Established in 1956, Lakeside Christian Church has rooted itself on El Monte Road as one of the longest-running congregations in Lakeside. The church's children's ministry runs a dedicated Kids Church track during both worship gatherings, complementing the early-childhood programming provided by church-based centers such as Lakeside Presbyterian Preschool on nearby Channel Road. A purpose-built sanctuary seating approximately 300 replaced the original structure and added a modern audio-visual system for simultaneous livestreaming to Facebook and YouTube audiences. Youth programming includes a separate student-led worship gathering with its own teaching rotation, extending the church's reach along the Lake Jennings and El Monte corridor through small-group home studies scattered across the 92040 ZIP code. That neighborhood-level outreach dovetails with the social services provided by Lakeside Christian Helps Center, which distributes food and emergency aid from Channel Road. Affiliated with the Christian Churches and Churches of Christ movement, the congregation maintains an expository teaching format rooted in New Testament restoration principles.
