Trauma Prevention Initiative

Trauma Prevention Initiative

The Los Angeles County Department of Public Health, Office of Violence Prevention partners with community residents and stakeholders to implement the Trauma Prevention Initiative (TPI) to reduce violence-related injuries and deaths. Launched in 2015, TPI aligns County services and initiatives to build a comprehensive, place-based approach through innovative programs, policies, and partnerships. TPI supports a community-driven approach to public safety that is survivor centered, and empowers community leadership, coordinating across sectors to build infrastructure for prevention and well-being in the county’s highest need communities.

TPI was initially focused on South Los Angeles, on July 13, 2021, the LA County Board of Supervisors approved a motion to expand TPI, including enhanced services in the current four South Los Angeles communities, and adding five new communities. These communities were identified based on an analysis of crime data, homicide data, poverty, and recent increases in violence.

OVP is grateful for the support of the Board of Supervisors for expanding community-driven public safety in the County. This would not have occurred without the support of our many county and community partners who have made this work happen and advocate for it to expand, including the leadership of our Community Action for Peace networks, and the intervention workers who risk their lives daily to promote peace in their communities.
