Principal's Message


My name is Brittany Corpuz and I serving as your Principal here at Cougar Mountain. This will be my fourth year as the CMMS Principal. Previous to this, I was the Assistant Principal of Cougar Mountain for three years. I taught 1st grade at Graham Elementary, and spent the first nine years of my career as a Teacher, Instructional Coach and Grant Director at a Native Tribal school. I truly love every aspect of being an educator!  It is my goal, each and every day, to create capable, connected and contributing members of our community! I have two children of my own, Kai’leia is 14 and will be in a freshman next year at Graham Kapowsin High School, and Keh’ano is 12 and will be in 6th grade next year here at Cougar Mountain. My husband is Brian Corpuz and he is a 5th grade teacher at Spanaway Elementary. We are truly committed on both a personal and professional level to ensure the success of our students here in Bethel. Cougar Pride!
