Annual Report FY17: Big Brothers Big Sisters of Massachusetts Bay


The mission of Big Brothers Big Sisters of Massachusetts Bay is to partner with under-resourced families to provide their children with transformational, one-to-one professionally-supported relationships with caring adult mentors, so that their children will thrive.

  • We are the largest one-to-one youth mentoring organization in New England. Founded in 1949 in Boston, this year we will serve over 3,000 children throughout Eastern Massachusetts.
  • We are a leader within the Big Brothers Big Sisters national network, and a proud affiliate of one of the most recognized and prestigious non-profit brands in America. We are at the forefront of new technologies and youth outcomes work that have broad implications for both the mentoring field and positive youth development.
  • We are proud partners with hundreds of corporations, educational institutions and municipal agencies –  working together to serve children and achieve organizational missions.

Our program matches adult volunteers with children who need adult mentors and friends. With adult attention and guidance supporting their positive development, their lives change for the better and ultimately impact the community. We are serious about our data and encourage you to study the evidence of our impact. We also hope you’ll spend some time getting to know some of our Bigs and Littles in the program. Their stories will inspire you.
