Since ageing out of juniors, Persinger has medalled at every Women's National Championship she has competed in, six in a row as of 2020. At her first Women's Nationals in 2015 she played lead for skip Aileen Sormunen, they were the number one seed in the page playoffs but lost to Erika Brown in the 1 vs 2 game and to Patti Lank in the semifinals to finish with the bronze medal. In spite of their third place finish, Team Sormunen still earned the opportunity to represent the United States at the 2015 World Women's Championship because, of the top three teams at Nationals, they earned the most Order of Merit points throughout the season. They finished in tenth place with a 3–8 record.
