Theta Delta Chi is proud to recognize our Sigma Deuteron Charge for participating in Humorology, the largest student-run philanthropy event at UW–Madison, benefiting Gio’s Garden and its mission to support children with special needs and their families.

This year, the Sigma Deuteron cast helped raise over $100,000—their most successful year yet. We applaud their commitment to service, leadership, and making a meaningful impact in their community.
