John K & Luise V Hanson Foundation

John K & Luise V Hanson Foundation

Launched in 1970 by the late John K. and Luise V. Hanson, the foundation draws its capital from the success of Winnebago Industries, the iconic recreational vehicle manufacturer the couple founded. Now run by their children — John V., Mary Jo Boman, and Paul D. Hanson — the entity maintains a deep philanthropic focus on north-central Iowa, funding arts, youth development, and family recreation projects alongside its investment mandate. The family's broader financial footprint also includes ties to MBT Bank, where John V. Hanson serves as Chairman. The foundation's investment strategy blends direct buyout allocations with a fund-of-funds approach, targeting the natural resources sector as a distinct pillar. A commercial office in Forest City and a residential property in Stuart, Florida, round out the tangible-asset picture. Team leadership is concentrated within the second generation: John V. Hanson serves as President and Director, while siblings Mary Jo Boman and Paul D. Hanson hold director roles. Trustee Robert Hanson, of the third generation, bridges the foundation to broader family holdings through his chairmanship of Hanson Family Holdings and Sinojie Hanson. The foundation operates as a 'Visionary' level sponsor of the Mason City Chamber of Commerce, reinforcing its commitment to the region that housed Winnebago's manufacturing base for decades. What sets the foundation apart structurally is its tight geographic mandate coupled with a multigenerational governance model that integrates both philanthropic grantmaking and private-markets investing under one roof. Rather than outsourcing grant decisions to a separate donor-advised fund or community foundation, the family keeps control within a core group of sibling directors — a structure that resembles a single-family office fused with a private foundation, uncommon for a vehicle of its size.
