The Margaret Ann Enderlein Charitable Trust appears to make large, place-based gifts to philanthropic intermediaries rather than to direct-service programs. Its sole reported grant is a substantial, unrestricted gift to the Waterloo Community Foundation, indicating a preference for strengthening local community endowments that can support a range of needs over time.
Highly concentrated: a single large unrestricted grant to a community foundation, suggesting one-time or infrequent major gifts to philanthropic intermediaries rather than many small grants to direct-service nonprofits.
A single 2025 gift of $338,468 to Waterloo Community Foundation stands out in the Margaret Ann Enderlein Charitable Trust’s recent record. That grant points to a pattern of channeling substantial support through community institutions rather than through individual programs alone. The trust also made repeated educational gifts to Allen College of Nursing Foundation, with grants of $37,671 in 2025, $36,958 in 2023, and $32,156 in 2024. Those recurring awards show an interest in steady support for a local educational institution over multiple years. The trust’s recent grants also reach arts and cultural organizations in the Waterloo area, including Waterloo Center for the Arts and Waterloo Cedar Falls Symphony. In that mix, the foundation appears to favor place-based giving centered on a small set of Iowa recipients, with a strong emphasis on intermediary philanthropy, education, and local cultural infrastructure. The pattern is compact, recurring, and closely tied to named institutions rather than a wide array of one-time grantees.
Education is one of the trust’s clearest areas of support. It gave $37,671 to Allen College of Nursing Foundation in 2025 for educational purposes, following grants of $36,958 in 2023 and $32,156 in 2024 to the same organization. That repeated support suggests an ongoing relationship with the college foundation. The trust also funds community philanthropy. In 2025, it awarded $338,468 to Waterloo Community Foundation, a large gift that fits its intermediary-based approach. Arts and music appear as secondary themes. In 2025, Waterloo Center for the Arts received $18,836, and Waterloo Cedar Falls Symphony received $18,835. Earlier grants to both organizations in 2023 and 2024 show that cultural institutions are part of the trust’s giving pattern, alongside education and community endowment support.
Typical grant size sits in a fairly tight range: the 25th percentile is $17,879, the median is $18,657, and the 75th percentile is $33,356. The distribution is shaped by one much larger 2025 grant to a community foundation, while the rest cluster around the high teens and low 30s. Grants recur across multiple years, especially to the same Iowa recipients, indicating an ongoing rather than one-time pattern. The trust is a charitable trust, not a funder of individuals, and it does not make program-related investments.
