Stagniūnas began skating at age five.[1][2] He moved to the United States at age 15 to skate with a partner.[2]
Early in his career, Stagniūnas was coached by Walter Wielunski and Natalia Dubova, who trained him in ice dancing. They trained in Darien, Illinois, where he lived with his partner, Laura Whipple. He and Whipple won the senior bronze medal at the Lake Placid ice dancing competition, representing Lithuania. In the 2003–2004 season, Stagniūnas began skating with Kayla Nicole Frey. They competed internationally on the junior level and were three-time (2004–2006) Lithuanian silver medalists.[3]
Partnership with Copely
In 2006, Stagniūnas formed a partnership with American Katherine Copely. They became the 2007 Lithuanian national champions and 2006 and 2007 Golden Spin of Zagreb bronze medalists. The duo qualified an entry for the 2010 Winter Olympics in the ice dancing event when they placed 14th at the 2009 World Championships.[4] According to IOC rules, competitors must have citizenship of the country they are representing; however, Copely's special request for citizenship was denied by Lithuanian President Dalia Grybauskaitė.[5] The spot was left unfilled. Copely retired from competition due to an injury which was subsequently treated arthroscopically, followed by a complete recovery. She is currently attending medical school in the U.S.[1]
Tobias/Stagniūnas won bronze at a Grand Prix event, the 2011 Skate America. In June 2012, they moved from Canton, Michigan to Novi, Michigan, following coach Igor Shpilband.[7] According to IOC rules, Olympic competitors must be citizens of the country they are representing. In order to allow the team to compete at the 2014 Winter Olympics, Tobias submitted an application for Lithuanian citizenship in October 2012.[8] It was denied on 7 January 2013.[9][10]
