Coach Byrnes grew up in West Islip, NY and attended West Islip High School. He helped the Lions win the Class A New York State championship in 2010 and the Suffolk County title in 2011. At Marquette, Byrnes was named second-team All-American as a long-stick midfielder in 2016. Among the other awards he received was the most outstanding player in the Big East Tournament, during which he and his teammates beat the No. 1 team in the nation, the University of Denver, for the title. He also was named Big East defensive player of the year. He finished his Marquette career with 218 ground balls and 102 caused turnovers in 61 games. Byrnes became the first alumnus in school history to suit up for an MLL game, which came just four days after his final game at Marquette, a 10-9 loss to North Carolina in the first round of the NCAA tournament. That NCAA appearance also was a program first. He currently resides in the Atlanta area and coaches at Centennial H.S. in Roswell and with Thunder LB3 Lacrosse. Accolades:
