Mission Trails Church in Allied Gardens, San Diego started in a home in 2008 and now occupies the former Zion Avenue Community Church campus at 4880 Zion Ave after the two congregations merged in June 2015. The Southern Baptist church, affiliated with the San Diego Southern Baptist Association, draws members from Allied Gardens, San Carlos, Del Cerro, Grantville, Santee, and Fletcher Hills across the 92120 ZIP and surrounding east-county communities. Two services run each week at the Zion Avenue campus, and families with school-age children in the congregation feed into Patrick Henry High School less than a mile south on the Allied Gardens residential grid. The church's mission framework centers on three verbs—making, maturing, and multiplying followers—with small-group discipleship tracks running alongside the main teaching calendar. Waring Road and Zion Avenue anchor the Allied Gardens commercial pocket where the church sits, near the Kaiser Permanente Zion Medical Center that marks the neighborhood's health-services hub. Childcare for the youngest attendees during services connects to the same family-care network that feeds Sagebrush Children's Center on the Allied Gardens side of the 92120 ZIP for weekday enrollment. The 2008-to-present growth arc—from a living-room gathering to a merged campus with two weekly services—tracks a pattern of residential-neighborhood church planting that has become the Southern Baptist Convention's primary expansion model in suburban San Diego.
