She and Cohen were the 2007 U.S. novice silver medalists. She did not make it out of sectionals as a single skater. Yankowskas and Cohen were coached by Alexander Vlassov and Laura Amelina.
Partnership with Coughlin
In June 2007, Yankowskas had a tryout with new coach Dalilah Sappenfield in Colorado Springs, Colorado. Sappenfield suggested John Coughlin as a potential partner and they had a tryout in early August 2007. They placed 6th at the 2008 U.S. Championships and made their Grand Prix debut at the 2008 Skate America. During the 2010–11 season, their Ave Marialong program was a tribute to Coughlin's mother who died in February 2010. They finished 4th at 2010 NHK Trophy and won the first Grand Prix medal, bronze, at Cup of China. At the 2011 U.S. Nationals, they placed first in the short program and then won the free program to earn their first national title. Yankowskas and Coughlin went on to a sixth-place finish in their debut at the World Championships in April 2011; it was the best result by an American pair since 2006. After the event, Coughlin told Yankowskas that he wanted to split up. On May 4, the pair announced the end of their partnership.
Later partnerships
After leaving Sappenfield and Colorado Springs, Yankowskas moved in July 2011 to Canton, Michigan, to train with Johnny Johns and Adrienne Lenda at the Arctic Edge Ice Arena. She skated for seven weeks with Italian skater Matteo Guarise but the pairing did not go further because they were unable to agree on which country to represent. In December 2011, Yankowskas said that she still wanted to continue her pairs career. On March 22, 2012, it was announced that Yankowskas had teamed up with Joshua Reagan. They were coached by Johnny Johns, David Kirby, and Marina Zueva in Canton, Michigan. Yankowskas and Reagan were assigned to the 2012 Cup of China and the 2012 NHK Trophy but withdrew from both events after Reagan sustained a rib injury in practice. They parted ways at the end of the season. In May 2013, Yankowskas formed a partnership with Hamish Gaman, coached by Johnny Johns and Marina Zueva in Canton, Michigan. Competing for Great Britain, the pair placed fifth in their debut at the 2013 Ice Challenge. They went on to take the bronze medal at the 2014 British Championships. In mid-February 2014, they moved to Boston and began training under Bobby Martin and Carrie Wall at the Skating Club of Boston. After spending part of June 2014 in Montreal, coached by Bruno Marcotte and Richard Gauthier, the pair decided to move there in July. At the 2015 European Championships in Stockholm, Yankowskas/Gaman placed seventh in the short program, 14th in the free skate, and ninth overall. On September 10, 2015, Yankowskas and Gaman announced their retirements from competitive figure skating due to lack of funding.
