Interested in being a Site-Based Mentor?

Thank you for your interest in being a Site-Based Big Sister!

Site-Based Mentoring takes place in schools in Downtown Boston and Cambridge. As a Big Sister, you would meet once a week with your Little Sister during her lunch time or after school program to build a friendship with her through arts and crafts, playing at recess, or playing games. You would be matched with a girl between the ages of 7-10. Big Sister Boston makes intentional matches based on background, interests, and personality, and they will be with you during every step of your match relationship!

Please fill out this form to let us know what would work best for your schedule.
