From Your PTSA President

Welcome to our Interlake Community!


The mission of the Interlake High School PTSA is to encourage a healthy learning environment and sense of community for all students, staff, and families.  

We sponsor community-building events and provide targeted financial grants that enhance student learning at Interlake.  Our goal is to keep the Interlake community informed and up-to-date, as we invite parents to connect with each other and with staff, and as we welcome everyone into conversations about topics that matter to student success. 


What makes Interlake High School such an exceptional place for our students?  

It’s our cultural, social and academic diversity, wrapped in a welcoming and safe environment that encourages learning and provides rich opportunities for our students’ personal and intellectual growth.  


Our students need you. Please get involved!  

Give generously of your time, talents, and treasures.  You’ll find out first-hand what an exceptional place Interlake is.  You’ll meet interesting, friendly people.  And your student will benefit as our entire learning community thrives!
