Meeting the needs of girls

Big Sister Boston is immersed in the diverse communities we serve through a variety of programs. We make and support one-to-one mentoring relationships in the community, in schools, and in workplaces throughout Greater Boston. These relationships are strengthened by the enrichment programs we provide for our Big and Little Sisters which are focused on career awareness, the arts, STEM, safety, wellness, and healthy decision-making. Our programs are designed to support the unique social-emotional needs of girls between the ages of 7-24.

One to One Mentoring Mentoring

Our largest one-to-one mentoring program matches girls between the ages of 7-15 with a Big Sister. These Little Sisters meet individually with their Big Sisters at a date and time of their choosing, and engage in low- to no-cost activities that can range from baking to basketball, watching movies to simply talking with each other. Big and Little Sisters commit to at least one year together and meet twice a month for a few hours.

Little Sisters can remain matched with their Big Sisters until they are 20 years old, at which point they graduate from the program and can become Big Sisters themselves and receive support through the age of 24!

Site-Based Mentoring

Our Site-Based Mentoring programs take place in schools and community centers in Boston, Cambridge, and Quincy. Big and Little Sisters meet once a week during the school day or their after-school program, and commit to at least three academic semesters together, excluding summer break and school holidays. During visits, they read books, learn new skills, work on projects of their mutual choosing, or engage in physical activities. Site-Based Mentoring creates a safe space for girls to have fun, learn, and grow alongside their Big Sisters during their busy school day.

In addition to our traditional Site-Based Mentoring model, we offer these specialized programs:

Big for a Day

Girls who are enrolled with us in Community-Based Mentoring, but not yet matched with a Big Sister can participate in a once monthly group activity with a Big for a Day volunteer led by our staff. This way girls who are waiting to be matched are engaged with us from the start.

Group Mentoring

Our Group Mentoring Program caters to Little Sisters through matches held at schools, community centers, or other youth-centric locations in a group environment. As part of our Group Mentoring Program, girls will be introduced to “Life Choices,” a series of discussion-based activities. These activities offer adolescent girls a safe space to delve into choices, consequences, and alternatives for making healthy decisions. Big Sisters lead small group discussions using a “strengths-based perspective” model, covering various topics such as self-esteem, effective communication, financial literacy, career awareness, conflict resolution, bullying, media literacy, body image, and more. The discussion topics are tailored to the girls’ needs and interests. Our Group Mentoring program provides teen girls in the program the unique opportunity to be both mentor and mentee , fostering a close-knit community and nurturing leadership skills from a young age.

There are two models within the Group Mentoring framework: High School Mentoring and Workplace Mentoring. In the High School Mentoring Program, teenage Big Sisters act as mentors to younger girls. They also engage in leadership training led by the Big Sister Boston staff. Workplace Mentoring offers girls the chance to explore career awareness. Little Sisters are paired with employees from a partner company of Big Sister Boston, meeting their Big Sister at the company’s office. This setup not only provides a valuable mentoring experience but also encourages the girls to think big about their futures.

Engagement and Enrichment Programs

We are more than mentoring. Our enrichment programs foster sisterhood among our Community-Based Mentoring matches while promoting girls’ physical, social, and emotional health. Activities are designed to build skills and broaden Little Sisters’ horizons at different ages and stages of development as they learn and grow alongside their Big Sisters. Our staff host these activities in partnership with talented individuals, local businesses, and community and civic organizations.
