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.
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 250 Big Brothers Big Sisters of America agencies. We are the only affiliate solely serving girls.
We believe we can only do our work effectively if we value:
Community: A diverse constituency of stakeholders with joint ownership and collaborative participation in the vision and mission
Courageous Communication: Taking a risk, challenging norms, asking questions, owning our intent and our impact, listening, and seeking and accepting feedback in order to improve outcomes
Cultural Responsiveness: Genuinely embracing, working with, and continually learning about cultural differences
Empowerment, Learning: Through curiosity, humility, and rigor, we increase autonomy and self-determination in order to represent one’s interests in a responsible way
Equity: Striving for a fair, just, and healthy society where girls of diverse racial, social, and economic backgrounds have equal access to opportunities
Sisterhood: Building across individual and collective differences to foster relationships that honor past and future generations of women and girls who are committed to each other’s success
Stewardship: Fostering a lasting, caring connection between our community and the resources we need to achieve our mission
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.
