Hospice Program

The CMC is the second institution in the California Department of Corrections and Rehabilitation to offer a hospice program to the inmate population. The program has trained over 100 inmate volunteers since its inception at CMC in 2001.  There are currently 61 volunteer inmates who have completed the training program and are available to visit terminally ill inmates that are housed in the institution hospital. These volunteers are also available to the general population inmates during a monthly memorial service to assist them in their grief of family members who have passed while incarcerated.  The training was developed and presented by local hospice staff, to closely match training offered to volunteers within the community. According to volunteer inmates and inmate recipients of hospice care, the program is of great value on both sides of this very critical issue.

DRP Programs

CDCR’s Division of Rehabilitative Programs offers a wide range of programs for inmates. Check to see which programs are offered at this institution.

California’s Central Coast has been described as a hidden jewel in the Golden State. In fact San Luis Obispo, in published reports, has been called one of America’s happiest/healthiest/friendliest cities with the best downtown and best college towns (Cal-Poly San Luis Obispo). Two local landmarks are among the most popular destinations. The Madonna Inn is famously eccentric with 110 rooms with names such as Antique Cars, Yosemite Rock, and Caveman. Nearby is the world renowned Hearst Castle which was built between 1919 and 1947 for newspaper magnate William Randolph Hearst. The 90,000 square foot castle sits on the 250,000 acre Hearst Ranch, atop a hill of the Santa Lucia Mountain Range. There are mountains and peaks throughout the San Luis Obispo area that provide countless hiking and biking trails, outdoor activities and adventures. If you love the beach, there’s Pismo, Avila and Morro Bay nearby for a day of sun, sand and fun.

CMC is comprised of two physically separated complexes commonly referred to as “East Facility” and “West Facility”.

East Facility is a Level III complex divided into five independent facilities (A, B, C, D and H.) Facilities A through D house medium-security, Non-Designated Programming Facility inmates while providing Enhanced Outpatient Program (EOP) and Correctional Clinical Case Management System (CCCMS) levels of care to qualifying inmates. East Facility also provides housing and programs for inmates with developmental disabilities and those who need assistance with activities of daily living. Each Facility has two, three-story housing units, with all inmates housed within cells. Dozens of classrooms, counselling offices and vocational shops are available throughout East Facility in order to offer a myriad of educational and self-help programs to the inmate population.

East Facility also contains a Correctional Treatment Center – Medical Unit that provides a hospital-ward treatment environment for CDCR inmates from around the state.

Facility H is a stand-alone, 50-bed Mental Health Crisis Bed Unit that opened on August 27, 2013. Facility H provides 24-hour/day mental health treatment and monitoring for the inmates housed therein.

West Facility is a Level I and II complex that is divided into four independent facilities (E, F, G, and M.) West Facility houses medium and minimum-security, Non-Designated Programming Facility inmates in a dormitory setting. West Facility also provides CCCMS care for qualifying inmates. Facility M houses inmate firefighters who work with Cal-Fire Captains to fight wildfires and respond to natural disasters around California. Facility G is home to the New Life K9 Program, which trains service dogs to assist first responders who suffer from Post-Traumatic Stress Disorder and other physical disabilities. West Facility inmates have the opportunity to take advantage of increased academic and career/technical education, as well as self-improvement programs including: cognitive behavior therapy programs, substance abuse education, criminal thinking, anger management and family relationships.

CMC is committed to providing its inmate population with meaningful rehabilitative resources in order to ensure the men who are released from CMC have the opportunity to rejoin society as peaceful, productive citizens.

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.
