More about the Regional Assistant Commissioners

Regional Assistant Commissioners serve as liaisons between CDA, their communities, and agricultural communities across the state. 

These part-time, remote positions make it more feasible for working farmers and ranchers to be part of the CDA team. The Regional Assistant Commissioners further the Department's efforts in cultivating relationships with local agricultural communities by sharing the Department’s priorities and available resources, helping guide CDA’s work to advance and support agriculture based on direct community input, and by creating a direct connection between rural communities and CDA.
