Dr. Wantman is a character in the novel Final Destination: End of the Line. He is a doctor who works at St. Stephen's hospital. Wantman was one of the primary head doctors who led the investigation about the Sux racing (which Kate participated in). Despite her sanity slowly withering away, Kate managed to stay calm around Wantman, and he never suspected her of being a culprit, even when he was leading some of his med students on one of his rounds.
