The Louis P Singer Fund shows a strong, place-based philanthropic focus on Boulder County and greater Colorado, backing arts and culture, Latino/immigrant services, conservation and nature organizations, and public media and higher education. Grants are predominantly mid-sized awards directed to local nonprofits (many in Boulder), with repeat support for a few core health and community-service organizations. The foundation appears to favor civic and cultural infrastructure — music festivals, orchestras, public radio/PBS, university affiliates — alongside social services that serve low-income and Latino communities and regional environmental groups.
Louis P Singer Fund Inc c/o Market Street Trust Company gives at a scale that supports a small cluster of recurring civic and cultural institutions, with several recent awards at $50,000 or above. In the latest grants, Boulder County Latina League received $60,000 in 2024, while Planned Parenthood of the Rocky Mountains received $55,000 in 2023 and $50,000 in 2024 and 2025. Those awards sit alongside support for music, conservation, public media, and community organizations centered in Boulder and the wider Colorado Front Range. The fund’s pattern suggests a preference for organizations that are already established and serving local public needs, rather than one-off experimental projects. Recent grants also include Boulder Bach Festival, Boulder Philharmonic Orchestra, Colorado MahlerFest, Colorado Public Radio, Rocky Mountain PBS Foundation, Boulder County Audubon Society, Boulder County Nature Association, and The Wild Animal Sanctuary. Across these gifts, the foundation backs both cultural infrastructure and community-serving nonprofits, with repeated funding for some organizations over multiple years. The named grantees point to a portfolio that combines arts presentation, Latino and immigrant-serving work, reproductive health, environmental stewardship, and higher education support.
One clear thread is support for Latino and immigrant community organizations in Boulder County and nearby cities. Recent awards include $60,000 to Boulder County Latina League in 2024, $50,000 to El Comite De Longmont Inc in 2023, $50,000 to Intercambio Uniting Communities in 2023, and $50,000 to El Centro Amistad in 2023. Another major area is performing arts and classical music: Colorado MahlerFest received $55,000 in 2023 and $35,000 in 2025, while Boulder Philharmonic Orchestra, Boulder Bach Festival, Longmont Symphony Orchestra, 3rd Law DanceTheater, Local Theater Company, and Dairy Arts Center also appear in the grant list. The funder also supports conservation and wildlife work, including $50,000 each to Boulder County Audubon Society, Boulder County Nature Association, and The Wild Animal Sanctuary. Public media is another visible line of giving, with $50,000 to Colorado Public Radio and $50,000 to Rocky Mountain PBS Foundation in 2023.

Concentrated, regionally-focused giving in Colorado with many mid-size grants (commonly around $50,000); a mix of repeat support for select organizations and one-off awards to a broader slate of civic, cultural, environmental, and social-service groups.
Notable grantees: Planned Parenthood of the Rocky Mountains, Boulder County Latina League, Boulder Bach Festival / Boulder Philharmonic Orchestra, Boulder County Audubon Society, Colorado Public Radio
Typical grants cluster in the mid-range: the p25 is $1,000, the median is $10,000, and the p75 is $30,000. The recent grant list shows a much larger upper tier as well, with multiple awards at $50,000 to $60,000. The foundation’s 2023–2025 record shows repeat support to several recipients, including Planned Parenthood of the Rocky Mountains, Colorado MahlerFest, Boulder Housing Partners Foundation, and Boulder County Latina League. The organization is a foundation, not an individual-giving vehicle, and it does not make program-related investments. The listed grant purposes are uniform, commonly phrased as support “to further organization’s goals,” which points to broad operating or mission support rather than tightly restricted project grants.
Grantmaking is national in scope, but the recent record is concentrated in Colorado. Boulder appears most often, with additional awards in Denver, Longmont, Lafayette, Centennial, and Keenesburg. The top state by grant count is Colorado, and the grants shown all go to U.S. recipients. There are no non-U.S. recipient countries in the current record. Within Colorado, Boulder-based organizations account for many of the named grants, while Denver and other Front Range cities also appear repeatedly.
The recent record shows support for arts and culture, Latino and immigrant services, conservation and wildlife, public media, reproductive health, and higher education. Named recipients include Colorado MahlerFest, Boulder County Latina League, Boulder County Audubon Society, Colorado Public Radio, Planned Parenthood of the Rocky Mountains, and CU Foundation.
The grant-size distribution is p25 $1,000, median $10,000, and p75 $30,000. The recent grants also include several larger awards at $50,000 to $60,000, showing that the fund sometimes makes substantially above-median gifts.
Yes. Several organizations appear in more than one year, including Planned Parenthood of the Rocky Mountains in 2023, 2024, and 2025; Colorado MahlerFest in 2023 and 2025; Boulder Housing Partners Foundation in 2023, 2024, and 2025; and Boulder County Latina League in 2024 and 2025.
Colorado is the top state by grant count. The recent list includes many Colorado recipients in Boulder, Denver, Longmont, Lafayette, Centennial, Keenesburg, and Boulder County communities.
The listed purposes are consistently phrased as support “to further organization’s goals.” That wording appears across the recent grants and suggests broad mission support rather than narrowly specified project funding.
