What a joy to welcome alumni back to campus for Reunion 2026! We kicked things off by celebrating legacies: those of both the French Gym, now transformed as the East Quad, and our beloved retiring faculty, Michael Weinstein and Nailah Randall-Belinger.
The weekend continued with a full day of reconnection and communion — from class workshops and campus conversations to class parties filled with laughter, memories, and renewed friendships. Thank you to everyone who came back to celebrate together — representing generations of alumni from the 1950s to today.
