Hanley Family Foundation
The Hanley Family Foundation was established in 1986 in Atlanta, Georgia, by Jack Hanley and his wife Mary Jane. Jack Hanley previously served as Chairman and CEO of Monsanto, the multinational agrochemical corporation. The foundation's narrow mission — funding the diagnosis and treatment of alcoholism, drug addiction, and other substance use disorders — reflects the family's direct experience with these challenges, rather than a general philanthropic posture. The foundation operates as a grantmaking 501(c)(3), directing its approximately $13 million endowment (Altss estimate) entirely toward U.S.-based organizations that hold their own tax-exempt status under Section 501(c)(3). While the foundation does not publicly disclose a full grantee list, its historical ties to treatment providers are deep. The Hanley Center in West Palm Beach, Florida — originally a residential addiction-treatment facility bearing the family name — was at different times operated in partnership with Caron Treatment Centers and Origins Behavioral Health before returning to the control of a separate Hanley Foundation entity. The investment portfolio underlying the endowment is diversified across fund-of-funds and growth strategies, with a professional-network affiliation that includes sponsoring the Hanley Family Foundation Award through Evergreen Climate Innovations. Day-to-day operations are run by the founders' sons: John W. Hanley Jr. serves as Chairman, and Michael James Hanley holds the roles of President and Treasurer. The foundation maintains a deliberately low public profile, with no known social media presence, no LinkedIn company page, and no web presence beyond a simple informational homepage. This architecture — a founder-funded endowment, run by second-generation family members, disbursing to a focused cause area without a dedicated investment staff — places it among the smallest and quietest family foundations tracked. The structural differentiator is the foundation's exclusive tie to a single operational asset: the Hanley Center treatment facility. While the foundation itself is a grantmaker, the wider Hanley family ecosystem includes a residential treatment center in Florida and a separate Hanley Foundation that at times has directly operated clinical programs. This blurring of philanthropic grantmaking and direct service delivery is unusual among small family foundations and means the boundaries between the endowment's financial portfolio, the foundation's grants, and the family's operating assets have shifted over time.

Frequently asked questions
Who runs investment decisions at the Hanley Family Foundation?
The foundation does not disclose a CIO, investment committee, or external OCIO. With an estimated $13 million endowment, investment management is likely handled by the family officers — President and Treasurer Michael James Hanley and Chairman John W. Hanley Jr. — potentially alongside an outsourced advisor, though no advisor relationship has been publicly named.
How does the Hanley Family Foundation source its grantees?
The foundation restricts its giving to U.S.-based 501(c)(3) organizations engaged in substance-use-disorder diagnosis and treatment. It does not operate open calls or publish detailed selection criteria. The concentration of past partnerships with Caron Treatment Centers, Origins Behavioral Health, and the Hanley Center suggests relationship-driven, mission-aligned grantmaking rather than a broad public RFP process.
What is the relationship between the Hanley Family Foundation and the Hanley Center treatment facility?
The Hanley Center in West Palm Beach, Florida, is a residential addiction treatment facility that has been closely tied to the family since its founding. At various points it was operated by the separate Hanley Foundation, and it has had operational partnerships with Caron Treatment Centers and Origins Behavioral Health. The Hanley Family Foundation, by contrast, is a grantmaking vehicle and does not itself operate clinical programs.
Where does the underlying wealth come from?
The endowment originates from Jack Hanley, who served as Chairman and CEO of Monsanto, one of the largest U.S. agricultural and chemical corporations. His compensation and equity from that role, combined with the family's diversified investment portfolio, form the financial base of the foundation.
Does the Hanley Family Foundation maintain philanthropic structures separate from the family office?
Yes, the foundation is a distinct 501(c)(3) vehicle, not a family office. However, the Hanley Center and a separate Hanley Foundation entity sit alongside it in the broader family ecosystem, creating a constellation where grantmaking, program operations, and direct care delivery have historically overlapped.
Is the Hanley Family Foundation structured as a single family office?
No. It is a 501(c)(3) private foundation that makes grants, not a family office. It does not manage the family's broader wealth, offer concierge services, or invest on behalf of multiple family branches. The family's non-philanthropic investment assets appear to reside outside the foundation.
Does the foundation participate in fund commitments or only direct grants?
The foundation's own investment portfolio includes fund-of-funds and growth strategies. However, its operational mandate is exclusively grantmaking to substance-use-disorder organizations; it does not make program-related investments, direct deals, or co-invest in for-profit ventures as part of its charitable activity.
