Hippo Heaven: Zoo Ball 2021

Presented by 2021 Zoo Ball Chair, Robert Dohmen

August 14, 2021

Milwaukee County Zoo

The glamour, adventure and beauty of Zoo Ball are back. This year’s theme is all about hippos in honor of the Dohmen Family Foundation Hippo Haven. There will be cocktails, hors d’oeuvres, a silent auction, gourmet dinner, music and much more. This is the Zoological Society’s largest fundraiser of the year, and for the first time, we are inviting guests at home to participate in the online auction. The auction will open the first week of August and will close the night of Zoo Ball. Anyone can bid on items such as paintings by the Zoo animals, dining packages, sporting memorabilia and more.

Individual tickets start at $350. Please contact Special Events at with any questions or to reserve a table.
