Tanith Belbin and Ben Agosto are the three-time and reigning national champions, as well as two-time world medalists and Olympic silver medalists. Belbin and Agosto train in Detroit under Igor Shpilband, who has been their coach since they became partners in 1998, and Marina Zueva.

Belbin and Agosto's success started early in their career, winning the US Junior dance title and winning the bronze at Junior Worlds in their first season competing together.  In the next seasons, they completed their set of Junior Worlds medals, by taking silver in 2001 and gold in 2002, and had a solid start to their senior career, winning two silver medals at Nationals, which also qualified them for the world team. Since then, they have only improved, picking up many more medals and accolades, including three Skate America titles, three Four Continents Championship titles, the USOC 'Team of the Month' award for both January and February of 2006, and the SKATING magazine's Readers' Choice Award. They are the 2006 Olympic silver medallists.

Belbin is originally from Canada and had to receive US citizenship to compete at the Olympics. Belbin and Agosto had previously qualified for the Olympics in 2002, but were unable to attend because Belbin lacked US Citizenship at that time. Belbin became a citizen in December 2005.
