Kleenex Alert: Meet 6 year old John Oliver. His friends and family call him JO. He just received a heartwarming welcome back to school after his battle with Leukemia.

JO was only 3 when he was diagnosed with Leukemia on Halloween in 2017. He spent 3 years battling the disease and was finally cleared to go back to school after finishing his chemo treatments.

He went back to school thinking it would just be an ordinary day, but instead was welcomed back with a standing ovation from the school, as students lined the hallway they cheered for JO, and I think the look on his face speaks for itself!
