Covalent Foundation is a private corporation based in RESTON, VA. The foundation received its IRS ruling in 2016. The principal officer is Ellen Fishbein. It holds total assets of $3.9M. Annual income is reported at $5.4M. Total assets have decreased from $5.9M in 2015 to $3.9M in 2025. The foundation is governed by 3 officers and trustees. Tax records are available from 2016 to 2025. The foundation primarily funds organizations in Texas and Virginia. According to available records, Covalent Foundation has made 33 grants totaling $6.8M, with a median grant of $95K. The foundation has distributed between $913K and $3.3M annually from 2020 to 2025. Grantmaking activity was highest in 2022 with $3.3M distributed across 14 grants. Individual grants have ranged from $5K to $1M, with an average award of $207K. The foundation has supported 13 unique organizations. Grants have been distributed to organizations in Texas and Virginia and New York. Contributions to this foundation are tax-deductible.
Covalent Foundation is a small, closely held family private foundation (IRS-administered by Sterling Foundation Management LLC out of Reston, VA, but its giving footprint is entirely Central Texas) led by Mark and Julia McKenzie with Jessica Ziehr as a paid VP/Director. Despite the DB flag `preselected_only: true` and `accepting_applications: true` appearing to conflict, the observed grant pattern — 33 grants across just 8-9 unique organizations over six years, all in the Austin/Travis County area — indicates a highly relationship-driven funder that renews and deepens ties with a tight roster of trusted grantees rather than one that runs a competitive open RFP. Its mission statement (found on covalent.org) is explicit: 'support Central Texas organizations and projects that serve women and youth in need,' spanning pediatric mental healthcare, prenatal support, domestic violence legal aid, youth empowerment/camp programming, foster care, and crisis intervention for women. First-time applicants should not expect an online portal; there is no discoverable LOI form or grants-page infrastructure on the foundation's own site. The realistic path in is a warm introduction — through a grantee's existing board, through Ascension Seton/Dell Children's development staff (who already have the relationship), or through direct outreach via the contact listed on the foundation's IRS filing, Ellen Fishbein c/o Sterling Foundation Management. New organizations should not be Virginia-based or national in scope; every dollar of tracked giving stays in the Austin metro. The clearest 'in' is a program that intersects two or more of the foundation's stated categories at once (e.g., mental health + youth, or domestic violence + crisis intervention) and that can point to institutional partners the foundation already trusts, since Covalent's pattern is multi-year layered support to the same handful of institutions (Dell Children's, Seton/Ascension, CASA of Travis County, Texas Advocacy Project) rather than single grants to new organizations.
Total tracked giving in the DB bundle is $6.82M across 33 grants to organizations, averaging $206,723 per grant; external aggregator data (philanthropy.org) puts lifetime giving at $7.6M across 39 grants to 14 organizations since 2020, with a typical/median grant of $95,000-$100,000. The foundation's own `typical_grant_size` field shows a median of $100,000, range $4,600-$617,929, average $199,312 across its five largest tracked grants. Geographic concentration is extreme: of 33 grants, 23 went to Texas recipients and 9 to Virginia, with essentially all dollar volume landing in the Austin/Travis County area despite the VA administrative address. By recipient, Dell Children's Medical Center Foundation alone absorbed $3.06M across 4 grants (45% of tracked total) for pediatric mental health, maternal-fetal medicine, school nursing/advocacy, and PICU programs. The Seton Fund/Ascension Seton entities (Seton Fund $803K, Ascension Seton Foundation $506K, Seton Medical Center Austin $393K, Seton Medical $257K) collectively total roughly $1.96M (29%), largely for community health centers, obstetric care, and human-trafficking prevention. CASA of Travis County ($760K + $95K) and Texas Advocacy Project ($250K + $100K) round out the next tier at roughly $1.2M combined for domestic violence/foster-child advocacy. Financially, total assets have fallen from $7.2M (2019) to $3.9M (2025), and annual giving has trended down from a 2019 peak of $2.09M to $913,086 in FY2025 — a decline of over 55% — while 2025 revenue collapsed to just $106,911 (from $818,679 the prior year) with no new contributions received since 2023's $2M infusion. This points to a foundation now spending down existing assets rather than being replenished, meaning the available grant pool is shrinking year over year.

Covalent sits in a cluster of nearly identically sized (~$3.9M asset) small family/private foundations classified under the same Philanthropy & Grantmaking NTEE code, most of which — like Covalent — are administered by third-party foundation management firms and disclose no public grants portal. What differentiates Covalent from this peer set is that it is unusually transparent in its public 990 grant history and has a stated, narrow geographic and population focus (Central Texas women and youth), whereas peers like Mckinney, Glenn Family, and the Mcwilliams Trust leave no discoverable focus area or grantee pattern in public data. For a grant seeker, Covalent is the more approachable of this peer group simply because its giving history and mission are traceable — but all six operate as small, closely held vehicles where cold applications are unlikely to succeed absent a warm connection.
The most recent verifiable Covalent Foundation activity in the public record is its FY2025 IRS filing, showing $913,086 in grants paid against a sharply reduced revenue base of $106,911 — down from $818,679 in the prior comparison year — with total assets continuing their multi-year decline to $3.89M. Aggregator data (philanthropy.org) shows 2024-2025 as an active period with renewed/new gifts to Ascension Seton Foundation, Texas Advocacy Project, CASA of Travis County, and Breakthrough T1D (formerly JDRF), suggesting the foundation's current roster of five to six core grantees remains intact even as overall dollar volume shrinks. No leadership changes, new program announcements, or press coverage were found for 2025-2026; the foundation does not appear to issue its own press releases, and news coverage instead comes from grantee-side announcements (e.g., Dell Children's Foundation's own site covering the 2021 PHP gift). No new officers appear in the most recent filings beyond the existing McKenzie/Ziehr leadership team (Mark McKenzie, President; Julia McKenzie, VP/Secretary; Jessica Ziehr, VP/Treasurer). Given the thin public footprint, grant seekers should treat the absence of recent news as normal for this funder rather than a sign of inactivity — its giving continues, just quietly and through existing relationships.
There is no open online application, LOI form, or grants page discoverable on covalent.org or via aggregator sites — Covalent operates as a closed, relationship-driven funder, and organizations new to its network should not expect a standard portal-based process. The single most effective strategy is to build a relationship through one of its existing anchor grantees (Dell Children's Medical Center Foundation, Ascension Seton Foundation, CASA of Travis County, or Texas Advocacy Project) since Covalent's pattern is to fund multiple, escalating gifts to the same trusted institutions over years rather than seed brand-new relationships — six of its documented grants to Dell Children's alone span 2020-2025. Because giving is 100% geographically concentrated in the Austin/Travis County area despite the Reston, VA administrative address, organizations outside Central Texas are not a fit regardless of mission alignment. Proposals should speak directly to the foundation's stated population focus — women and youth in need — and ideally combine two of its six programmatic threads (mental healthcare, prenatal support, domestic violence legal aid, youth empowerment/camps, foster care transition, or crisis intervention), mirroring how its largest grants (e.g., the $1.4M Dell Children's Partial Hospitalization Program gift) bundled clinical, school, and family-support components into one ask. Given the foundation's declining asset base (down from $7.2M in 2019 to $3.89M in 2025) and a 2025 revenue collapse, budget requests should be modest and phased — the observed median grant is $95,000-$100,000, not the $500K+ outlier gifts seen only at the top of its range. The most common mistake would be a cold, generic LOI to the Sterling Foundation Management administrative address; a warmer approach is to identify a board or staff connection at one of the four core grantees and request an introduction, since the foundation's structure (single-family leadership, third-party administrator, no program staff) suggests decisions are made personally by the McKenzie family rather than through a formal review committee.
