Since his hire, the Hawks have proven themselves to be one of the most consistent programs in the Northeast. Inheriting a program that posted a 2-11 record in 2015, Saint Anselm has since made four consecutive NE10 postseason appearances, starting with an 8-6 record in the 2016 season. Under his direction, the Hawks have become regulars in the United States Intercollegiate Lacrosse Association (USILA) Division II Coaches' Poll and began the 2018 season as the No. 13 team in the nation, its highest-ever rank to begin a season.

In the shortened 2020 season, Sciamanna and the Hawks finished with a 3-0 record, picking up two victories over nationally-regarded programs. Saint Anselm logged a season-opening win over No. 18-ranked New York Tech to crack the USILA national coaches' poll. After an overtime victory against Florida Tech next time out, the Hawks handed Georgian Court, a team receiving votes in the national poll, a convincing 15-6 defeat. The Hawks finished the season ranked as high as No. 18 in NCAA Division II and through three games posted the nation's best clearing percentage (0.938) and was one of only 11 teams in the division without a defeat.

In 2019, Saint Anselm finished the year ranked 20th in all of NCAA Division II in the final coaches' poll released by the USILA. The Hawks earned a spot in the Northeast-10 Conference postseason with a 6-5 mark against league opponents, the fourth consecutive postseason appearance for the Hawks under Sciamanna. The team played an arduous schedule, taking on seven opponents mentioned in the USILA Coaches' Poll in 2019. Five members of the Hawks roster earned All-Conference honors and as many student-athletes were selected to New England Intercollegiate Lacrosse Association All-New England Teams.

The 2018 campaign was a breakout one for men's lacrosse on the Hilltop as the Hawks, ranked 17th in NCAA Division II by the USILA at season's end, posted an 11-5 overall record. The 11 wins were the most in one year against Division II opponents and the Hawks also secured their first-ever win against the nation's top-ranked team, defeating Le Moyne in the NE10 Semifinals. The Hawks also posted the nation's 15th-best scoring offense (12.63) and scoring defense (8.38), ranking 18th overall in points per game (19.31). The squad set the program record in goals scored (202) and tallied 309 points (202-107=309) as a team, the second-most in a single season.
