The agency matches a child (a Little) with a vetted volunteer adult mentor (a Big) in a one-to-one relationship supported by professional staff. The relationship gives a child a consistent, caring adult presence, which research links to higher confidence, stronger school engagement, and resilience.
Based in the Portland area, the agency focuses its resources on the two southern Maine counties where most of the state's population lives, building matches that meet regularly for activities and conversation.
Big Brothers Big Sisters of Southern Maine serves Cumberland and York counties, which include Portland, the state's largest city, and the surrounding communities. Together these counties hold a large share of Maine's population.
Concentrating on this region lets a relatively small agency provide close, consistent match support, the staff time that keeps mentoring relationships safe and effective.
Founded in 1995, the agency has matched southern Maine children with adult mentors for about three decades. Nicole Avery serves as executive director, and annual revenue is about $2.5 million.
Like many smaller nonprofits, the agency has navigated changes in its physical footprint; in late 2025 it sold its Westbrook office and was working remotely while exploring a new space, with its mailing address in Westbrook.
To become a Big, visit somebigs.org or call 207-773-5437. Volunteers complete an application and screening process, then are matched with a Little and supported by agency staff throughout the relationship.
The agency continually recruits adult mentors across Cumberland and York counties, since demand from families typically exceeds the number of screened volunteers available.
Donations can be made at somebigs.org. The agency is a 501(c)(3) organization, so gifts are tax-deductible. Corporate partnerships, foundation grants, and individual giving make up the agency's roughly $2.5 million in annual revenue.
Gifts that fund match support help the agency keep relationships safe and effective over the long term.
The Portland area has youth-serving organizations including Boys and Girls Clubs and community programs. For one-to-one, professionally supported mentoring in Cumberland and York counties, Big Brothers Big Sisters of Southern Maine is the dedicated agency, with about three decades of history.
