Harrison's parents brought him to Nicklaus Children's thinking he had a regular stomach virus, but their world turned upside down when the Emergency Room doctors couldn't find a pulse on their son. Harrison's heart had completely stopped, but he continued to talk and walk.

The ER doctors transferred him to the Cardiac Intensive Care Unit and worked together to diagnose and treat his condition. Thanks to their care, Harrison is back to being active and has participated in the MCH5k for the past three years as a way to give back to the hospital that saved his life.
