Areumdaun Church in Chula Vista is a Korean-language Christian and Missionary Alliance congregation whose name translates to "beautiful" in Korean, worshipping on the Hilltop Drive campus since the organization's IRS recognition in 1972. The congregation shares the 580 Hilltop Drive facility with St. Mark's Lutheran Church, forming a multilingual campus that hosts separate English, Spanish, Mandarin, and Korean worship services under one roof. Korean-language prayer meetings convene six mornings per week in the main worship center, making Areumdaun one of the few daily-prayer congregations in the South Bay region. Community-service ministries and children's programming operate within a Hilltop Drive corridor that also includes Hilltop Drive Elementary School, anchoring the church in a neighborhood with high foot traffic from families in the surrounding 91910 residential blocks. The shared-campus model distributes facility costs across four language-specific congregations, each maintaining independent pastoral leadership while coordinating building usage through a unified scheduling system.
