"Where every child is brilliant!"


"Our mission is to provide every student enrolled at Mission School access to a challenging and comprehensive curriculum presented by a passionate and dynamic staff in a learning environment that emphasizes enthusiasm, responsibility, and respect.

message from the superintendent/principal Mrs. Sandra Shreve

I am so honored to serve our Mission School Community! A little about me - I've been in education for more than 20 years, serving as a 4th, 5th, 6th, 8th, and 9th-12th grade teacher, as well as a site administrator for the past 6 years, all within Southern and Central California.  I received my B.A. from UCLA, my Administrative Credential from USC, and my Master's in Educational Leadership from GCU. 

My Educational Philosophy: "I believe every child is brilliant! It's our shared responsibility as educators and parents to work together with our children to help them see their brilliance, and provide the resources, guidance, support, and care they need each and every day to reach their highest potential. 

Every student...every day...whatever it takes!"
