Alpha Delta Pi, or ADPi, was established at WCSU in 1990. ADPi is an international sorority, with over 159 collegiate chapters across the United States and Canada. Their main philanthropic focus is the Ronald McDonald House Charities, an independent American nonprofit organization whose stated mission is to create, find, and support programs that directly improve the health and well-being of children. One event that ADPi is known for is their annual Bingo Night where 100% of the proceeds are donated to the RMHC.
