Principal's Message


Mr. Perdomo

Greetings Gladstone Middle School Community,

On behalf of the faculty and staff at Gladstone Middle School (GMS), it is my pleasure to welcome you to the 2023-2024 school year.  As the first principal of GMS, 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 GMS, 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 and prepare them for high school. 

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.  We are excited to utilize our new college and career-ready lab and we are ready to compete in the San Gabriel Valley Middle School Sports League. 

We hope that you and your student will take advantage of the many available opportunities to enhance their educational experience at GMS.


Sam Perdomo

Principal - Gladstone Middle School
