School Overview

Grossmont High sits in the heart of La Mesa, a laid-back inland suburb just east of San Diego with a small-town feel and easy access to the city. The school lands solidly in the middle of the pack statewide, with science as a particular strength, making it a decent fit for students with an interest in that direction. Families who want a suburban San Diego lifestyle without the coastal price tag — and who value a school with real community roots in its neighborhood — tend to find Grossmont a comfortable fit.
