Mannheimer Foundation Inc.

Mannheimer Foundation Inc. is a private operating foundation (IRS foundation code 03) — a fundamentally different structure from a traditional grantmaking foundation. Rather than distributing funds to outside organizations, Mannheimer directs virtually all of its resources toward operating its own scientific enterprise: two nonhuman primate research facilities in Homestead and LaBelle, Florida, housing more than 4,000 rhesus macaques, cynomolgus macaques, and hamadryas baboons. This distinction is critical for any organization considering an approach: the foundation has explicitly stated it makes contributions only to preselected charitable organizations and does not accept unsolicited requests for funds.

Founded in 1969 and AAALAC-accredited, Mannheimer's 55+ year institutional history reflects deep expertise in nonhuman primate medicine, reproduction, and biobehavioral research. Its IRS-stated mission — to study and conduct research on human behavioral, sociological, and psychological patterns — is executed through primate husbandry, veterinary care, and research services sold to pharmaceutical companies, government agencies, and universities. Revenue in FY2024 was $9.67M, drawn almost entirely (~93%) from service fees, not donor contributions.

Governance operates on two tiers. A small administrative board — Dennis Donato (President, $12,000/year), Diane Donato (First Vice President, $12,000/year), and Dr. Theodore I. Malinin (Medical Advisor, $12,000/year) — provides organizational oversight through the administrative office at Donato Hayes & Co. CPAs LLC. Day-to-day scientific operations are led by Director Pablo Morales ($279,992), with Assistant Directors Wesley Burnside ($151,390) and Gregory Parmenter ($141,493) and Veterinarian Tinika Johns ($110,492) running the facilities.

For first-time prospective partners, there is no grant application process. However, meaningful engagement channels do exist. Veterinary schools can pursue offsite elective arrangements (Ohio State has done exactly this). Pharmaceutical companies, NIH-funded investigators, and federal agencies requiring nonhuman primate research capacity can approach Mannheimer as a contracted research partner or service provider. Any outreach should lead with scientific credentials, USDA/AAALAC compliance, and alignment with biobehavioral research — not a funding ask. Organizations seeking traditional grant dollars should look elsewhere entirely.

Mannheimer Foundation's financial profile is that of a self-sustaining research enterprise, not a philanthropic grantmaker. The IRS confirms grants paid as $0 for every year on record — all expenditures represent direct operational program costs (animal care, veterinary staffing, facilities maintenance) rather than external grants to other organizations.

Program expenditures have grown steadily over the past decade: - FY2011: $6.51M program expenses, $18.95M assets - FY2012: $6.33M program expenses, $18.99M assets - FY2019: $6.49M program expenses, $21.81M assets - FY2020: $6.43M program expenses, $21.99M assets - FY2021: $6.26M program expenses, $21.62M assets - FY2022: $6.98M program expenses, $21.30M assets - FY2023: $7.48M program expenses, $23.26M assets - FY2024: $8.6M program expenses, $23.92M assets

This represents a 36% increase in program spending from FY2012 to FY2024. The sharpest jump occurred between FY2022 and FY2023 (+7.2%), coinciding with a 42% revenue surge ($6.5M to $9.22M), strongly suggesting new multi-year research service contracts entered that period.

The revenue model is distinctive and nearly devoid of philanthropy. FY2024 breakdown: approximately $9.0M (93.2%) from service fees and other operating income; $219,760 (2.3%) from investment dividends; $438,749 (4.5%) from asset sales. Contributions received were $0 in FY2024, $0 in FY2023, $0 in FY2022 — and only minimal in prior years ($8,538 in FY2021; $40,697 in FY2020; $181,334 in FY2019).

Total assets have grown from $18.95M in FY2011 to $23.9M in FY2024, a modest 26% over 13 years, consistent with a foundation that reinvests surplus into operations rather than building an endowment. Staff compensation reflects genuine operational scale: top staff compensation alone exceeds $800K annually in FY2024. The median grant size is not applicable; the foundation's entire spending profile is program-operational.

The database provided no direct peer foundations for Mannheimer. The following comparison uses thematic peers — private foundations focused on behavioral biology, neuroscience, or biomedical research — ranging from operating foundations to grantmakers of comparable asset scale. Figures marked "est." are drawn from publicly available filings and secondary sources.

Mannheimer stands apart in one critical way: it is a private operating foundation that allocates its entire budget to running its own programs, while Whitehall, Grass, and McKnight operate as grantmakers distributing funds externally. Mannheimer's annual program spend ($8.6M) dramatically exceeds Whitehall's grantmaking (~$1.5–2M) because Mannheimer funds facilities, veterinary staff, and over 4,000 research animals — not external investigators.

For researchers seeking external grant funding in behavioral or neuroscience fields, The Whitehall Foundation (Palm Beach Gardens, FL) and the McKnight Endowment Fund are the actionable alternatives. Mannheimer's value to the research community is as infrastructure and expertise, not as a funding source.

The most recent publicly available Form 990-PF for FY2024 was filed November 12, 2025. It documents the foundation's highest recorded program expenditures ($8.6M) and revenue ($9.67M), continuing two consecutive years of significant growth. Program disbursements rose from $7.48M (FY2023) to $8.6M (FY2024), a 15% single-year increase.

Leadership compensation data from FY2024 reveals a professional operational team at compensation levels consistent with a mid-sized research institution: Director Pablo Morales ($279,992), Assistant Director Wesley Burnside ($151,390), Assistant Director Gregory Parmenter ($141,493), and Veterinarian Tinika Johns ($110,492). This represents a substantial staffing investment that was not visible in earlier database records reflecting only the $12,000 board officer salaries.

No press releases, news announcements, or public statements from the foundation were found for 2025 or 2026. The foundation maintains a low public profile consistent with a contracted research services provider rather than a publicly fundraising nonprofit.

External institutional relationships remain active: Ohio State University's College of Veterinary Medicine lists an ongoing offsite elective at the foundation, and the AALAS career center shows active employment listings. Animal welfare monitoring organization SAEN (Stop Animal Exploitation Now) maintains a Florida facility report page for the foundation, reflecting ongoing regulatory scrutiny common to USDA-regulated primate research facilities.

The foundation has operated continuously since 1969 with no reported leadership crises or regulatory violations in the available public record.

The most important tip for any organization approaching Mannheimer Foundation Inc. is to understand precisely what kind of entity it is before making contact. This is a private operating foundation — one that funds and runs its own scientific programs exclusively. It explicitly does not accept unsolicited funding requests. Approaching it as you would a community foundation or research grantmaker will waste time and yield no results.

That said, legitimate engagement pathways exist for specific types of organizations:

For veterinary schools and training programs: The foundation offers hands-on training for veterinary students and postgraduate veterinarians in nonhuman primate medicine. Ohio State's offsite elective is the established precedent. To pursue a similar arrangement, contact via the website form at mannheimerfoundation.org and specify your institution name, USDA animal research registration number, and the precise training objectives — primate handling, surgical techniques, reproductive medicine, or biobehavioral observation protocols. Demonstrating existing IACUC approval and AAALAC compliance signals serious institutional capacity.

For pharmaceutical and biomedical research institutions: Mannheimer functions as a contracted research services provider. Approach this as a vendor negotiation, not a grant application. Prepare a one-page scientific brief: species required (rhesus macaque, cynomolgus macaque, or hamadryas baboon), animal count, study duration, procedures needed, and welfare oversight plan. Reference AAALAC accreditation prominently.

For federally funded investigators: NIH grantees requiring primate research infrastructure can engage Mannheimer as a subcontractor under an existing federal award. Highlight USDA Animal Welfare Act compliance and prior primate research experience in initial outreach.

Timing and contacts: There is no grant cycle or application deadline. The primary contact point is the website form; the phone number (305) 245-1551 connects to the Homestead facility. Administrative correspondence may route through Donato Hayes & Co. CPAs LLC. For scientific discussions, target Director Pablo Morales or Veterinarian Tinika Johns by name.

Critical mistake to avoid: Do not submit a standard grant proposal narrative, budget justification, or LOI in philanthropy format. This organization has no mechanism to receive or evaluate such materials.
