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.

*Corporate Partner of the Year, 2013


Blue Cross Blue Shield of Massachusetts has been an outstanding corporate partner and significant investor in Big Sister for more than a decade. Over the years, this relationship has strengthened not only with an increase in financial support, but with an expansion of employees who volunteer to become Big Sisters, including Blue Cross Blue Shield of Massachusetts employee and Big Sister, Elly Van Faasen.  Blue Cross Blue Shield of Massachusetts actively encourages employees to become Big Sisters, hosts recruitment events for Big Sister, and offers opportunities for professional development to Big Sisters by inviting them to networking events. Each contribution of $1,000 represents one Little Sister we can serve; and throughout our partnership, Blue Cross Blue Shield of Massachusetts has sponsored nearly 500 Little Sisters.
