management with mining and environmental consulting firms. Much of this experience was international. He graduated with a BS in Earth Science from UC Santa Cruz, MS in Mining Engineering from Columbia University, and a Certificate in Hazardous Materials Management from UC Berkeley. He lives with his family in the West Portal district.

Julia Sullivan is SFHAC's Program Manager. Before joining SFHAC, she worked on various political and environmental advocacy campaigns and did policy research work. She graduated with a BA in Economics from UC Santa Cruz and has a Masters in Public Policy from Cal Poly, San Luis Obispo. She sees housing as an important policy and social justice issue and is proud to be supporting SFHAC's mission. Julia spends time outside of work on her masters swim team and hiking throughout the Bay Area.
