Full circle with Four Diamonds

Charlie Karchner has attended THON for 16 years, and has even been on the floor of the 46-hour dance marathon. But this year will bring a whole new THON experience for him as he takes on the role of dancer. Karchner is a survivor of acute lymphoblastic leukemia, and he and his family were supported by THON while he underwent treatment.
