Principal Hallie Mills

Meet Principal Dr. Hallie Mills!

Hello Cascade Ridge Families! After serving as your dean last year, I am very excited to step into the role of principal. I have loved getting to know our Coyote students, staff, and families, and am looking forward to continuing to get to know you all better and to see everyone grow throughout the year! Here are a few fun facts about me: 

  • I grew up on Whidbey Island and graduated from South Whidbey High School. 
  • I have three children ages 8, 13, and 15. You can often find me on the soccer pitch or softball field cheering them on. 
  • I have lived in Washington, Virginia, and Missouri. 
  • I love learning so much that I have gone back to school three times! I have two master’s degrees and my doctorate.  
  • My family and I love to travel within the U.S. and internationally.  
  • Ice cream is my favorite dessert. If I had to choose just one flavor, I would choose mint chocolate chip.
