C.A.R.D.S. Closet:

“Denise invited me to help her start C.A.R.D.S. Closet, a free clothing resource for Sun Prairie Area school families, from the start, as a project to teach our children about giving back to the community. We began as a storage shed and have evolved to a storefront, a donation bin, and working relationships with local emergency services. The growth of C.A.R.D.S. Closet exemplifies how Denise and Joe serve the community through their generosity and time. They involve their many friends and associates, giving others the opportunity to serve and improve our community. I look forward to watching the growth of the Greywolf Foundation, because I am confident it will progress with the vision, love, and excellence with which Joe and Denise lead their lives.”

Co-Director, C.A.R.D.S. Closet


Sunshine Place:

"Joe and Denise Wagner, along with Greywolf Partners, have been tremendous supporters of Sunshine Place for many years.  This includes serving as founding members and leaders of C.A.R.D.S. Closet, which provides clothing and personal care items to youth in our community.  The Wagner Family truly embodies a spirit of selfless giving back to their community.  The Greywolf Foundation is a natural extension of this philanthropic determination and will provide an even greater impact for mission-driven organizations in our community."
