Principal Derrick Brown

Many Ideas, Many Voices, One Mission… EXCELLENCE!

Welcome to the 2021-2022 school year at Rockbridge Elementary – A DeKalb County School that is making a difference! I am extremely proud to be the principal of a school that truly believes that teaching and learning are the top priorities of our students, staff and parents.

Rockbridge Elementary School has a wonderful reputation of students, teachers and parents working together to help students move from good to great! I believe it is critical that we all work together to create a caring and collaborative environment that helps our students achieve to the best of their abilities. I hope you will actively participate in the school community through membership in the PTA and volunteering in your child's classroom. The success of your child depends on a strong partnership between the home, the school, and the community.

At Rockbridge Elementary School, we value our relationship with you.
