Peter and Ann Lambertus Family Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- This foundation operates by invitation only and does not accept unsolicited requests, so a cold approach is unlikely to be the way in; being known to the foundation or its trustees looks more promising, especially as 99% of its grant dollars in its latest filing went to organisations it had also funded in the two filings before that.
- A realistic request size is modest: half of its 206 grants across its last three filings were $15,000 or less, and about 8 in 10 of grants fall between $4,000 and $100,000, though the largest single grant recorded was $10,000,000.
- Grants are recorded as general support rather than for specific projects, and recipients span animal-welfare and rescue organisations, hospitals and medical institutions, educational institutions, conservation organisations, arts and cultural bodies, libraries and historical societies, policy institutes and social-service organisations, so a wide range of charitable fields appears in its giving.
- No geographic focus is stated, though the filings show grants mainly in Massachusetts and Indiana.
- Given the invitation-only process and the high share of grant dollars going to previously funded organisations, this reads as a relationship-led foundation rather than a competitive open programme, though its portfolio includes both large institutions and smaller local groups.
Overview
Peter and Ann Lambertus Family Foundation is a US private foundation based in Norwood, MA.
What they fund
Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.
Priority Areas
The filing records the grants as general support, rather than identifying specific project purposes. Recipients include animal-welfare and rescue organisations, hospitals and medical institutions, educational institutions, conservation organisations, arts and cultural bodies, libraries and historical societies, policy institutes and social-service organisations. The record therefore describes a varied portfolio of charitable organisations working across several fields, rather than a programme defined by one stated subject area. It shows both large institutions and smaller local groups among recipients, with repeat support going to organisations funded in an earlier filing.
Geographic Focus
No geographic focus is stated; the filings show grants mainly in Massachusetts and Indiana.
