No. 6: A record-setting gift

John and Carolyn Sonnentag had already given $10 million for construction of a new center to replace UW-Eau Claire’s aging Zorn Arena. In early December they raised their gift to $70 million. The Sonnentag Events Center and the John and Carolyn Sonnentag Fieldhouse will be part of the County Materials Complex, scheduled to open in 2024.
