Bommentre teamed up with Kimberly Navarro after a tryout in April 2005. They won the bronze medal at the 2008 U.S. Championships, and were chosen to represent the United States at the 2008 Four Continents, where they finished in 3rd, and the 2008 World Championships in Gothenburg, Sweden, where they were 12th. At the 2009 Nationals, Navarro/Bommentre again finished 3rd, but were left off the Worlds team in favor of Tanith Belbin / Benjamin Agosto, who had missed U.S. Nationals due to injury. They did compete at the 2009 Four Continents, where they finished in sixth place.
