Rewkowski has made an immediate impact as the Blue Hens offensive coordinator.

In 2019, Rewkowski mentored both junior Charlie Kitchen and freshman Tye Kurtz, the CAA Offensive Player of the Year and the CAA Rookie of the Year, respectively. Kitchen marked the first OPOY since Curtis Dickson in 2010, while Kurtz became the first ROY since Alex Smith in 2004. Kurtz also joined rookie Clay Miller on the College Crosse Freshman All-America team, while Dean DiSimone garnered first team All-CAA honors.

As an offensive unit, the Blue Hens ranked second in the conference a year ago, putting 10.57 shots in the back of the net per game. Charlie Kitchen, Dean DiSimone and Will Hirschman nabbed All-CAA honors under Rewkowski’s tutelage.

Rewkowski spent the previous five seasons assisting at Georgetown where he served under former UD assistant coach Kevin Warne, following a two-year tenure on DeLuca's staff as associate head coach at Cornell.

“Matt has extensive experience and success playing and coaching lacrosse at the highest levels," DeLuca said. "He is a gifted teacher with a strong work ethic and knows what it takes for our program to be successful on the field, in the classroom, and in the community. Most importantly to me, I believe Matt is a man of high character and outstanding values.

Rewkowski is a 12-year veteran of the coaching ranks following an outstanding playing career at Johns Hopkins and Duke and a pro career with the Denver Outlaws of Major League Lacrosse. He was a senior co-captain for the Johns Hopkins team that captured the 2005 NCAA title and earned his degree there that same spring.

A native of Bethpage, New York, he began his coaching career at the University of Denver in 2006 before moving on to Delaware's CAA rival Hofstra where he served four seasons (2007-10) and led the Pride to 36 victories, two CAA titles, and three NCAA Tournament berths. He coached eight All-Americans and 27 All-CAA selections during his tenure and the 2010 team ranked No. 5 nationally in scoring (12.93 gpg).

Rewkowski moved on to Cornell and served for two seasons as DeLuca's associate head coach in 2011-12. He helped lead the Big Red to an NCAA Tournament quarterfinal berth in 2011 when the team won the Ivy League title, went 14-3 overall, and ranked No. 2 nationally in scoring at 12.7 goals per game.
