Career
Through 2001
Stellato began learning to skate as a five-year-old. In the 1999–2000 season, she won the ISU Junior Grand Prix Final and went on to win the silver medal at the 2000 World Junior Championships. A member of Wagon Wheel FSC, she was coached by Cindy Watson-Caprel and Philip Mills in Northbrook and Buffalo Grove, Illinois. Stellato began the following season at a U.S.-only team event, the 2000 Keri Lotion Classic, where she was partnered with Michael Weiss. She received a 6.0 for presentation. Making her senior international debut, she won silver at the 2000 Karl Schäfer Memorial in October. In November, she finished fifth at a Grand Prix event, the 2000 Skate Canada International, where she injured her right hip before the free skate. After returning to training two weeks later, Stellato sustained a pulled hip flexor in the same hip, which led to her withdrawal from the 2001 U.S. Championships. She later decided to retire from competition. Due to four different hip injuries, she had skated for an approximate total of 24 months in four years. Other injuries in her career included a torn ligament in her right ankle and a fractured left ankle.
Return to skating
Stellato resumed skating in March 2016, in the Chicago area, before visiting her former coach, Cindy Watson-Caprel, who had moved to a rink in Ellenton, Florida. In Florida, U.S. Figure Skating's high performance director, Mitch Moyer, suggested a tryout with Nathan Bartholomay, a pair skater who was working at the same rink. In July 2016, Stellato and Bartholomay announced that they had formed a partnership and were based at the Ellenton Ice and Sports Complex. Coached by Jim Peterson, they train on ice three hours a day, five days a week. Making their international debut together, the pair placed 6th at the 2016 CS Golden Spin of Zagreb. After taking the gold medal at the Eastern Sectional Championships, they qualified for the 2017 U.S. Championships where they finished in fourth place. The following year, Stellato-Dudek and Bartholomay placed third at the 2018 U.S. Championships. They placed fifth at the 2018 Four Continents Championships. Stellato-Dudek/Bartholomay opened the 2018–19 figure skating season with two Challenger events, winning silver at the Nepela Trophy and bronze at Nebelhorn Trophy. They placed sixth at the 2018 Grand Prix of Helsinki, and had to withdraw from the 2018 Rostelecom Cup. Competing a third Challenger event, they won another bronze medal at the 2018 CS Golden Spin of Zagreb. Stellato-Dudek/Bartholomay won a second consecutive bronze medal at the 2019 U.S. Championships. However, due to perceived inconsistent results earlier in the season, they were not assigned to the third American berth at the 2019 Four Continents Championships, that going instead to pewter medalists Tarah Kayne / Danny O'Shea. They announced the end of their partnership in April 2019. In August 2019, Stellato appeared on an entry list for Souvenir Georges-Éthier in partnership with Canada's Maxime Deschamps.
