What is Cooperative Extension?

The University of California Cooperative Extension (UCCE) Offices are local problem-solving centers, part of a statewide network of UC researchers and educators who bridge UC research with the communities we serve. Our Advisors and Community Education Specialists deliver a range of locally relevant programs focusing on farm, environment, nutrition, 4-H youth development, science literacy, urban agriculture, home and commercial horticulture. We deliver science-based information through public workshops, meetings, newsletters, and mass media communication tools to local communities. In addition, our Advisors and Community Educator Specialists collaborate on partnerships with government agencies and community-based organizations to extend the reach of our programs

UC Cooperative Extension has been serving San Mateo County since 1945 and San Francisco County since 1970. The San Mateo/San Francisco County UCCE office is unique with the addition of the Elkus Ranch Environmental Center, we teach thousands of school aged children in the San Francisco Bay Area environmental education in a rural setting, thus creating a sense of stewardship to the environment. 

Local Cooperative Extension services are provided at our office located at UC Elkus Ranch just south of Half Moon Bay.  Housed there are program offices for 4-H, Environmental Horticulture and Urban Forestry, the Master Food Preserver and Master Gardener Programs. Our Nutrition Program and staff are located at an secondary location in South San Francisco.
