    Strawberry Breakfast

    Strawberry Breakfast is a long-standing Allendale Columbia tradition and features a short program honoring the seniors with dances, songs, and special ceremonies. This is followed by refreshments (including strawberries!) in the Dining Commons. All family members are invited to attend this event and many students are involved in the program. This year’s Strawberry Breakfast will take place in the AC courtyard from 8:30 - 10:00 a.m. on Friday, May 23rd. There are no classes on this day, so there will be no buses, attendance, or classes and students should leave campus after the event.
