Meet Principal Erin Connolly

Hello, Eagle families! One of the best parts about being a principal is getting to build relationships with students, staff and families. A few fun facts about me: My family immigrated to the United States in the 1920s from a tiny island off the west coast of Ireland. My favorite young adult book is “A Tree Grows in Brooklyn.” I enjoy listening to folk music, and if I could only eat one type of food for the rest of my life, it would be tacos. My bucket list includes traveling to all of the continents.
