Mason Petrin was named the second Head Coach in the history of Carroll's women's bowling program in September of 2024. Prior to that, he spent three seasons with the Pioneers in an assistant role. Petrin's first season as Head Coach was a banner year for the Pioneers, as he was named CCIW Coach of the Year after earning the number two seed in the 2025 CCIW Tournament, which is the highest finish in program history. He led the Pios to the second and final day of that Tournament for the first time in program history. Petrin has coached two All-Conference bowlers, including the 2025 CCIW Bowler of the Year (Ava Butt), and one CSC Academic All-District honoree. Petrin has four years of college coaching experience. He was an assistant at Robert Morris and Head Coach at UW-Oshkosh from 2015-16, before coaching Robert Morris' men to the runners-up at the Intercollegiate Team Championship (ITA). He then led the school's women's team to the ITC Championship in 2019. A native of West Bend, Wis., Petrin attended Robert Morris University in Chicago for four years. He currently resides in Wauwatosa, Wis. with his wife Emily, their one-year-old son, Otto, and two dogs, Debo and Toby.  

Courtney Ermisch made the transition to Assistant Women's Bowling Coach at Carroll University for the 2024-25 school year, after a four-year stint as the program's first-ever head coach. Prior to arriving at Carroll, Ermisch served as the assistant coach of the women’s bowling program at Judson University in Elgin, Ill., where she oversaw compiling statistics for the program, creating team strategies, and motivating student-athletes to help build confidence and learn from the weak areas of their game.    Ermisch had experience with athletic departments before her time at Judson, as she was an assistant to the athletic department at her Alma Mater Robert Morris University. Ermisch was in charge of day to day tasks within the office, including mail, email, credit card logs, and answering questions from student-athletes.   Ermish graduated Summa Cum Laude from Robert Morris University with a Bachelor of Applied Health from Robert Morris University in May of 2019. While attending Robert Morris, Ermisch was a standout collegiate bowler as well. Ermisch won two national titles (2016 and 2019) and was named MVP of the ITC all-tournament team.
