Meet Principal Andrew Brownson

Welcome, Patriots and families! The piece I love most about being a principal is seeing our students helping one another, achieving a goal, or working to make their world a better place. I find inspiration in that, and am reminded of the importance of school and the opportunity that I have to make a difference. A few fun facts about me: My favorite children’s book is “If You Give a Mouse a Cookie.” If I had to pick my favorite type of music, I would choose country. My bucket list includes writing something and having it published. And, I like cooking; my favorite dish to make is smoked brisket.
