Key takeaways

  • This Winchester, Massachusetts foundation funds a wide range of causes, including medical research, Catholic elementary education, reproductive health care, mentoring, camps and other programmes for children and young people, substance-use education and treatment, scholarships, orchestral education, community programmes, church support and social services, so check your work fits one of these areas before approaching.
  • No geographic focus is stated, though its recorded giving is heavily concentrated in Massachusetts.
  • A realistic request would be modest: about 8 in 10 of its 153 grants fall between $5,000 and $150,000, with a median grant of $25,000, though its largest grant reached $2,250,000.
  • The foundation says it makes contributions only to preselected charitable organisations and does not accept unsolicited requests, so a grant writer cannot simply submit a cold proposal and should look for some other route to an invitation.
  • Giving looks relationship-led rather than open-competition: 79% of its grant dollars to organisations went to organisations it had also funded in its two prior filings, so new approaches should be made with that pattern in mind.
