Principal's Message

  • Greetings Gladstone High School Families and Community

    On behalf of the faculty and staff at Gladstone High School (GHS), it is my pleasure to welcome you to the 2022-2023 school year.  As the principal, I am honored to be a part of a faculty and staff that is committed to working together to provide the best education we can for our students.  At Gladstone High School, we are committed to ensuring that we meet the needs of the whole student to ensure academic success. Our goal is to support all students so that they can graduate and pursue their goals after graduation.


    This school year we will continue to emphasize creating positive relationships, an academically rigorous learning environment that promotes college and career goals through a standards-driven curriculum, and student-centered interaction, as well as strong extracurricular programs.  Our work is highlighted by our Medical Pathways, Career Technical Education, Early College Program (ECP) and Advanced Placement programs. My goal as the principal of GHS is to guide and support our staff and students to reach their highest potential in a safe and nurturing environment. 


    We hope that you and your child will take advantage of the many available opportunities to enhance the educational experience here at GHS. Please contact our office at 626-815-3604 or email me directly at, if you have any questions or concerns.
