4-H Regions

The University of California 4-H Program is in every county in California. The counties are grouped into 12 regions. Each region has a Regional Program Coordinator.

Regional Program Coordinators lead and support the 4-H Community Education Specialists in their region. They also provide training for staff and volunteers.

Community Education Specialists help lead 4-H programs in their county. They support young people, volunteers, and community partners. They also help more youth and families join 4-H.

4-H Academic Advisors are experts in specific content areas. They use their content expertise to study what helps young people learn and grow. Academic Advisors share what they learn with the California 4-H community through trainings, easy-to-read fact sheets, short guides, and other educational resources.
