Justin Kieffer, who joined the program in 2012, has been a part of all day-to-day lacrosse operations, with duties that include opponent scouting reports, recruiting, travel logistics, team meals, fundraising, social media, practice construction, and film exchange and breakdown. On the field, Kieffer primarily works with the offensive personnel players, goalies, and face-off players.
The Dutchmen appeared in the MAC Commonwealth Championship Tournament in 2021 after playing a shortened 2020 season due to the COVID pandemic. Kieffer assisted with coaching three 2021 All-MAC honorable mention honorees including defender Luke Tamberino, goalie Nick Serrano, and midfielder Alex Kiviniemi.
In 2019, Kieffer coached a strong group of MAC All-Conference selections: Kevin Beaver (1T Midfield), Cam Epple (2T Goalie), Matt Torrence (2T Midfield), Luke Tamberino (2T Defense), and Nick Mowry (HM Long-Stick Midfielder). He also worked with Beaver who became the third player in the modern era with 100 career goals at LVC. Beaver capped off his career by earning the MAC Scholar-Athlete of the Year award for men’s lacrosse. Beaver and Epple both earned a spot on the MAC Academic All-Conference team.
During the 2018 campaign, Kieffer helped to lead the Dutchmen to the MAC Commonwealth Championship Tournament for the fourth consecutive season. Five players in Coleman Wagner (1T), Kevin Beaver (2T), Blake Weaver (2T), Cam Epple (2T), and Nick Mowry (2T) picked up all-conference recognition. Wagner and Beaver were recognized with Academic All-MAC accolades for their success in the classroom, while Wagner also became just the second player in program history to earn IMLCA All-Region honors (HM).
In the spring of 2017, LVC returned to the MAC Commonwealth Tournament after Austin Minnich (1T), Klayton Garman (2T), Wagner (2T), Epple (2T), and Barrett Campbell (HM) turned in all-conference seasons. Minnich was especially strong in earning IMLCA All-Region recognition for the second year in a row to go along with a spot in the USILA North/South All-Star Game. The senior also became LVC's first player to be named a USILA/Nike Scholar All-American. Garman was named the USILA National Player of the Week after setting a program record by scoring nine goals in a game and he joined Minnich as Academic All-MAC honorees.
In 2016, he helped the Dutchmen to another appearance in the MAC Commonwealth Championship Tournament before earning a berth in the ECAC Tourney. Five players in Koty Keefer (1T), Minnich (1T), Wagner (2T), Epple (2T), and Mowry (HM) picked up all-conference recognition, while Minnich was named IMLCA Second-Team All-Region for the first time in his career. Keefer and Minnich also excelled in the classroom and were pegged Academic All-MAC.
In 2015, he helped coach the MAC Commonwealth Rookie of the Year and second-team all-conference midfielder in Keefer, and MAC Commonwealth Honorable Mention attackman in Garman. He oversaw one MAC Commonwealth Player of the Week, two ECAC Players of the Week, and a pair of USILA Players of the Week. The Dutchmen reached the quarterfinals of the MAC Commonwealth and ECAC championship tournaments.
In 2014, Kieffer helped coach the program's first-ever USILA All-American and ECAC All-Star in long pole midfielder Ryan Lanigan. During the season, he was a part of a staff that produced three MAC Commonwealth First-Team selections (Malik Pedroso, Ryan Lanigan, and Andrew Kruter) and an all-conference honorable mention (Scott Travers). Malik Pedroso was twice named the MAC Commonwealth Player of the Week during the spring. The Dutchmen ended their season in the ECAC quarterfinals.
The 2013 season was the most successful campaign of LVC's modern era. The team finished with a program-record 12 wins and reached the MAC Commonwealth and ECAC semifinal rounds. Kieffer helped guide five All-MAC Commonwealth selections during this season in first-teamers Ryan Lanigan and Malik Pedroso, second-teamers Andrew Kruter and Mike Moll, and honorable mention selection Ian Schmid. Three Dutchmen were named MAC Commonwealth Players of the Week that spring.
The 2012 season was Kieffer's first with the Dutchmen. LVC finished 9-6 and reached the MAC Commonwealth semifinals for the first time in the program's modern era. Kieffer helped coach three First-Team All-MAC Commonwealth selections in Pedroso, Kruter, and Scott Sutton. That spring, the Dutchmen garnered three MAC Commonwealth Player of the Week awards between Pedroso and Moll.
