Potomac Health Foundation

Potomac Health Foundation is a place-based health funder with $109.5M in assets (FY2024), operating with surgical geographic precision: eastern Prince William County, southeast Fairfax County, and north Stafford County in Northern Virginia — a tri-county footprint serving 390,000+ residents, the majority of them people of color with large Hispanic/Latino and immigrant populations facing compounded barriers to care.

The foundation's giving philosophy centers on health care access for the medically underserved, behavioral health, and the social determinants that drive health outcomes — food security, housing stability, insurance navigation, and now workforce capacity. Their grantee list reveals consistent preference for community-embedded organizations over regional health systems, though anchor institutions like Sentara Northern Virginia Medical Center ($981,390 across 8 grants) and Inova Health Care Services ($480,748 across 4 grants) receive funding when projects explicitly serve underserved Prince William populations.

PHF operates four distinct grant vehicles. The Howard L. Greenhouse Large Grant Program is the competitive, open-door entry point — project grants with awards from $25,000 to $250,000, historically three-year but recently repositioned as one-time grants for the 2026-2027 cycle. This is where first-time applicants must begin. The Health Safety Net (HSN) Program provides annual general operating support to eight pre-selected clinical agencies (invitation-only). The Management Assistance Program (MAP) funds capacity building for existing partners (invitation-only). Discretionary Grants address emerging needs flexibly.

The relationship progression for competitive applicants follows a two-stage gate: first, a Letter of Intent that PHF uses to filter before inviting full applications. Organizations performing well and receiving a full proposal invitation typically undergo a site visit as part of due diligence. PHF's top grantees have received 8-12 grants each across multi-year periods — Greater Prince William Community Health Center has 12 grants totaling $1.07M, Northern Virginia Family Service has 11 grants totaling $925K — demonstrating that entry through the competitive program followed by consistent performance is the pathway to invitation-only status.

PHF functions explicitly as a community convener, not just a check-writer. Demonstrating fluency in the local health ecosystem — referencing the Community Health Coalition of Greater Prince William, naming partner organizations active in the service area, and acknowledging existing safety-net capacity — signals the genuine regional embeddedness the foundation seeks in its grantees.

Across 280 total grants in the grantee database totaling $19.9M, PHF's per-grant economics are more modest than its $109M asset base might suggest. The typical grant size shows a median of $41,310 and an average of $56,943, ranging from $1,500 to $202,000 per individual award. The Howard L. Greenhouse Large Grant Program caps at $250,000 per year; historical awards from 2016 data showed a range of $19,323 to $257,000 with 25 recipients sharing $2.69M. The real financial depth comes through multi-year relationships: top grantees have accumulated $685,000 to $1.37M over multiple cycles.

Annual giving has fluctuated significantly. FY2020 saw an outlier $12.1M in total giving — driven by COVID-19 emergency response grants distributed across behavioral health, food security, and primary care grantees. FY2021 returned to $6.4M; FY2019 was $6.4M; FY2018 was $7.0M. FY2022 dropped sharply to just $1.5M in total giving, coinciding with an executive director transition (compensation data shows Steven Liga at $30,195 vs. Susie Lee's typical $142-147K), likely representing a pause in grant cycles during leadership change. FY2023 recovered to $7.8M ($6.4M in grants paid directly). FY2024 shows $9.7M in revenue but total giving is not yet filed, suggesting continued activity.

Program area analysis from the grantee database reveals behavioral health and mental health as the largest cluster by dollars: Youth For Tomorrow ($1.37M, 8 grants), Northern Virginia Family Service ($925K, 11 grants), SCAN of Nova ($287K), and Inova behavioral health expansion ($481K) anchor this category. Primary and community health care forms the second tier: Greater Prince William Community Health Center ($1.07M, 12 grants), Lloyd F. Moss Free Clinic ($657K), Catholic Charities Mother of Mercy ($390K), and Mason & Partners Clinic ($115K). Social determinants of health — food security, housing repairs, SNAP access, Medicaid navigation — constitute a growing third tier, with Capital Area Food Bank ($244K), Northern Virginia Food Rescue ($298K), Project Mend-A-House ($198K), and Virginia Community Food Connections ($119K) all receiving multi-year grants.

Geographic concentration is overwhelmingly Virginia: 247 of 280 grants (88%) went to Virginia organizations; 29 (10%) to DC-based entities such as the Community Foundation for Northern Virginia and Young Invincibles. Illinois, Massachusetts, Maryland, and Minnesota each received one grant — rare outliers likely tied to national-scope partners.

PHF's defining differentiation among similarly-sized health foundations is extreme geographic precision. While peer foundations typically serve a metro region or statewide scope, PHF explicitly defines its service area down to individual communities — Woodbridge, Dale City, Lorton, Dumfries, Garrisonville, Quantico, Occoquan — within a tri-county footprint. This hyper-local focus gives the foundation unusually deep knowledge of grantee organizations and places significant weight on demonstrated community presence. PHF's open RFP through the Howard L. Greenhouse program is relatively more accessible than peers that operate entirely by invitation, but geographic eligibility is non-negotiable: organizations serving adjacent Northern Virginia communities outside the defined tri-county area are ineligible regardless of mission alignment.

The most significant recent development is the December 15, 2025 opening of the 2026-2027 Howard L. Greenhouse grant cycle, with applications confirmed open and guidelines published. Grant listing databases record the application deadline as March 30, 2027, giving applicants an extended runway for the full proposal stage. Critically, this cycle explicitly frames awards as one-time grants rather than the historically renewable three-year structure — a structural change that applicants must account for in project design.

For the 2025-2026 cycle, the Board of Directors approved two standalone strategic priorities: Improving Individual Health for the medically underserved, and Healthcare Workforce Development — with the latter representing a meaningful new emphasis not historically prominent in earlier grant cycles. The foundation is simultaneously developing a new multi-year strategic plan, suggesting further evolution of priorities is likely through 2026-2027.

Executive Director Susie Lee has led the foundation since at least FY2021, with compensation rising from $113,925 (FY2022, a partial year) to $142,110 (FY2023) to $147,321 (most recent filing). Marion M. Wall continues as Board Chair; Carol S. Shapiro MD MBA serves as Vice-Chair; R. Michael Sorensen as Treasurer. The board includes physicians (Shapiro, Ala S. Mortazavi MD) and credentialed academics (Sarah Pitkin PhD, Sam Hill EdD, Phyllis Morgan PhD, Clarice Toran MEd), reflecting a culture that values evidence-informed program design. The 2023-2024 grant cycle awarded 14 new grants totaling $899,731 out of 47 total active grants that year.

Lead with geography, always. The single most important principle for PHF applications is demonstrating that your program serves the defined tri-county service area. Generic 'Northern Virginia' footprints will not succeed. Name zip codes, neighborhoods, and school districts. Reference the demographic reality — majority-minority Prince William County with large Hispanic/Latino and uninsured immigrant populations — and tie your program's target population directly to those communities.

Treat the Letter of Intent as a proposal, not a placeholder. PHF staff use the LOI to screen which organizations receive full proposal invitations. A strong LOI names the specific health problem with local data (Prince William County Health Department statistics, Community Health Needs Assessment findings, or county-level census data), describes the intervention concisely, demonstrates organizational credibility and community embeddedness, and aligns explicitly with the current cycle's stated priorities. Vague LOIs do not advance.

Align to named priority areas. The 2026-2027 cycle lists eight explicit funding categories: community wellness, behavioral healthcare and substance abuse services, oral health for vulnerable populations, primary healthcare clinics, prescription medication access, food security, health insurance assistance (Medicaid navigation), and nonprofit capacity building. Frame your project within one of these categories explicitly — do not make PHF draw the connection.

Healthcare Workforce Development is an underserved niche with a clear competitive advantage. This priority has few existing PHF grantees compared to the crowded behavioral health and primary care fields. Organizations training community health workers, dental hygienists, bilingual care navigators, or clinical staff serving the tri-county area should lead with this angle in 2025-2026 and 2026-2027 cycles.

Build a 100% direct-cost budget. PHF explicitly excludes indirect costs and will not fund fundraising events, debt retirement, or programs lacking diverse funding sources. Document all other revenue sources to demonstrate fiscal health and diversification. Budgets should cover personnel, supplies, contracted services, and participant costs only.

Invest in the relationship before the deadline. Attend PHF-convened convenings and Community Health Coalition of Greater Prince William County meetings. Staff familiarity with your organization and its work in the community creates meaningful context for LOI review. PHF functions as a regional health convener and values organizations that participate in collective problem-solving year-round.

Timing: Monitor the foundation's website starting in October-November each year for RFP announcements. The 2025 cycle had a February 21 LOI deadline; the 2027 cycle closes March 30 — suggesting a late winter/early spring submission window is standard.
