Distinctly South Bay Christian School 

At South Bay Christian School, we strive to create an exceptional learning environment that sets us apart from other schools. We pride ourselves on providing a safe, friendly, and nurturing atmosphere that makes learning enjoyable for all of our students.

One of the ways we achieve this is by maintaining small class sizes, with a maximum of 25 students per grade. Our curriculum extends beyond standard subjects to include STEM, music, art, bible, and physical education, delivering academic rigor while fostering character development with a zero-tolerance policy for bullying.

Our school campus features a private, expansive outdoor play area, complete with swings, a play structure, sport court, treehouse, and soccer fields. In addition, each grade participates in field trips and community service projects to expand their learning beyond the classroom.

We offer affordable before and after school care programs, as well as after-school enrichment programs that provide exciting extracurricular activities. Middle school students can even sign up for competitive sports such as volleyball, basketball, soccer, and ping pong.

Finally, we believe in the importance of building a community, and we regularly host school events that welcome family and friends. Overall, South Bay Christian School is a place where students love coming to learn, grow, and thrive.
