Horizon SouthBay Church in Chula Vista maintains its administrative offices and community outreach center — known as The Door — at 49 Third Avenue, while conducting Sunday worship at a separate campus on Sweetwater Road in neighboring National City. The church's community engagement from the Third Avenue office extends into Chula Vista's civic fabric alongside service organizations such as Sweetwater Woman's Club. Founded by Norlyn Kent and now led by a second-generation pastor who previously served as a missionary in Mexico and El Salvador, the congregation follows a Calvary Chapel–affiliated verse-by-verse teaching model with both English and Spanish services. The church's Spanish ministry grew from a home fellowship into a full Sunday service, reflecting the bilingual character of Chula Vista's 91910 residential core near educational anchors such as Southwestern College. The Third Avenue office coordinates midweek Bible studies, youth programming, and mission-trip logistics for a congregation that spans the South Bay from Chula Vista through National City under a non-denominational governance structure.
