Upper School Clubs & Activities
Hero Treatment
Clubs and Activities develop leadership and social awareness.
Beyond class, MBS students take part in many clubs and activities, and their involvement fuels a powerful School spirit.
Co-curricular opportunities include everything from a Student Government Association with a real voice in school life to Crimson Sun, our school newspaper, Kaleidoscope, our multi-cultural diversity club, the Film Club, the Community Service Club, a Dungeons and Dragons Club, and much, much more. Students also turn out in enthusiastic numbers for Coffee House and mini-concerts in Wilkie Hall and our Contemporary Music Workshops—two annual blockbuster performance events spotlighting MBS talent. Like so many school activities, these events are organized and run by students, reflecting their energy and ideas.
