Key takeaways

If your organisation is a Washington, D.C.-based non-profit working in paediatric care, cancer care or cancer research, the Trust's stated focus fits your work.
Its paediatric support centres on children in the District's most disadvantaged and vulnerable neighbourhoods, so projects that reach those families will be a closer match.
The Trust does not fund endowments, building programmes, capital campaigns or scholarships for individuals, so do not ask for those.
A first-time applicant should submit a letter of inquiry online and wait for the trustees to say whether a formal proposal would be appropriate, and the trustees may ask follow-up questions or make a site visit.
Grant applications have a normal annual deadline, but no grant range is stated, so base your request on the costs of your project rather than on an assumed size.
