Since 1951, Big Sister Association of Greater Boston has been helping girls reach their full potential through positive mentoring relationships with women. Big Sister is the largest mentoring organization in Greater Boston exclusively serving girls, covering 69 cities, towns and communities. We could not serve the girls that we do without the dedication of our staff, Board of Directors and the thousands of volunteer mentors who give time and friendship to their Little Sisters.
Big Sister Association of Greater Boston's mission is to help girls realize their full potential by providing them with positive mentoring relationships with women.
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. Using research-based best practices, we hope to become a national model for gender-specific mentoring for girls which can be replicated in other mentoring programs.
Big Sister is an acknowledged leader in building professionally supported, dynamic relationships between girls and adult women volunteers.
