In September 2009, Bill Dunn was promoted to head coach of the NYIT lacrosse program, replacing now Head Coach Emeritus Jack Kaley. With this full-time role, he also became the strength and conditioning coach for NYIT Athletics. Dunn came to NYIT in 1999, serving as an assistant and defensive coordinator for a lacrosse team that won three national championships in his tenure.
Since 2010, Dunn has posted an overall record of 81-27 for a .750 winning percentage. Currently he stands at 48-12 in East Coast Conference regular season.
In 2016, Dunn and his staff directed the Bears to a 13-5 season, with a 7-1 mark in ECC play to earn the regular season ECC co-champion title. The Bears were defeated by a narrow 12-11 loss to LIU Post in the ECC finals, but still earned the No. 4 seed in the NCAA Tournament after a two-year hiatus with an at-large bid. NYIT scored five goals in the third quarter of the first round of NCAA play, but dropped an 8-7 overtime decision to eventual National Champions Le Moyne College. Nine players earned ECC accolades, including goalkeeper and defensive player of the year. Additionally, Dunn racked up his highest number (to-date) of USILA All-Americans with six, and Jon Lynott was named Most Outstanding Defenseman. Lynott and Nick Sidaras were chosen for the North/South All-Star game and subsequently chosen as USILA Scholar All-Americans for their efforts in the classroom.
The 2014 and 2015 campaigns under Dunn nearly mirrored each other, as the Bears finished 12-4 overall and 7-1 in the ECC, earning the second seed in the conference tournament. In 2015, NYIT advanced to the ECC Championship final after defeating Mercy 13-7 in the semifinals. Four players received USILA honors, headlined by three-time recipient Luke Miller. The four-time ECC All-Conference pick also earned his fourth consecutive major conference award as he was named Co-Offensive Player of the Year-Along with the 2014 USILA Division II Player and Attackman of the Year awards. Nine Bears received All-ECC honors.
Finishing at 12-3 overall and 6-1 in the ECC in 2013, No. 4 NYIT returned to the NCAA Tournament, drawing a first round game against local rival Adelphi. Despite scoring five goals in the last quarter, the Bears fell 14-11 to conclude their season. Danny McDermott and Luke Miller earned second and first First Team All-American accolades, respectively. Ryan Brunet was awarded Second Team All-American inclusion as well.
The Bears made a strong run for a bid to the NCAA Tournament in 2012 but fell short with a 13-3 overall record and an 8-2 East Coast Conference mark that was good for third place. NYIT had a total of eight Bears earn All-ECC honors including ECC Goalkeeper of the Year Billy McGee and ECC Rookie of the Year Luke Miller. Adding to NYIT's long tradition of All-Americans were McGee, Jason Smith and Danny McDermott, who earned first team honors, and Justin Annunziato, who was named honorable mention All-America. The awards did not stop there as Smith was named a COSIDA Academic At-Large All-District I first team pick.
In 2011, Dunn directed NYIT to a 10-4 record and a 7-3 ECC mark. The season was highlighted by a 10-7 upset of then-No. 3 Dowling. Again, NYIT had an opportunity to return to the NCAA Tournament but with a late season 10-8 edging at No. 3 Mercyhurst, the Bears' chance was lost. Six Bears received All- ECC accolades, while four were named USILA All-America — Ryan Amengual, Joe Herman, Chris Lubin, and Brian Mangan.
NYIT produced a solid 9-4 overall record and 6-3 ECC mark in Coach Dunn's first season. Six were named All-ECC, while four were named USILA All-America. Matt Sullivan was the lone first team selection, while Austin Carino, Pete Raab, and Kevin Hennessy were second team honorees.
Overall, Dunn has produced 29 USILA/Nike All Americans, one national Player of the Year (Luke Miller ’14), one Attackman of the Year (Luke Miller ’14), one Long Pole Midfielder of the Year (Danny Mcdermott ’14), and one Defenseman of the Year (Jon Lynott '16). He has been named ECC Coach of the Year twice and produced 53 Bears have garnered All-ECC honors under Dunn’s tutelage. Additionally, he has coached four goalkeeper and four defensive players of the year, three players of the year and two rookies all for the East Coast Conference.
Prior to his time at the helm, the Bears compiled a 114-21 record, advanced to the NCAA Division II tournament five times, and won the national title three times: in 2003, 2005, and 2008. Dunn was named the Intercollegiate Men’s Lacrosse Coaches Association (IMLCA) Division II Outstanding Assistant Coach of the Year in 2007.
A native of Hicksville, N.Y., Dunn graduated from Hicksville High School and played for SUNY-Cortland from 1977 to 1980. A defenseman, Dunn helped Cortland to three straight SUNYAC Championships and three trips to the NCAA Division II tournament, including one appearance in the national championship. Upon graduating, Dunn taught physical education and coached lacrosse and football at MacArthur, Hicksville, Kellenberg Memorial, and Long Beach high schools.
At Kellenberg, where Dunn founded the lacrosse program, he was named the Catholic High School Athletic Association (CHSAA) Coach of the Year and the Man of the Year twice. He led teams to the CHSAA finals three times. Dunn also has coached and played for the North Hempstead Lacrosse Club and served as defensive coordinator for the Empire State Games Team Long Island three times.
