Our new principal, Sheila McCumber, joined Sun Terrace at the end of October 2025.
Sheila earned her B.A. in French from Central Michigan University and her M.A. in Educational Administration from California State University Northridge. She has worked as a District Teacher Leader, a vice principal at Ygnacio Valley HS in 2021-2022, and as an assistant principal in a nearby school district. Outside of work, Sheila enjoys hiking, running, and spending time with her family and pets.
Our new mural painted on the MU building during the summer of 2025! It’s a vibrant addition to our campus and a celebration of our school spirit.
