South Bay Community Services — now operating as SBCS — has anchored Chula Vista's social-service infrastructure from its Fourth Avenue headquarters since 1971, when it launched as a teen drug-counseling drop-in center called Our House. The agency's youth-development pipeline connects adolescents to post-secondary pathways across the South Bay, including institutions in the same regional education corridor as Southwestern College. With EIN 95-2693142 and roughly 500 staff deployed across schools, police substations, family resource centers, and subsidized-housing sites, SBCS delivers mental-health counseling, domestic-violence intervention, and housing-navigation services to more than 50,000 individuals per year. The organization completed a $34 million Center for Impact on Fourth Avenue in 2025, consolidating operations into a single campus capable of serving 60,000 people annually. Behavioral-health referrals flow through a network that includes Community Health Group, aligning SBCS's counseling programs with federally qualified health-center coverage for Medi-Cal enrollees and individuals without commercial coverage. The Center for Impact's clinical wing houses dedicated child-welfare suites, a bilingual Mi Escuelita preschool for children affected by domestic violence, and a crisis hotline reachable at 800-640-2933.
