Gang Reduction Initiative of Denver

The Gang Reduction of Denver (GRID) is a network of federal, state, and local government agencies; local businesses; community-based, grassroots and faith-based organizations; and community resident associations that work in a collaborative manner to address gang violence. GRID is housed under the Denver Department of Public Safety and is committed to the suppression and prevention of gun and gang violence in Denver. This is achieved through several strategies including connecting resources within communities, enhancing information sharing and collaboration among agencies, and seeking change in community norms regarding violence.   

GRID works to develop and support a network of partner agencies and programs to provide effective and efficient prevention strategies that collectively strengthen families and communities, provide effective and efficient case management intervention strategies to high-risk gang members and their families, and ensure effective enforcement of violent gang crimes. 

GRID operates under the strategic direction of a committee working together to facilitate any necessary policy action and address the removal of barriers to support implementation efforts. The GRID Policy Steering Committee is responsible to ensure the integrity of the project by monitoring accountability, transparency, sustainability, and public trust.

GRID offers several trainings for agencies and organizations working with gang individuals. Following is a list of GRID's standard training series presentations:

  • GRID General Overview Training: The GRID model consists of 24 coordinated strategies. This training will provide a through description of our prevention, intervention, and enforcement-based strategies to reduce violent crime in Denver neighborhoods, achieve positive behavior changes in those receiving gang services, increase collaboration among network partners, and change community norms regarding gang and gun violence. We will also discuss how understanding gang violence and the role violence plays in gangs are essential to prevention and suppression efforts.
  • Introduction to Gangs: This training provides a basic, introductory overview of the gang lifestyle. Topics include the difference between a group vs. a gang, street gangs vs. prison gangs, risk factors for joining a gang, the appeal of the gang lifestyle, and common identifiers of gang members. It is recommended for professionals in the school system, working with youth, or anyone seeking to become more familiar with gang basics. Strategies for prevention, intervention, and gang disengagement will also be covered. This course is an excellent start for anyone interested in continuing with GRID’s Gang Training Series.
  • Gang Structures and Dynamics: Gang structures and dynamics are constantly changing and vary within different gangs as well as among different gang sets within a specific gang. In order to effectively work with gang members, agencies must develop and understanding of gangs, their origins, alliances, conflicts and criminal activity. It is also critical to stay current in emerging trends and patterns. This training will provide an intensive overview and detail of the history, structures, and dynamics of each Denver-based gangs to include key members, enemies, and known criminal activity. Presenters will also provide an overview on new hybrid gangs, emerging from the more well known Denver gangs.  Attendees will leave with a deeper understanding of the dynamics of each group discussed. This training is regularly taught with partners from the Colorado Department of Corrections and Denver Sheriff’s Office. It is recommended for the professional with a more advanced level of gang knowledge.
  • Understanding Gang Structures and Dynamics for Effective Intervention: This presentation builds on the Gang Structures and Dynamics training to assist professionals providing case management services to this population. Attendees will leave with a deeper understanding of Denver gangs and get caught up on emerging trends and patterns, as well as tips for case planning, monitoring gang behaviors, and assessing an individual’s social commitment to the gang. We will also discuss our Intervention Support Team model, which is a coordinated case management approach to gang intervention.
  • Girls in Gangs: The role of females in gangs is often misunderstood and minimized by criminal justice agencies, as they are typically not viewed as dangerous or prevalent in numbers. In addition, the reasons and risk factors for joining a gang and the negative impact gang involvement have on girls and women differ from their male counterparts. This training will provide an overview of the history, perceptions, the risk factors for joining and for victimization once they are part of a gang, and the appeal to gangs.
  • Outreach Work Best Practices: Gang outreach workers have a very unique job, not only by the population they serve, but by the vast range of roles they serve in their day-to-day jobs. Outreach workers engage clients and serve a mentoring role, they are systems navigators for individuals in need of assistance from social service agencies, often advocating for their clients. They often provide crisis response directly to gang members and their families after a shooting or homicide, and they regularly keep outside agencies informed of gang activities and trends in the area. They must be able to serve as a model for pro-social behavior, have strong relationship building skills, possess a deep understanding of gang dynamics in the city they work, and be able to build a level of trust with clients and the community. This training provides insight into the role of the gang outreach worker and their responsibilities. It is taught by GRID outreach workers with several years of experience serving in this role. They will discuss challenges and barriers to their efforts as well as what the ideal characteristics all outreach workers should have. This training is recommended for anyone who is in the field, providing direct services to this population.
  • Additional training opportunities: In addition to our standard training series above, GRID sponsors several trainings conducted by law enforcement and community organizations as we realize there are many more gang-related topics covering mental health, gangs in schools, specific gang history, etc. We will send out information on GRID sponsored trainings as they are scheduled. If you need any specific gang or gang program-related topics that are not covered in the above training descriptions, please contact us to discuss your training needs as we will more than likely be able to tailor a presentation to your agency’s needs.
