Performing Arts Festival — Friday, May 1 at 3:30 p.m.
The Performing Arts Festival takes place on stage in Founders Hall, offering a relaxed and informal alternative to main stage productions. Beginning after school and running through the afternoon with short breaks between acts, the festival is open to the public, and the entire MBS community is warmly invited to attend.
Unlike traditional performances, students sign up rather than audition, creating a low-pressure space to showcase their talents. Past acts have included monologues, musical performances (both covers and originals), poetry readings, magic, gymnastics, and even stand-up comedy. Both Middle and Upper School students are encouraged to participate—no audition required!
Please contact Mr. Marmo if you are interested.
Grandparents & Special Friends Day — Friday, May 15
Grandparents and special friends of our Middle School and Upper School students are invited to join us on Friday, May 15, 2026! The day's program includes an assembly with student performances, refreshments in the Lee Kellogg Sadrian Dining Hall, and campus tours. Arrival is at 12:15 p.m. in the Founders Hall Lobby.
Please register using the Grandparent's or Special Friend's name and contact information (not the parent's). This will help ensure we have proper names for name tags, and that they receive any important updates, such as notifications about weather or parking, or event follow-ups.
