Gretchen Moser was named head coach of the Saints volleyball program prior to the 2018 season. During her tenure heading into the 2026 season, she has posted 94 victories and has already become the program's all-time winningest coach in eight years.

In her first season directing the Saints, Moser helped the Saints double their win total from the previous season. In 2022, she directed the Saints to their first winning campaign since the 2014 year and the 17 wins were the most since 1999. Moser coached the 2023 team to a 7-6 mark in the GLVC, the most conference wins since 2008. She helped the Saints win a share of the GLVC regular-season title in 2024 with an 11-2 league mark and a 17-11 slate overall. Moser was voted the GLVC coach of the Year in 2024. She oversaw a fourth consecutive winning season in 2025, the first time the program had achieved that milestone since 1994.
