The mission of Guardians of The City (GOTC) is to preserve the heritage and to record the history of Emergency Medical Services (EMS), the San Francisco Fire Department (SFFD), the San Francisco Police Department (SFPD) and the Sheriff's Department for the benefit of the citizens of San Francisco and beyond.  The GOTC represents these entities through training and education at community events, parades, and public displays with the artifacts and equipment of the collection.

This mission will include the conservation and preservation of the collection, which includes photographs, documents, graphic items, memorabilia, apparatus, appliances and other artifacts at a future GOTC Museum. We preserve our history to learn from our mistakes and build upon our successes.

The GOTC Memorial honors those members who have fallen in the line of duty that their memory may not be forgotten.
