The San Diego-Tijuana Border Initiative in Chula Vista has advanced cross-border public health policy from its Bonita Road office since 1994, when it launched as a collaborative project of the Daedalus Alliance for Environmental Education and United Way of San Diego County. The nonprofit's substance-abuse prevention and community-wellness campaigns operate across multiple South Bay ZIP codes, paralleling the holistic health programming at facilities throughout the region, SoCal Wellness among them. Under EIN 91-2146860, the organization runs four core programs: the South Region Tobacco Control Initiative, the Drug-Free Border Coalition, the Cinco de Mayo Con Orgullo Para La Familia Coalition, and the Border Health Collaborative. Policy victories include smoke-free ordinances adopted by Imperial Beach, National City, the unincorporated community of Bonita, and the Unified Port of San Diego — all achieved through multi-year advocacy coordinating residents, elected officials, and law enforcement. Binational conference programming has convened experts on maquiladora-industry health impacts and border-region risk factors, with community-outreach logistics coordinating bilingual caseworkers alongside service navigators at organizations throughout the border corridor, Infinity Tax & Immigration Services among them. The Drug-Free Border Coalition's prevention curriculum targets youth substance-abuse risk factors through evidence-based intervention protocols deployed across school districts in both San Diego County and Tijuana, Baja California.
