Enroll a Little Sister

Igniting Girls' Passion & Power to Succeed

We enroll girls, trans, gender-nonconforming, and nonbinary youth from age 7 – 14 in our programs. Big Sister Boston accepts referrals from parents and guardians. If you are a service provider and would like to refer a Little Sister, please note the parent/guardian MUST be completing the form with you and will need to be involved in the process. This will ensure that we have consent to process the application and reduce any delays in enrollment. 

If you know a girl, trans, or nonbinary youth who wants to become a Little Sister, call 617.236.8077 or complete the online application form on this page to enroll now. 

To make the best possible match, the enrollment process includes interviews with the Little Sister and her parent or legal guardian. During the interview our team will learn more about the Little Sister’s personality and interests as well as any preferences they may have for the match. 

We conduct interviews and first match meetings virtually. After the initial meeting, visits are expected to occur in person, with the Big Sister picking up and dropping of the Little Sister. 

Big Sister Association of Greater Boston provides mentors to girls, trans, and nonbinary youth in our service area. To refer a boy in this service area, please contact Big Brothers Big Sisters of Eastern Mass or Jewish Big Brothers Big Sisters of Greater Boston. Some Littles have transitioned genders while participating in our program and they are always welcome to continue in our program if they wish.  

Who Can Be A Little Sister?

A Little Sister can be any child between the ages of 7 – 15 who could benefit from the care, support, and attention of a Big Sister. Little Sisters must live in our service area, have the desire to participate in the program, and have approval to participate from their parent or legal guardian.
