Since 1998, she has been a presenter on "Globe Trekker", and has hosted episodes on Vietnam, Greece, Italy, Ghana, Indonesia, Sri Lanka, China, India, Egypt, and Japan. She hosted the New England episode, where she herself attended university. Production of this episode was difficult for her and the crew, as filming had just begun as the 9/11 attacks occurred. She also presented "Treks in a Wild World", a show which emphasizes ecotourism and history and also has adventure elements. Before joining Pilot Productions, McCormick worked behind the scenes on "The News with Brian Williams" on the CNBC and MSNBC cable networks.
