Meet Principal Erin McKee!

Hi, Falcon families! My favorite part of being a principal is greeting our students each morning. A few fun facts about me: If I could only eat one cuisine for the rest of my life, it would be Japanese food. My bucket list includes attending a Beyoncé concert. I’m really good at parallel parking.
