Mission Hills provides top-quality education to students. We have two campuses: Union City (grades TK-8) and Castro Valley (grades TK-5). Both locations have year-long open enrollment, based on a first-come, first-served basis. The goal of MHMS is to raise confident, intellectual, and well-rounded children for a better tomorrow.
Mission Hills prides itself in offering small class sizes (15-24 students) with an enhanced learning environment for the students. Both schools provide an emphasis on learning and academics with a balance of creativity and innovation. Students and families become a part of our Mission Hills community, filled with fun spirit days, opportunities to volunteer at different school events, and so much more!
Mission Hills School is the place where minds are thinking while faces are smiling.
Please call to schedule a tour or for additional information about our school and how we may assist you and your child.
