Welcome to THON.org, the online home of the largest student-run philanthropy in the world! The Penn State IFC/Panhellenic Dance Marathon, affectionately known as THON, is a yearlong effort to raise funds and awareness for the fight against pediatric cancer. Since 1977, THON has raised more than $137 million for Four Diamonds at Penn State Hershey Children's Hospital. THON 2017 will take place February 17th-19th, 2017, at Penn State's Bryce Jordan Center. We are excited to have you join us as we continue to make strides to find a cure.
