School Overview

Hillsdale High sits in the heart of San Mateo, a Bay Area city that strikes a comfortable balance between suburban calm and easy access to San Francisco and Silicon Valley — making it a natural fit for families who want proximity to opportunity without the frantic pace of the tech corridor.
