Mother, uncle, friend — each of Penn State York’s THON dancers has experienced cancer though the loss of someone they knew well. Justin Neal lost his mother to cervical cancer eight years ago. Yaribeth Ocasio lost her uncle to prostate cancer, and Kelsey Haines lost a friend and former Penn State York student to leukemia. All three will represent their campus in the fight against pediatric cancer at the Penn State IFC/Panhellenic Dance Marathon, affectionately known as THON, Feb. 15-17 at the Bryce Jordan Center.
