Last October, more than 300 guests gathered at the Four Seasons Chicago for the 4th annual Hoosier Ball to benefit the Lyon Family Foundation, which raised nearly $500,000 for the Leukemia and Lymphoma Society. Partygoers donned extravagant masquerade masks, sipped specialty cocktails, and nibbled on delicacies from a raw bar, dim sum stations, and Italian-inspired fare. Special host Bill Rancic joined Lyon Family Foundation Executive Director Alexandra Lyon Singer to lead the live auction featuring exotic trips, luxury art, and exclusive private dinners sponsored by Ferrari Lake Forest. DJ Matt Roan and performances by Elan Artists rounded out the evening as guests took to the blackjack, roulette, and poker tables and enjoyed handcrafted desserts by the Four Seasons acclaimed Chef, Juan Gutierrez. lyonfamilyfoundation.org
