Nicolette Vandelier

Nicolette VanDelinder | MS History

Teaching students, rather than a content area is my focus. Students learn better when they feel safe, appreciated, and respected in the classroom. The genuine connection between an educator and their students is what pushes them to become their best selves. Whether it’s Social Studies, Game Design, Programming, or eSports, connecting with students is my specialty.
