As an advocate for social change, California Partnership to End Domestic Violence’s (CPEDV) prevention strategy is to promote respectful and equitable nonviolent relationships through individual-, relationship-, community-, and societal-level change. The Centers for Disease Control and Prevention (CDC) funds CPEDV which, in turn, provides funding and support for four local California communities to prevent and respond to intimate partner violence within their community. All four local coordinated community response teams (CCRs) focused efforts, in part, on preventing and addressing the impact of domestic violence on children and/or youth. Using a combination of one-on-one coaching, training, evaluation design, and analysis, Korwin Consulting built CPEDV and their prevention partners’ capacity to evaluate, strengthen, and sustain their prevention efforts.
