First Baptist Church of South San Francisco is a small Baptist church that also operates Roger Williams Academy, a K-12 Christian school. The congregation of 20 meets in the school chapel on Sundays; an extension service also meets Sunday afternoons in Concord at the home of one of its members. First Baptist rents out its attached church space to six other congregations, including Brazilian, Spanish, Korean and Filipino churches. All children in the congregation go to Roger Williams Academy, which now enrolls 20 children across the grades, where they receive a comprehensive Bible education. Roger Williams also rents space to an independent preschool.
