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 has two physically separated housing complexes, commonly referred to as “East” and “West”. An emphasis is placed on providing all inmates with programs for self-improvement. These programs include academic and vocational education, work skills in prison industries and inmate self-help group activities.

The Level III housing complex (East), which houses medium security general population inmates, is divided into four Facilities. Each Facility has its own dining room, classrooms, athletic fields, and two three-story housing units. The East housing complex has a fully licensed General Acute Care Hospital and provides a full range of medical services for the Department of Corrections and Rehabilitation. The facility also provides a Mental Health Delivery System in the form of an Enhanced Outpatient Program and Outpatient treatment for inmates assigned to the Correctional Clinical Case Management System, as well as a new fully licensed 50 bed Mental Health Crisis Unit.

The Level I and II housing complex (West) houses minimum security general population inmates in dormitory settings within three separate facilities. In addition, the West housing complex contains a Level I camp program for fire suppression, conservation and other community service work. CMC works extensively within San Luis Obispo County, in conjunction with other governmental entities, through Community Service Crews which perform many valuable services to the various communities within the county. CMC’s West Facility has been designated as a re-entry hub. As part of the re-entry hub program, inmates are given the opportunity to take advantage of increased academic education and increased career technical education. CMC West inmates have access to cognitive behavior therapy programs such as substance abuse, criminal thinking, anger management and family relationships. Additionally, CMC West inmates may also take advantage to transitional programs that help them get jobs, plan out a career path, plan for their financial future and obtain a California ID card before their release.

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.
