4-H in San Mateo & San Francisco Counties

What is 4-H?

The University of California 4-H Youth Development Program serves youth and teens in 57 of 58 California counties through traditional clubs, after-school programs, state-wide leadership conferences and camps.
As the largest, non-profit youth organization in the country, 4-H has a proven history of making lasting change in the lives of young people. At 4-H (Head, Heart, Health, Hands), your child will build positive, healthy relationships, learn invaluable life skills, and grow into a competent, caring citizen. 4-H’ers are actively engaged in their communities and our programs develop strong future leaders.
Through hands-on learning, youth-adult partnerships, and research-based educational programs, youth enhance their leadership abilities and develop a wide range of skills. Our programs focus on four focus areas: STEM (Science, Technology, Engineering, Mathematics), Healthy Living, Civic Engagement, and Leadership.
