What Big Brothers Big Sisters of Eastern Massachusetts does
Big Brothers Big Sisters of Eastern Massachusetts (BBBSEM) is a 501(c)(3) nonprofit youth mentoring organization founded in 1949 and headquartered at 184 High Street, Boston. It operates as the largest Big Brothers Big Sisters affiliate in New England and the second-largest in the United States, delivering professionally supported one-to-one mentoring relationships ("Bigs" matched with "Littles," typically youth aged 7–18) across six regions of Eastern Massachusetts: Brockton, Cape Cod & Islands, Greater Boston, Lowell, Merrimack Valley, and South Coast. The organization served nearly 3,000 youth annually historically and has set a target of more than 4,000 youth per year, with cumulative service exceeding 25,000 youth over its 75-year history.
BBBSEM delivers its services through a portfolio of program modalities: traditional community-based mentoring (2–4 hours twice monthly), site-based programs at schools and workplaces, school and campus-based programs (including partnerships with 12+ colleges), the Big Futures hybrid four-year high-school-to-post-secondary pathway program launched in 2023, and Girls' Gender-Intentional Programming. Its technology footprint is minimal and operationally oriented — the proprietary "Big Portal" provides resource, activity, and match-support content for mentors and families, but the organization is not technology-led. The merger with Big Sisters Association of Greater Boston, completed in February 2025, expanded gender-intentional programming capabilities.
The business model is donation- and event-driven. There are no fees charged to families or volunteers. Revenue is generated through individual donations, corporate partnerships (e.g., C-Space, TripAdvisor, Mother.ly, Ergobaby via the SitterStream 100 initiative), and a calendar of fundraising events including Big Night (annual gala, raised $1.5M+ in 2023), Big Golf Tournament (raised $600K+ cumulatively since 2003), the Boston Marathon team, and the Falmouth Road Race. Customer "segments" are non-paying end beneficiaries (youth and families) and contributing supporters (volunteer mentors, donors, corporate sponsors), accessed through direct volunteer enrollment, family enrollment, school and employer partnerships, and community outreach across the six operating regions.
