St. Andrew's Episcopal Church in La Mesa has anchored the Glen Street block since 1948, when the congregation moved from its original 1924 chapel at Lemon Avenue and Spring Street near the heart of La Mesa Village. The church has operated St. Andrew's Parish Day School since 1947 on the shared campus, making it one of La Mesa's longest-running faith-based early-childhood programs. Worship follows the Rite II Holy Eucharist from the Book of Common Prayer, blending Episcopal liturgical tradition with a praise band and organ-accompanied hymns in a single Sunday service. Community engagement includes the Sacred Ground initiative—facilitated dialogues on racial healing under the Episcopal Church's Becoming Beloved Community framework—and neighborhood connections with civic venues like the La Mesa Community Center. The sanctuary maintains a traditional Episcopal chancel with altar rail and reredos, and the courtyard's drought-tolerant landscape—recognized by La Mesa Beautiful—creates an outdoor event footprint beneath a heritage California pepper tree.
