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 $127 million for the Four Diamonds Fund at Penn State Hershey Children's Hospital. THON 2015 took place on February 20th-22nd, 2015 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.
