Mission & Vision

Our mission is to ignite girls’ passion and power to succeed through positive mentoring relationships with women and enrichment programs that support girls’ healthy development. Ultimately, our vision is to create a mentor-rich community in which every girl has access to the individual nurturing, guidance, and support she needs to become a confident, competent and caring adult. We are a national model for gender-intentional mentoring for girls which can be replicated in other mentoring programs.

Nationally Recognized

Big Sister Boston is proud to be recognized by Big Brothers Big Sisters of America as the 2015 national Agency of the Year for our substantial growth in the number of children served, quality and length of mentoring relationships, and increased revenues that support our agency financially. We believe that all children can benefit from the care and guidance of an adult mentor and, that when girls’ unique needs are addressed, they thrive with increased confidence, improved relationships and the ability to achieve their individual goals. We are part of a network of more than 300 Big Brothers Big Sisters of America agencies. We are the only affiliate solely serving girls.

History

Big Sister Association of Greater Boston was founded in 1951 by the Reverend Harold Taylor, Assistant Rector at Christ Church in Cambridge; Edith Taylor, a Cambridge police officer; and Frances Marley, an administrative assistant and legal consultant for the Society for Prevention of Cruelty to Children. Believing that girls in the community could benefit from the guidance and support of an older female friend, they created a one-to-one mentoring program where girls (Little Sisters) were individually matched with caring and committed volunteers (Big Sisters). In our first year, we matched six girls.

Service Area

75% of the girls we serve live in the neighborhoods of Boston, and our service area extends to 69 cities and towns throughout Greater Boston, including north to Boxford, south to Foxboro, and west to Wayland.
