History
CIM opened in San Bernardino County in 1941 on 1,700 acres of land. The California Institution for Men (CIM) is a large complex consisting of four separate facilities under the administration of one warden.
Dedicated on June 21, 1941, the California Institution for Men was the first major minimum security institution built and operated in the United States. It was the State of California’s third correctional institution and was constructed to relieve the overcrowded conditions of San Quentin State Prison (1852) and Folsom State Prison (1881).
CIM was unique in the field of penology because it was known as the “prison without walls.” The only “security” fence around the facility units was a five-strand barbwire livestock fence, intended mainly to keep the dairy cows from wandering through the living areas.
CIM has since increased security to meet the challenges a vastly different inmate population requires. While no longer known as “the prison without walls” CIM’s Secure Level I Facility A houses the largest Level I inmate population within the California prison system. The CIM I Facility can house approximately 2,000 minimum custody level inmates at the facility.
In additional to the CIM I Facility, CIM’s operation includes one reception center, Facility B Reception Center (1951). In August 2010, CIM converted the former Reception Center West facility to a mainline facility known as Facility A, which houses custody level II non-designated programming inmate population. In December 2012 CIM converted Reception Center East facility to a mainline facility known as Facility C. This facility houses custody level-II non-designated programming inmate population.

In March 2014, he promoted to Captain at CIM and three years later, promoted to Associate Warden at Ironwood State Prison (ISP). In September 2021, Merchant accepted the Chief Deputy Warden position at ISP.

Warden Merchant’s priorities are to support CDCR’s vision and mission, with emphasis on rehabilitative and restorative justice programs while exemplifying the Department’s values of service, leadership, integrity, accountability, respect, trust, and collaboration.

Local Inmate Family Councils (IFC’s) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC’s promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues. For more information on connecting with a local IFC, please visit the Statewide IFC website.
