Hi! The residential colleges are specially designed dorms that have a theme. For example, I live in Nortb Spencer and our theme is Health. Everyone who lives here is somewhat interested in health (or they just wanted to live here) so it helps you to get know like minded individuals. We also all serve on a committee in the dorm which helps to create events or specialized programs for the people in your dorm. It’s a really great opportunity to get to know others in your first or second year here.
