It is the mission of the T.H. Pendergast California Parole Museum to collect and organize artifacts that document the history of parole in California. The preservation of parole history honors and unites those who have worked for or been served by the California Parole System and is intended to be a source of pride and identity.

Educational Resource

The collection will serve the community as an educational resource by creating interactive projects and mobile exhibitions. Educational partnerships will be fostered to generate scholarly research.

The museum will also serve to educate the public by bringing to the community carefully developed exhibits that instruct, inspire and lead to a better understanding of the parole mission, history and future of California.
