The Commission

The Commission

The Act requires each county in California to establish a Commission to oversee the implementation of the Act. The San Joaquin County Board of Supervisors adopted an ordinance creating the San Joaquin County Children and Families Commission. The Board then appointed the Commissioners to serve on the Commission. In August 2003, the Children and Families Commission officially adopted First 5 as the Overarching Program Identity.

A nine member volunteer commission oversees the work of First 5 San Joaquin, which supports the health, development and well-being of our youngest children through their first five years. Commissioners are selected and appointed by the San Joaquin County Board of Supervisors and includes representatives from the Board of Supervisors, County departments, and individuals who have an expertise in serving children and families.

Executive Director, A+

Susan de Polo, Commissioner

Susan was born, raised, educated and lives in San Joaquin County. During the years she raised her three children she was a "stay at home" mom and community activist/ volunteer. She was extremely active in education and the non-profit worlds serving on multiple boards of directors, and founding new organizations. Her criteria for choosing a group to support was that its outcomes helped children.

Since 1986 she has been the director of an educational foundation. The mission of the foundation was the enhancement of public education in San Joaquin County. A ten day tobacco education and prevention curriculum, "Keys to Success and Good Health" was their first school based program for the county.

San Joaquin A+, founded in 1996, is a collaborative organization that supports and enhances the education of youth in order to create responsible, employable and productive citizens by identifying and engaging in methods of cooperation and collaboration among education, business and community based resources of our county.

When organizing an action group to make sure that all children in San Joaquin County will start school "ready to learn" it became evident that healthy families must be a part of the equation. The goals of this group are the same as the goals of proposition 10. When a seat on the newly established commission opened she felt her skills, knowledge and links to business, non-profits, schools and the community would be an asset. She feels it is an honor to serve on this commission and that her skills as a facilitator and consensus builder will help the progress of this group. She continues to serve on multiple boards of directors and advisory boards both on the state and local levels. The Act requires each county in California to establish a Commission to oversee the implementation of the Act. The San Joaquin County Board of Supervisors adopted an ordinance creating the San Joaquin County Children and Families Commission. The Board then appointed the Commissioners to serve on the Commission. In August 2003, the Children and Families Commission officially adopted First 5 as the Overarching Program Identity.
