|Alma Mater:||Saint Michael's '15|
Alumnus Sean Curtin '15 returns to the Saint Michael's men's lacrosse program for his fourth season as an assistant coach in 2019.
The Purple Knights doubled their win total in 2018 while tying for seventh in NCAA Division II in man-down defense (80.0%). Saint Michael's posted its fewest turnovers in a decade, its lowest goals-against average (9.57) in five seasons, and the fourth-most caused turnovers (133) in program annals. The Purple and Gold reeled off three straight wins in mid-March, yielding only 13 goals in that stretch, when the Purple Knights posted three straight shutout periods for the first time since April 6, 2006. Their shutout streak reached 56:55 at one point, their longest since the 2004 season. During its home finale, Saint Michael's lost to the top-ranked team in the nation, Le Moyne College, by a slim 10-8 margin.
In 2017, Saint Michael's faced a seven-game, month-long stretch during which each opponent was either nationally ranked or receiving national votes, with six foes ranked. Despite fielding a roster that included 15 players in their initiail season of college lacrosse, four of those games ended in losses suffered by five goals or fewer, among seven such contests on the season. Following a 19-6 win over American International College, the Purple Knights closed the year with back-to-back one-goal setbacks.
The Purple Knights put together a 3-2 surge to end the 2016 season, Curtin's first as a college coach, one which saw the squad lose three times by a single goal. Saint Michael's was in the top third nationally in saves per game (11th), caused turnovers per game (12th) and man-down defense (18th), taking fourth in the North Region in the former two categories.
Curtin, who was a captain as a senior in 2015, graduated ninth in program history in career caused turnovers (32), as the long-stick defenseman also scooped 64 ground balls in 49 games. Curtin earned his degree in information systems.
