The Denise & Michael Riebe Foundation focuses its small, targeted giving on supporting higher-education arts programming in the Tampa Bay area, specifically directing funds to the University of South Florida. Their grants are narrow in scope and purpose, aimed at sustaining or enhancing the USF Art Department rather than broad philanthropic diversification.
Denise & Michael Riebe Foundation Inc gives in a tightly targeted way, with repeated support for arts programming at the University of South Florida. The largest recent grants in the record are two $8,000 awards, one in 2024 and one in 2023, both to USF Foundation for support of the USF Art Department. That recurring line of giving sits alongside smaller awards to Tampa arts organizations such as Tampa Regional Artists and the Tampa Museum of Art, suggesting a local arts emphasis centered on higher education and the surrounding arts community. Their recent grant history also reaches beyond the arts into environmental work, women’s services, aviation education, food relief, and safety-related programs. Grants to Civil Air Patrol, Centre for Women, Feeding Tampa Bay, World Central Kitchen, and BE SAFE Inc show a foundation that favors modest, purpose-specific awards rather than broad unrestricted support. The record includes recipients in Tampa, St Petersburg, Palm Harbor, Osprey, Plant City, Nashville, and Washington, DC, but the pattern remains selective and program-focused. This is a small foundation with a clear preference for defined projects and recurring institutional partners.
Arts support is the clearest thread in the recent record. Denise & Michael Riebe Foundation Inc gave $5,000 to Tampa Regional Artists in 2025 for arts, and $5,000 to Tampa Museum of Art in 2024 for arts. It also made two $8,000 grants to USF Foundation for support of the USF Art Department in 2024 and 2023, reinforcing a sustained interest in visual arts programming. Outside the arts, the foundation has funded environmental and conservation work through grants such as $4,675 to Friends of Warner Park for environmental work in 2025 and $4,000 to Conservation Fndn of the Gulf Coast for environmental conservation in 2025. It has also supported food relief with $4,000 to World Central Kitchen and $3,000 to Feeding Tampa Bay in 2025, and aviation education with $4,000 to Civil Air Patrol for aviation education, emergency services, and cadet programs.
Typical grants are small: the p25 is $1,188, the median is $2,000, and the p75 is $4,000. The recent record shows repeated support for several recipients across multiple years, including USF Foundation, Centre for Women, Civil Air Patrol, Conservation Foundation of the Gulf Coast, and Tampa Bay Reforestation and Environmental Effort. That points to recurring relationships rather than one-off gifts. The foundation does make grants to individuals, and it does not make program-related investments. The pattern is best described as targeted operating or program support for a limited set of local and regional recipients.

Highly concentrated and local: very few grants, repeat funding to a single grantee (USF Foundation), modest dollar amounts with a focused programmatic purpose.
Notable grantees: USF Foundation (supporting USF Art Department)
Most grants land in Florida, and 75% of giving goes to recipients in the foundation’s HQ state. Tampa appears frequently, with grants to USF Foundation, Tampa Regional Artists, Tampa Museum of Art, Centre for Women, Feeding Tampa Bay, and Civil Air Patrol. Other Florida recipients include St Petersburg, Palm Harbor, Osprey, Plant City, and Lakeland. Outside Florida, the record includes Nashville, Washington, DC, Kalamazoo, and a single grant in Poland, reflecting a regional footprint with a few out-of-state exceptions.
The clearest pattern is arts support, especially higher-education visual arts at the University of South Florida. Recent grants also show support for environmental and conservation work, women’s services, food relief, aviation education, and safe boating programs.
Yes. The record includes repeated grants to USF Foundation in 2023 and 2024, Centre for Women in 2023, 2024, and 2025, Civil Air Patrol in 2023, 2024, and 2025, and several environmental groups across more than one year.
The grant-size distribution is small and concentrated: the 25th percentile is $1,188, the median is $2,000, and the 75th percentile is $4,000. Recent gifts above that range include $5,000 and $8,000 awards.
Florida receives the bulk of grants, with 75% going to recipients in the HQ state. Tampa is the most visible city in the record, but the foundation also gives in St Petersburg, Palm Harbor, Osprey, Plant City, and Lakeland, plus a smaller number of grants outside Florida.
A defining arts grant is the pair of $8,000 awards to USF Foundation in 2024 and 2023 for support of the USF Art Department. The foundation also gave $5,000 to Tampa Regional Artists in 2025 and $5,000 to Tampa Museum of Art in 2024.
