Cournoyer guided the Norwich University men's and women's swimming & diving programs through one of the most successful eras in school history. Her final campaign came during the 2025-26 season, when the Cadets completed another sweep of the Great Northeast Athletic Conference (GNAC) Championships and captured both the men's and women's team titles for the fourth consecutive year. The performance capped a remarkable run that saw Norwich become the standard in the conference, rewrite record books across both programs, and develop a long list of championship performers and major award winners.
Over her tenure, Cournoyer helped lead Norwich to nine GNAC team championships between the two programs, including eight combined titles over her final four seasons. The Norwich men claimed GNAC crowns in 2020, 2023, 2024, 2025, and 2026, while the women captured four straight titles from 2023 through 2026, completing the program's first championship four-peat since the turn of the century.
Before arriving at Norwich, Cournoyer built a long and accomplished coaching résumé across collegiate swimming & diving. She spent 16 seasons at the University of Vermont, serving as associate head coach from 2010 to 2019 after previously working as an assistant and volunteer coach. She also served as head coach at Lock Haven University and King's College in Pennsylvania.
A former NCAA swimmer and team captain at Bloomsburg University, Cournoyer earned her bachelor's degree from Bloomsburg in 1995 and later completed her M.Ed. at the University of Vermont in 2019. In addition to her coaching role at Norwich, she has remained active in the aquatic community as the Aquatics Director for Goodyear Pool, and also served as the department's Senior Woman Administrator during the 2025-26 season.
