Intervention Administrator, MMS

Mrs. Dawn McCullough, Assistant Principal

Hello! I am Ms. McCullough, the Assistant Principal at MMS. 

I began teaching Science in 1999 for Long Beach USD. One year later, I made the move to Temecula and Margarita Middle School. It was my honor and privilege to have taught Science to so many amazing Mustang students before leaving the classroom in 2023 to take on my new role as Assistant Principal. Margarita has been my home for nearly 25 years and I am dedicated to the success of our students and community. I love being a Mustang! 

My husband is also in education as a teacher at Chaparral High School. We have two incredible boys, Jaren and Sean. Our family enjoys water sports on the lake and riding quads, motorcycles and Razors in the Glamis sand dunes. 

MMS is blessed with an incredible community that I am fortunate to be part of. I look forward to partnering with all of you to create another fantastic and successful year at MMS.

Every day is a great day to be Mustang STRONG!
