Mrozinski, who will work with the team's cornerbacks, served as head coach at Hiram College in Ohio for five years from 2020-24 and was the defensive coordinator at Salve Regina University in Rhode Island for three seasons from 2017-19. At Salve he helped lead the Seahawks to a 17-13 (11-7 conference) record and a Commonwealth Coast Conference (CCC) Co-Championship, as well as a New England Bowl berth in 2018. His defensive units finished first in the league in scoring defense in 2017 and second in 2018 and 2019.

Prior to joining Salve Regina, Mrozinski spent six seasons as an assistant coach at Ithaca College. He started with the Bombers in 2011 as the special teams coordinator, defensive backs coach and recruiting coordinator, adding video coordinator duties as well during his final four years. Mrozinski helped the Bombers to back-to-back Empire 8 championships and NCAA Division III playoff berths in 2013 and 2014.

He received the Coaches Award, given to the player(s) who "exemplify and demonstrate special character," in 2006 and the Al Abgott Attitude Award, given to an "unselfish, unsung player who never misses a responsibility to the team and is always pushing players around him to be better" in 2004 and 2005. Mrozinski earned his bachelor's degree in communications from Buffalo State in May 2006 and his master's degree in communications from Ithaca in August 2015.
