Principal's Message

Welcome to Granite Hills High School, home of the “GRIZZLIES”.

I am honored to be the Principal of Granite Hills High School. It is with great anticipation that we look forward to working with parents and community, in partnership to help students prepare for college, career and life. With your assistance, we will teach students to understand their educational potential, while emphasizing their responsibility to the Porterville community.


As Granite grows, the goal remains to provide a “family like” atmosphere, while providing a solid educational foundation that will enable them to contribute with integrity and confidence. We take pride in our strong instructional programs, pathways, and excellent extracurricular programs. We believe that ALL students can learn and be successful!
