The Coalition was founded in 1986 in response to California’s growing need for a formally structured resource for professionals working with persons involved in the commission of rape, child sexual abuse, incest, and other forms of sexual assault.

Coalition members represent law enforcement, criminal justice, mental health, probation, parole, and other community services. Members are dedicated to addressing complex issues related to sex crimes and sexual deviance.
