Her parents divorced when she and her brother were still young, while still remaining friends. She also practised swimming and baseball. When Trinidad was ten years old, her father was killed in the September 11 attacks; he had worked as a telecom analyst for the firm Cantor Fitzgerald at the World Trade Center. He was on the 103rd floor of the North Tower when it collapsed. Trinidad's mother, Monique Ferrer, approached StoryCorps with the story of how she and her husband had met and what she experienced on the day of the attacks with his death, which StoryCorps used to create a short cartoon titled Always a Family, as a way of honoring his memory.
