Chris Calbert

Chief Administrative Officer

Email 225-654-0287

Chris Calbert serves as the Zachary’s Chief Administrative Officer. His public service career spans five decades.  He began working at the Baton Rouge Police Department in August 1968. He served as a member of the City’s first Arson Task Force, later led its Rescue Squad, and established the Department’s Arson and Explosives Unit. He also assisted in the development of its Tactical Team, serving as an active member throughout his career. He co-authored the City’s “All-Hazard’s Emergency Plan” and retired as the Commander of the Department’s Uniform Patrol Division in 1996. A four-year administrative post with the Sheriff’s Office in Pointe Coupee Parish would also follow. During a career punctuated by specialized training, each new opportunity would prove beneficial to the successful career track he would take.

An early career opportunity involved training international police officers through the U.S. State Department’s “Anti-Terrorism Assistance Program”. Other opportunities would follow with Calbert becoming a consulting professional for the Department of Justice following the Oklahoma City Bombing, when he co-authored an LSU training initiative for law enforcement first responders titled, “Terrorism: Basic Concepts”.

Following the attacks of 9/11, he would co-author other sensitive training initiatives for both DOJ and later DHS at New Mexico Tech, in Socorro, N.M. He would become a DHS Senior Instructor assigned to the University’s “Energetic Materials, Research and Testing Center”. There, over the next eleven years he would instruct more than 5000 first response “trainers” from across the country.

During his tenure in New Mexico, he was also assigned to the International Law Enforcement Academy in Roswell, where he taught police administrator’s from around the world. The Academy; a U. S. State Department “Bureau of Diplomatic Security” initiative, taught protective measures of American assets and interests abroad.

Calbert worked on government projects for many years with the same Washington, DC based defense contractor whose corporate mantra was strictly business oriented. While it’s applicability within the public service arena did not fit; the knowledge he acquired as a consultant, technical writer, and special projects developer did. All those skills would be utilized in his role with the City of Zachary.
