Children's Hospital of Wisconsin, founded 1894, is the state's only independent pediatric health system.
Children's Hospital of Wisconsin
Children's Hospital of Wisconsin was founded in 1894 and has since grown into the state's sole independent health system dedicated exclusively to children and teens. Board Chair Patrick Hammes of Hammes Partners and board member Kaitie Gannett, Head of Investments at Atlantic Harbor Group, guide the system's financial strategy alongside CFO Marc Cadieux. The organization functions as both a care provider and an asset owner, with its investment portfolio operating in support of its clinical mission. The system's strategy integrates mission-related and total-return investing. It holds a diverse asset base that includes healthcare real estate — the Milwaukee hospital campus at 9000 W. Wisconsin Avenue, a Fox Valley hospital in Neenah, and commercial office buildings in West Allis and Wauwatosa — as well as a Caribbean Investment Portfolio. While allocations to traditional equity and fixed income are not publicly detailed, the presence of a family-office professional on the board suggests a rigorous, multi-asset approach. The Medical College of Wisconsin serves as a core academic partner, anchoring the Children's Research Institute. Children's Wisconsin operates multiple campuses, employs a dedicated transport fleet including a Flight for Life helicopter and mobile intensive care units, and supports its work through the Children's Hospital of Wisconsin Foundation. In the last two years, the system maintained its position as a U.S. News & World Report-ranked children's hospital in five specialties while earning the Gallup Exceptional Workplace Award for its 16th consecutive year. CFO Marc Cadieux also serves as Board Chair of Special Olympics Wisconsin, reflecting the system's community-embedded structure. Its governance architecture is the structural differentiator. Unlike most endowed healthcare foundations that operate as grantmakers, Children's Wisconsin is an integrated delivery system that directly manages clinical operations, research facilities, and a diversified investment portfolio. A board composed of real estate and family-office investors signals a hybrid posture: long-term asset stewardship with the operational discipline of a private-sector holding company, all in service of pediatric care.

Frequently asked questions
Who governs the investment portfolio at Children's Hospital of Wisconsin?
Board Chair Patrick Hammes, Managing Principal of Hammes Partners, and board member Kaitie Gannett, Head of Investments at Atlantic Harbor Group, are the named fiduciaries overseeing the hospital's financial assets. CFO Marc Cadieux handles day-to-day financial operations. This governance structure places real estate and family-office investment expertise at the center of asset allocation decisions.
Does Children's Hospital of Wisconsin operate more like a foundation or an operating healthcare provider?
It is primarily an operating entity, not a grantmaking foundation. The system directly manages hospitals, clinics, a research institute, commercial real estate holdings, and a transport fleet. The investment portfolio exists to support and sustain these operations. The affiliated Children's Hospital of Wisconsin Foundation handles philanthropic giving and is structurally separate from the operating entity.
What is known about the Caribbean Investment Portfolio?
Specific holdings and the portfolio's objective are not publicly disclosed. It is recorded as a distinct asset within the health system's broader investment structure. Without additional fund documentation or public filings, its composition, mandate, and performance remain private (Altss estimate).
How is the Medical College of Wisconsin tied to the hospital's investment strategy?
The Medical College of Wisconsin is the hospital's principal academic and clinical affiliate, not an investment partner. They collaborate through the Forward Pediatric Alliance and Children's Research Institute. The affiliation ensures clinical research and physician staffing, but investment decisions are made by the hospital's governing board independently.
What is the role of the Children's Hospital of Wisconsin Foundation?
The Foundation is a separate legal entity that raises and manages philanthropic gifts to support the hospital's patient care, research, and community programs. It provides an additional vehicle for donor capital but is distinct from the hospital's internally managed investment portfolio.
Does the hospital disclose its total assets under management or annual deployment figures?
No. Children's Hospital of Wisconsin does not publish AUM, deployment, or an annual investment report. Its portfolio size is undisclosed.
What is the health system's posture on environmental, social, and governance investing?
The system maintains an Inclusion, Diversity and Equity program embedded in its corporate operations and has committed to community health partnerships with organizations like Special Olympics Wisconsin and the Green Bay Packers. However, it publishes no formal ESG investment policy or dedicated impact-investing mandate for its portfolio.
