Big for a Day

By Big Sister Association of Greater Boston

Volunteer as a temporary Big Sister for a day! Opt-in to participate in our monthly activities as they fit your schedule and interests.

This is an ongoing program.
Sunday and Saturday.

As soon as a Little Sister is enrolled with us, she is eligible to participate in Big for a Day while she is waiting to be matched with a Big Sister. Every month, our staff hosts weekend activities for these Little Sisters who are then matched with a temporary Big Sister for that day. The fun, skill-building activities include book clubs, fashion design sketching classes, yoga, scavenger hunts, coding workshops, and more! This program is currently virtual. 

Ages: Adults.


Big Sisters must be at least 20 years old, but there is no age maximum.
