Based in Boston, Mass Mentoring Partnership (MMP) is fueling the movement to expand empowering youth-adult relationships  across Massachusetts. MMP serves more than 250 mentoring and youth development programs statewide supporting more than 33,000 youth in mentoring relationships. We assess programmatic needs and organizational capacity, as well as provide customized strategies that empower youth, families and communities.

Our program network includes schools, religious organizations, community non-profits, and workplaces serving youth 5 to 18-years-old. These institutions utilize a variety of program structures including one-to-one mentoring, group mentoring and e-mentoring.

History and Accomplishments

Mass Mentoring Partnership was founded in 1992 by the then-president of Boston College, J. Donald Monan, S.J., and the CEO of New England Telephone, Paul O'Brien, as Greater Boston One-to-One, the first local extension of the national organization One-to-One. Since then, MMP has had a rich history of catalytic involvement in the start-up and sustainability of high-quality mentoring programs.

  • Expanding our mission to include providing services and support to youth serving organizations in addition to mentoring programs, growing our number of youth impacted to more than 250,000.
