Program Information

Gilliam Youth Services Center opened in April of 1903 and is the oldest state operated detention center in Colorado. The program serves up to sixty-four youth, both male and female, from the 2nd Judicial District located in the city and county of Denver. Gilliam is secure detention holding for youth from ages 10 to their 18th birthday. 

Gilliam Youth Services Center personnel are committed to modeling excellence. Through restorative principles, we teach youth to become responsible, productive citizens while keeping the community safe. Youth receive a minimum of 14 hours of programming per day Monday through Friday, and 12 hours of programming per day on weekends and holidays. All youth are given the opportunity to attend weekly religious services and are granted one hour of recreation daily.

There are four levels in Gilliam’s behavioral management program which are a way of marking achievement and responsibility. As a youth advances through the levels, his/her responsibilities and privileges increase. If rules are followed, a youth will advance through the level system. With positive behavior, youth may gain expanded privileges. Privileges are typically tied to bedtime, allowable items in the youth’s room, number of phone calls home or number of visits to enumerate a few.

Gilliam is a Denver Public School site. Monday-Friday students attend classes promoting progress in the academic areas of reading, writing, mathematics, social studies, computer technology and physical education. In addition to the academic progress that students will make while placed at Gilliam Youth Services Center, students will progress in their ability to handle a wide variety of social/emotional issues and situations in a healthy way. Qualifying students are able to participate in the school’s GED program.

Gilliam continues to host the Denver Collaborative Partnership meetings as it has done for the past five years. This allows professionals from the various community agencies and disciplines the opportunity to come together and discuss interventions and services that could be implemented in lieu of commitment to the Division of Youth Corrections.
