Colburn Foundation

The Colburn Foundation operates as one of the most tightly focused classical music funders in the United States — a private foundation with $204M in assets whose entire grantmaking universe centers on the performance, education, and training of classical musicians, almost exclusively in Los Angeles. Founded in 1999 by Richard D. Colburn, a businessman and lifelong viola player who served as a director of the Los Angeles Philharmonic, the foundation reflects its founder's personal passion with unusual fidelity: no jazz, no world music, no contemporary composition, no commissions.

The critical first fact for any prospective applicant: the foundation strongly discourages unsolicited applications. Its process is explicitly relationship-driven. The foundation invites returning applicants — which constitutes the large majority of its grantee pool — and admits only a very limited number of new organizations each cycle. Breaking into this portfolio requires patience, persistence, and a genuine prior relationship.

For organizations that are not yet known to Colburn, the path forward is a phone call to (818) 399-4427 or an email to Grants Administrator Carol Rinn at crinn@colburnfoundation.org. This is not a courtesy step — it is a formal prerequisite. From that initial conversation, the foundation may invite a Letter of Intent. If your organization is entirely unfamiliar to them, expect a site visit or program observation before any further steps are encouraged.

First-time applicants should understand the relationship arc: the foundation's top 50 grantees each show three consecutive grant cycles in the data, reflecting a portfolio of long-term partners rather than one-time awards. The Colburn School has received $12.1M across three tracked grant periods; the Los Angeles Opera $2.8M; the Los Angeles Philharmonic $2.8M. These are not transactional relationships — they are sustained institutional partnerships. Newcomers should enter with a multi-year engagement mindset, not an expectation of immediate funding.

The Colburn Foundation's giving has grown substantially over the past decade, driven by strong investment returns on a $204M endowment. Total giving in fiscal year 2023 reached $14.9M (grants paid: $12.9M), up from $11.7M in 2022, $6.7M in 2021, and $6.8M in 2019. The 2024 fiscal year shows $19.4M in total revenue but grants paid are not yet reported — suggesting another strong year is likely.

The most striking feature of this foundation's grant distribution is its extreme concentration at the top. The Colburn School receives $12.1M across three tracked grant cycles — roughly 44% of all recorded giving in the dataset. Strip that out, and the remaining portfolio divides $15.1M across 270 grants to approximately 85 organizations, averaging about $56,000 per grant per cycle.

For organizations outside the Colburn School, the grant landscape looks like this: - Large institutional grants ($500K–$2.8M): Los Angeles Opera ($2.8M total), Los Angeles Philharmonic ($2.8M), Los Angeles Master Chorale ($1.3M), Los Angeles Chamber Orchestra ($1.1M), Musica Angelica ($1.0M), USC Thornton School of Music ($553K) - Mid-tier grants ($100K–$500K): KUSC Radio ($300K), Da Camera Society ($266K), California Institute of the Arts ($245K), Idyllwild Arts ($241K), UCLA Foundation ($215K) - Smaller operating grants ($40K–$100K): Most of the portfolio falls here — youth orchestras, community music schools, chamber ensembles, and choral organizations receiving $40,000–$90,000 per three-year cycle (~$13K–$30K annually)

The database reports a median grant of $12,500 and average of $96,606, with a range from $1,000 to $4,085,489. The low median reflects a long tail of small annual grants to community-level organizations. Most operational grantees outside the Colburn School anchor in the $15,000–$50,000 annual range. Geographic concentration is acute: 250 of 273 recorded grants went to California organizations, with the balance split among DC, Michigan, New Mexico, New York, and Pennsylvania.

The Colburn Foundation sits in a distinctive niche: a large-asset private foundation ($204M) with one of the narrowest program mandates of any similarly-sized funder in the country. Its peers by asset size are generally broader in focus.

Colburn is notably more generous as a percentage of assets than many comparable foundations: its 2023 giving of $14.9M represents approximately 7.3% of its $204M asset base, well above the 5% minimum payout requirement. This signals a board willing to spend down aggressively in service of its mission rather than preserving capital.

Among Los Angeles classical music funders, Colburn occupies the top tier alongside the Ahmanson Foundation and major institutional endowments. No other private foundation in Southern California matches its singular, deep commitment to classical music as the sole programmatic focus. For organizations working at the intersection of classical music and education, Colburn should be considered a tier-one priority funder in the regional landscape.

The most recent publicly available financials (fiscal year 2023) show the Colburn Foundation at an inflection point: $14.9M in total giving, assets up to $194M from $182M the prior year, and net investment income of $13.3M. The 2024 preliminary data shows assets at $204.4M and $19.4M in revenue — suggesting continued endowment growth and likely another robust year of grantmaking when the full 990 is published.

The foundation's published 2026 grant calendar indicates four application windows remain active: the winter window closed January 12, 2026; the spring window runs approximately March–April 2026; the summer window approximately June–July 2026; and the fall cycle opens September 25 with a board meeting anchor date of September 8, 2026. This quarterly cadence has been consistent for several years.

No major leadership transitions have been reported. Executive Director Allison Sampson has been in the role across at least three consecutive years in the financial data (compensation growing from $75,000 to $88,350), suggesting stable program leadership. Carol Rinn serves as Grants Administrator and is the named point of contact for all new applicant inquiries. Board leadership includes Chairman Carol C. Grigor and directors including members of the founding Colburn family (Richard Colburn, David D. Colburn).

The foundation's profile was last updated by grantmaker databases in January 2026, with no announced strategic pivots or program restructuring. The classical music-only mandate and invited-application model appear stable.

First contact is non-negotiable. The foundation explicitly states: do not submit a Letter of Intent or application without contacting them first. Call (818) 399-4427 or email Carol Rinn at crinn@colburnfoundation.org. This is described as a requirement, not a suggestion. In that conversation, be prepared to articulate your organization's focus on classical music performance or education in Southern California in two or three concise sentences.

Align with the classical tradition strictly. The foundation funds organizations primarily performing or educating in the Western classical tradition — broadly the 17th through early 20th century repertoire. Jazz, world music, contemporary composition, and genre-crossing programs are explicitly excluded. If your programming is predominantly classical with minor contemporary elements, lead with the classical core. Do not mention jazz or world music unless asked.

Request general operating support. The overwhelming majority of Colburn grants are unrestricted general operating support. Frame your ask as operating support for your classical music mission rather than a project grant. This aligns with how the foundation thinks about its partnerships — as sustained institutional support, not transactional project funding.

Have audited financials ready. The application requires two years of audited financial statements (or Form 990s if not audited), plus a current-year budget for future-year funding requests. Organizations without audit capacity should prepare internal financial statements for the most recently completed fiscal year.

Expect a site visit if you're new. The foundation's instructions state that for unfamiliar organizations, they will want to meet and/or observe your program before encouraging formal application. Invite the foundation to a concert, masterclass, or educational event early in the relationship-building process — long before any application is submitted.

Apply during a quarterly window. There are four application periods per year, each anchored to a board meeting. Missing a window means waiting 12–16 weeks for the next. For fall 2026, submission opens September 25 and closes October 21. Plan your outreach to Carol Rinn at least 8–10 weeks before a window opens.

Think in years, not grant cycles. The average grantee in this portfolio has three consecutive grant periods on record. Position your organization as a long-term partner by being explicit about your classical music education programming's ongoing nature and community impact in Los Angeles.
