Aquinas College Men's Lacrosse

Peter Treppa was named the Aquinas men's lacrosse head coach in the summer of 2024. Treppa took over for Chris Klaiber following three successful seasons. He is now the fourth official head coach in the history of the Aquinas men's lacrosse program.  Treppa primarily served as an assistant coach and defensive coordinator for the Saints over the past six seasons. He was the top assistant on the coaching staff and was the interim head coach during the 2021 campaign. Excluding the canceled 2020 season, coach Treppa helped coach Aquinas to national appearances in two of the last five seasons. AQ made a run to the national championship game in 2019, finishing as the national runner-up. Once again, Aquinas made it to the national tournament in 2022 before falling in the semifinals. The Grand Valley State University alumni boasts a career record of 48-25 since 2019. The AQ men's lacrosse program has had a prolonged run of success, being nationally ranked every year since Treppa joined the program. Individually, men's lacrosse athletes have garnered a significant number of accolades since Treppa joined the sidelines. AQ had boasted 18 First Team All-Conference players, 12 Second Team All-Conference athletes, the 2019 WHAC Offensive Player of the Year, and two WHAC Newcomers of the Year. Aquinas has also had a healthy amount of national recognition with nine All-Americans over the past six years. In addition to being the AQ Defensive Coordinator, Treppa has coached for the Premier Lacrosse Group (PLG) since 2022. He coaches youth and high school travel teams for the club. Prior to his time at Aquinas, Treppa served in a similar role at GVSU, working under head coach Tim Murray as an assistant coach and defensive coordinator for the Lakers from 2016 to 2018. Not only has Treppa experienced a healthy amount of success as a coach, but his success started as a player. He played 12 games as a freshman for the Adrian Bulldogs, helping the team to a MIAA conference championship and finishing the season as an NCAA Quarterfinalist. He transferred to Grand Valley State University and went on a dominant run with the Lakers. He was named a three-time All-American and three-time All-Conference athlete for GVSU. Treppa helped GVSU to a national championship in 2014 and conference championships in both 2014 and 2015. He went on to be named the team captain in 2015 and 2016.  Peter gruadated from Grand Valley State University in 2016, majoring in history with a concentration in secondary education. When he is not on the sidelines coaching, Treppa enjoys traveling, playing hockey, and spending time with family. 

Matt Wagner rejoined the Saints as an assistant coach after a decorated Aquinas playing career (’22). A shutdown defenseman, he was a 4× WHAC First-Team selection and 3× NAIA All-American, bringing elite standards and a defender’s mindset to the staff. Wagner arrives from Forest Hills Eastern, where he served as assistant varsity coach and head JV coach, helping the program to a 2024 state runner-up finish. He holds a bachelor’s degree in Business Administration with a dual major in Sports Management, and is based in Grand Rapids, Mich. Known for his energetic, detail-driven work with the defensive unit and man-down schemes, Wagner is passionate about player development and program culture. Away from the field, he enjoys college and pro football, bowling, golf, and—of course—lacrosse. The son of Todd and Jodie Wagner, he has one sister, Jordan. Wagner chose Aquinas to give back to “an amazing program” and help the Saints compete at the highest level.
