Peter Milliman was named the 23rd head coach in Johns Hopkins history on April 27, 2020 after serving as the Richard M. Moran Head Coach of Men’s Lacrosse at Cornell University.
Milliman took over as the head coach at Cornell in 2018 and amassed a record of 28-10, including an 8-4 mark in Ivy League play. The Big Red went 13-5 in 2018, 10-5 in 2019 and were 5-0 and ranked second in the nation when the 2020 season ended.
Cornell advanced to the NCAA Quarterfinals in Milliman’s first season, when the Big Red also claimed the Ivy League Tournament title In two-and-a-half seasons, Milliman’s team beat the top-ranked team in the nation twice and picked up three victories against teams ranked in the top two in the nation at the time of the game; included was a win against top-ranked and eventual national champion Yale in the 2018 Ivy League Championship game.
Milliman arrived at Cornell in 2014 as an assistant coach and promptly helped the Big Red to back-to-back trips to the NCAA Tournament and a combined record of 21-11. Cornell went 9-3 in Ivy League play in 2014 and 2015 and tied for first place in the final regular season standings in each of those two seasons.
Milliman served as Cornell’s defensive coordinator early in his tenure, but seamlessly transitioned to the offensive side and quickly turned the Big Red into one of the most dangerous teams in the nation. Cornell finished fifth in the nation in scoring offense in 2019 (14.3) and the Big Red were averaging 18.4 goals per game when the 2020 season ended.
Before landing at Cornell, Milliman had successful assistant coaching stops at RIT (2006, 2008), Siena (2007), and Princeton (2013). In his four seasons at those schools he helped his teams to a combined record of 45-22 with a 9-6 mark at Princeton in 2013 immediately preceding his time at Cornell.
Milliman had his first head coaching stint from 2009-12 at Division II Pfeiffer. There, he led the Falcons to a pair of appearances in the Conference Carolinas title game in 2011 and 2012 and was twice named the conference coach of the year (2009, 2011).
Milliman was a three-time All-American at Gettysburg and helped the Bullets to back-to-back appearances in the NCAA Division III Championship game during his career (2001, 2002). He finished his career at Gettysburg ranked second in school history in points (232), fifth in goals (138) and third in assists. He remains one of just three players in Bullet history with more than 125 goals and 90 assists.

John Crawley, a four-year standout for the Johns Hopkins men's lacrosse team from 2014-17 and most recently an assistant coach at Lehigh, was appointed the Blue Jays' offensive coordinator on June 2, 2022.
Crawley's return to Homewood came after spending the previous three years as an assistant coach at Lehigh University. At Lehigh, Crawley served as the offensive coordinator of a Mountain Hawk offense that ranked among the nation's best throughout his tenure. Lehigh ranked 15th in the nation in scoring offense during the COVID-shortened 2020 season (14.00) and jumped into the top 10 in 2021 (14.08), when Mountain Hawks advanced to the NCAA Tournament for the first time since 2013.

A two-time captain and two-time Honorable Mention USILA All-American, Crawley played in all 64 games during his four-year career at Johns Hopkins and started the final 30 as a junior and senior. He totaled 70 career goals and 30 assists, including career highs of 21 goals and 11 assists for 32 points as a sophomore in 2015, when he helped lead the Blue Jays to the NCAA Semifinals and the inaugural Big Ten Tournament title.

He served as the Director of Operations at walax.com, a web site dedicated to all things related to lacrosse in the northwest. Walax was also heavily involved in the organization of lacrosse leagues, tournaments and clinics as the sport grew rapidly in the state of Washington. In addition, Koesterer coached the Seattle Starz, who won the 2010 Adrenaline High School Shootout.
Former Blue Jay All-American midfielder Brian Kelly joined head coach Peter Milliman's staff on June 28, 2022 as the program's volunteer assistant coach. Kelly, replaced Dan Annino, who had served in the role for two seasons before being named the head coach at Bates.
At the conclustion of the 2022 season, Kelly stepped down as the head coach at nearby Goucher after 10 seasons. Under his direction, the Gophers made three appearances in the Landmark Conference Tournament (2013, 2014, 2018), including one trip to the title game (2014).

Starting as a visiting team liaison in 2007, he later served as the head equipment manager (2008-10), assistant general manager/assistant coach (2011-18) and director of player personnel (2018) before making the move to general manager prior to the 2019 season.
