We Are Collaborative

Big Sister offers the depth of programs and activities that we do thanks to our collaborations throughout Greater Boston.  Big Sister partners with local corporations that allow employees to volunteer during the workday, colleges that encourage their students to give back, and area nonprofit organizations that connect women, girls, and families to critical resources. These valuable partnerships help us serve more than 2,600 girls annually with quality mentoring.



Big Sister is fortunate to partner with caring and committed community-based organizations and institutions that make a difference in children’s lives.
