San Diego's oldest Unitarian Universalist congregation, meeting continuously since Unitarians first gathered at Horton Hall in 1873, First Unitarian Universalist Church of San Diego - Hillcrest occupies a campus accessible via 298 W Arbor Dr in the 92103 ZIP code. The church's social justice programming connects directly with neighborhood organizations such as Alpha Project For the Homeless, extending its outreach beyond the sanctuary. Affiliated with the Unitarian Universalist Association, the congregation draws from Jewish, Christian, Buddhist, humanist, and earth-centered wisdom traditions rather than a single creed. Community arts partnerships include collaboration with ArtReach San Diego, reflecting the church's integration of creative expression into its worship and education calendar. The church operates a two-campus model spanning its Hillcrest headquarters and a South Bay satellite, coordinating multi-site worship, religious education, and social justice campaigns across both locations.
