Dr. Jordan Kenley was the Head of pediatric surgery at Seattle Grace Hospital but died from a heart attack. Kenley died in front of a young patient, while Karev and Bailey tried to resuscitate him, they were unable to. Prescott had been a patient of his for a long time and before he died he had been planning to sign a "wish list" for him from the Make a Wish Foundation. Kenley had lollipops of various colors in his lab coat pocket and just before he died he was talking about whether or not Jackson should get one.
Dr. Jordan Kenley had worked at Seattle Grace Hospital for decades and was the Head of at the time of his death. According to Richard Webber he was a "a son of a bitch" and was good with a scalpel and patients but horrible to his colleagues, competitive, insecure and aggressive, he would not be missed.
