Ways to Give
We are 100% invested in girls.
We offer a variety of ways to show your investment in girls through charitable giving.
We 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-sensitive mentoring for girls which can be replicated in other mentoring programs.
Making an Impact with
Our Programs
Big Sister Boston is immersed in the diverse communities we serve through a variety of programs. We make and support one-to-one mentoring relationships in the community, in schools, and in workplaces throughout Greater Boston. These relationships are strengthened by the enrichment programs we provide for our Big and Little Sisters which are focused on career awareness, the arts, STEM, safety, wellness, and healthy decision-making. Our programs are designed to support the unique social-emotional needs of girls between the ages of 7-24.
Thriving with
Our Partners
Big Sister Boston is able to offer the depth of programs and activities that we do thanks to our partnerships throughout Greater Boston. From major funders, to academic institutions, to community organizations, we are proud to be supported by a community of partners who are invested in girls.
