Hall Halliburton Foundation Inc.

Hall-Halliburton Foundation Inc. is one of the most selective private funders in the Southeast — not because of a rigorous multi-stage review process, but because there is no application process at all. The foundation operates on a purely relationship-driven, invitation-only model, and its own website states plainly that submitting an unsolicited request will permanently exclude your organization from future consideration. This is not rhetorical boilerplate; it is the operating policy.

Founded in 1977 and based in Jacksonville, Florida (with apparent recent operational activity in Oro Valley, Arizona), the foundation controls approximately $32.5M in investment assets and distributes $1.5–2.3M annually. The leadership team — President Randolph B. Mahoney, Vice President R. Bruce Shealy, and Secretary/Treasurer Frances L. Moulder — has been stable for over a decade. All three receive only modest compensation ($20,196 each for Mahoney and Moulder in FY2024; $12,623 for Shealy), signaling genuine mission-driven philanthropy rather than a professionalized grant operation with a development staff.

The grantee portfolio reveals the foundation's true character: personal passions made philanthropic. K9s For Warriors (the largest cumulative recipient at $500K total), Flathead K9 Foundation, Lab Retriever Rescue, Help Four Paws, and Retirement Home For Horses together demonstrate a deep commitment to animal welfare, particularly military service dogs. The AOPA Foundation ($400K total in documented grants) and Stonehende Aviation Museum suggest aviation is a personal leadership interest. Whitefish Legacy Partners ($400K cumulative) and Whitefish Community Aquatics Healing Center ($250K cumulative) reflect a meaningful personal connection to the Flathead Valley of Montana.

For first-time applicants, the pathway is entirely social, not transactional. The foundation publishes no grant deadlines, program priorities, or eligibility criteria because those mechanisms do not govern how it gives. Organizations with natural connections to leadership's documented interests — Jacksonville community organizations, Montana conservation or recreational causes, K9 and veteran service programs, or aviation-related nonprofits — should invest in building genuine relationships with current grantees or community networks that overlap with leadership's known circles. A warm introduction from an existing grantee is the functional equivalent of an invitation to apply. Once a relationship is established, the application format is informal by design: per IRS filings, a simple "WRITTEN REQUEST" is all that is expected — a direct, personal letter is far more appropriate than a polished foundation proposal.

Hall-Halliburton Foundation has maintained a remarkably stable financial profile for over a decade, anchored by approximately $32.5M in investment assets that generate $700K–$950K in annual net investment income plus supplemental asset sales. Annual charitable disbursements have ranged from $1.21M (FY2019) to $2.04M (FY2022), with FY2024 at $1.53M sitting in the midrange. The foundation's giving represents roughly 4–6% of total assets annually, broadly consistent with private foundation payout requirements.

Grant sizing has shifted toward concentration over time. Across 46 tracked awards in the database, the median grant is $25,000 and the historical average is $54,457. However, FY2024 data shows just 15 grants averaging $102,227 each — nearly double the historical average — reflecting a preference for deepening relationships with proven partners over broadening the grantee pool. Individual grant amounts in the database range from $500 (Stonehende Aviation Museum) to $250,000 per award cycle (K9s For Warriors and Whitefish Community Aquatics Healing Center). The largest multi-year relationships — K9s For Warriors at $500K total, AOPA Foundation and Whitefish Legacy Partners at $400K each — represent sustained commitments across at least two documented grant cycles.

Geographic distribution is clear-cut: Florida receives roughly 55% of total giving, concentrated in the Jacksonville metro area (24 of 46 tracked grants). Montana receives approximately 20%, focused on the Whitefish/Flathead Valley region (12 of 46 grants). Maryland accounts for about 19%, driven by Retirement Home For Horses in Woodbine, MD. The remaining 6% is spread across New Jersey, New York, Virginia, and Georgia.

Thematic allocation by dollar value breaks down approximately as follows: animal welfare (K9 service dog organizations, horse rescue, dog rescue) accounts for an estimated 35–40% of total disbursements. Aviation-affiliated causes represent roughly 20–25%. Montana outdoor recreation and conservation receives about 15–18%. Jacksonville community services (youth, arts, social services, faith-based) account for approximately 10–15%. Education — primarily Florida university foundations (UNF, FSU, University of Florida) — represents under 5% by dollar value despite appearing frequently by grant count. The foundation receives zero external contributions, meaning its giving capacity is entirely self-sustaining from investments.

Hall-Halliburton Foundation occupies a distinctive niche among Florida private foundations: mid-sized assets (~$32.5M), deeply personal grantmaking guided by leadership interests, and strict invitation-only access with no formal intake mechanism. The table below compares it to foundations with similar geographic profiles or giving scales. All peer figures are approximate, drawn from publicly available 990-PF filings and may reflect different fiscal years.

Hall-Halliburton's per-grant average ($102K in FY2024) significantly exceeds what comparable-sized foundations typically pay, reflecting its concentrated relationship model and small grantee pool. Unlike the Jessie Ball duPont Fund or the Arthur Vining Davis Foundations — both of which operate structured LOI or invitation processes with defined program areas — Hall-Halliburton has no formal intake mechanism and publishes no giving priorities. Its thematic focus on animal welfare and aviation is unusual among Florida foundations at this asset level, suggesting it functions more like a family foundation than an institutionalized grantmaker. Organizations pursuing multiple Jacksonville funders should develop differentiated positioning for each rather than submitting identical proposals.

The FY2024 990-PF (the most recent available) shows $1,775,781 in total charitable expenses, of which $1,533,413 went directly to 15 grantees — a 28.6% decline in grant count from FY2023's 21 awards. The AOPA Foundation received $500K in FY2024, its largest single-year award from this foundation on record. The Tacamo Foundation emerged as a significant new grantee at $220K — the Tacamo mission involves airborne nuclear command-and-control aircraft, connecting the military and aviation themes that run throughout this foundation's giving. Downtown Ecumenical Services received $200K, reinforcing its role as a Jacksonville anchor grantee, and Retirement Home For Horses received $150K.

Leadership compensation in FY2024 remained modest: Randolph B. Mahoney (President) and Frances L. Moulder (Secretary/Treasurer) each earned $20,196; R. Bruce Shealy (Vice President) earned $12,623. These figures have grown incrementally from $16,782 and $12,232 in the earliest tracked filings, consistent with a lean founder-operated structure with no dedicated program staff.

A potentially significant operational development is the apparent shift of the foundation's registered address from 2939 Yale Ave., Jacksonville, FL 32210 to Oro Valley, Arizona, while the formal mailing address (PO Box 37021, Jacksonville, FL 32236) and phone number (904-635-2613) remain unchanged. No public announcement accompanied this change. The foundation has no social media presence and its single-page website has not been substantively updated in recent years.

The single most important piece of advice for approaching Hall-Halliburton Foundation is this: do not apply without an explicit invitation. The foundation's website — which consists of a single page — contains one substantive policy statement: receiving an unsolicited request will permanently exclude your organization from future consideration. This is not boilerplate language; it is the entire access policy.

The pathway to an invitation runs entirely through relationships. Begin by mapping your organization's network against the current grantee roster: K9s For Warriors (Ponte Vedra Beach, FL), AOPA Foundation (Frederick, MD), Downtown Ecumenical Services (Jacksonville, FL), Retirement Home For Horses (Woodbine, MD), Art With A Heart (Jacksonville, FL), Whitefish Legacy Partners (Whitefish, MT), and JASMYN (Jacksonville, FL). A warm referral from any of these organizations' executive directors is the most reliable pathway to an initial expression of interest from leadership.

Thematic alignment is critical. The most favorably positioned organizations serve one or more of these areas: veteran-facing programs (particularly K9 service dog organizations), general aviation advocacy or education, animal rescue and welfare, Montana conservation or outdoor recreation, or Jacksonville community arts and social services. Organizations spanning two of these categories — for example, a veteran-serving aviation training program or a K9 rescue organization with a Jacksonville presence — are especially well-positioned.

If you receive an invitation or expression of interest, respond with a written letter, not a formal grant application. The IRS filings describe the process simply as "WRITTEN REQUEST." That letter should be 1–2 pages, addressed to President Randolph B. Mahoney at PO Box 37021, Jacksonville, FL 32236. Include: the specific dollar amount requested (anchor around $100K for an established relationship; $25K–$50K as a first ask); a concise organizational overview; a focused description of how funds will be used; a one-page budget; and your IRS 501(c)(3) determination letter. Use direct, personal language — development-office boilerplate will feel tone-deaf to this leadership team.

Timing is flexible — there is no deadline calendar or announced review cycle — but allow three to six months for a decision. Follow up no more than once. The three-person leadership team reviews grants entirely on its own timeline.
