St. Thomas played their first varsity game during the 1998–99 season. In the last 20 years, the Tommies have never had a losing season. They finished third or better in the MIAC every year. In the program’s 23-year history at the NCAA Division III level, the Tommies have won six conference championships, six conference tournament titles and reached the NCAA Division III frozen four once. The women’s ice hockey program was given the green light to jump directly to the Division I level in July 2020.
