Gabe is a very sarcastic and cynical person. Unlike the other members of the Trauma Team, he is less open about wanting to save lives. He notes that he isn't very good with the "mushy" stuff, implying that his constant lack of positive emotions caused him to drift apart from his family. Nevertheless, when he realizes that his patients may have very grave conditions, he doesn't hesitate to do everything in his power to give them a complete diagnosis. Always seen with a cigarette, has a ex wife.
