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 15^th 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.
 
Overall, during Crawley's 33 games as Lehigh's offensive coordinator, the Mountain Hawks averaged just under 13 goals per game and the three single-season season scoring averages of 14.08, 14.00 and 11.40 rank as the three highest averages at Lehigh in the last 20 years.  Prior to Crawley's arrival, Lehigh had not averaged more than 11 goals per game over the course of a season since 2000.
 
Crawley began his coaching career at Notre Dame in 2018 and helped the Irish to the ACC Tournament title and a trip to the NCAA Tournament.  At Notre Dame, he worked closely with the offense and faceoff unit.  He then moved to Colgate for one season (2019) before joining the staff at Lehigh.
 
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 earned a spot on the 2015 NCAA All-Tournament team after a four-goal performance against Maryland in the NCAA Semifinals.
 
In addition to his time at Johns Hopkins, Crawley has also played professional lacrosse in both Major League Lacrosse and the Premier Lacrosse League.  He was selected 33rd overall by the Charlotte Hounds in the 2017 MLL Draft and played two seasons for the Hounds.  He rang up 26 goals and 10 assists in the MLL before moving to Atlas LC in the PLL, where he has played three seasons and has 12 goals and six assists to his credit.

Jamison Koesterer was appointed the Blue Jay defensive coordinator on May 8, 2020 after serving four years in the same role at nearby UMBC.  A 2007 Johns Hopkins graduate, this is Koesterer's second stint on the Blue Jay coaching staff as he had previously served at Homewood in 2011 and 2012.

Koesterer joined the UMBC coaching staff in July 2016 and quickly made an impact on the Retriever defense.  His unit finished in the top 20 in scoring defense in 2017 (19^th / 9.14), 2018 (1^st / 7.77) and 2020 (6^th / 8.40); the 7.77 goals allowed per game by the 2018 team is a UMBC single-season record.  The Retrievers also finished eighth in the nation in man-down defense in 2018 and were ranked second in 2020.

Prior to his time at UMBC, Koesterer spent four seasons at Ohio State and helped the Buckeyes to a pair of trips to the NCAA Quarterfinals (2013, 2015) while working with the defense and faceoff specialists.

While in Columbus, he coached the 2016 Big Ten Specialist of the Year in Jake Withers, while Withers (2014 – ECAC, 2016 Big Ten), Chris May (2015- Big Ten) and Trey Wilkes (2013 – ECAC) each earned all-league honors as faceoff specialists under Koesterer’s guidance.

In addition to his work with the Ohio State faceoff specialists, he also assisted with Buckeye defenses that ranked among the nation’s best in 2013 (13^th / 8.83), 2015 (17^th / 9.16) and 2016 (19^th / 9.07).

Koesterer served as the volunteer assistant coach at Johns Hopkins in 2011 and 2012 and helped the Blue Jays to a two-year record of 25-7 with two trips to the NCAA Quarterfinals.  He mentored senior Matt Dolente to First Team USILA All-America honors in 2011, when he finished second in the nation in faceoff winning percentage (.667); Dolente’s faceoff winning percentage that season ranked second in school history at the time.

A year later, Koesterer’s faceoff unit finished seventh in the nation (.578) with junior Mike Poppleton leading the way by winning 167-of-271 (.616).

Koesterer played at Johns Hopkins from 2004-07 and was a member of the Blue Jays’ national championship teams in 2005 and 2007.  He scored seven goals and added 12 assists and 101 ground balls during his career.  He also won 176-of-318 (.553) career faceoffs and helped guide the Blue Jays to a 51-11 record.

After graduating, Koesterer continued his playing career in the National Lacrosse League as a member of the Portland Lumberjax (2009) and the Washington Stealth (2010).  He helped the Stealth to the 2010 NLL Championship – the first title in franchise history – by winning 265-of-446 (.594) faceoffs while collecting 101 loose balls (the equivalent of a ground ball in indoor lacrosse).

In addition to his playing career professionally and at Johns Hopkins, Koesterer originally returned to Homewood for the 2011 season after working tirelessly in the state of Washington to grow the game at the youth level.  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).  He coached 22 all-conference selections, two USILA All-Americans and a pair of USILA Scholar All-Americans.
 
Prior to his 10-year stint as the head coach, Kelly had served for five seasons as an assistant at Goucher.  During that time, he helped the Gophers to a pair of trips to the NCAA Tournament (2010, 2012) with an appearance in the second round in 2012.  That year, the Gophers set school records for wins (18) and winning percentage (.900), won a school-best 15 consecutive games before falling to eventual national champion Salisbury in the NCAA Tournament and set more than a dozen single-season team and individual records.
 
During his career at Johns Hopkins, Kelly helped the Blue Jays to the NCAA Semifinals in 1992 and 1993 and garnered Honorable Mention USILA All-America honors as a midfielder in 1993.  He was awarded Johns Hopkins' George D. Penniman Award as the team's top midfielder and the Turnbull-Reynolds Trophy for Outstanding Sportsmanship and Leadership during his final season.

In his first year as the Director of Men's Lacrosse Operations is Jon Cohen.  Cohen joined Peter Milliman's staff in June 2020 and manages much of the day-to-day logistical operation of the program.

Cohen most recently served as the General Manager of Major League Lacrosse's Denver Outlaws.  The GM post was the latest in a long line of positions Cohen held with Outlaws during a 14-year run with the team.

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.

Cohen, the longest tenured member of the Outlaws' player/coach roster, helped Denver to 118-62 (.656) regular season record from 2007-20 with MLL Championships in 2014, 2016 and 2018.  The Outlaws also advanced to the MLL title game six other times and played in the title game every year from 2016-2020.  Denver's 14-0 record during the 2013 regular season marked the first time in MLL history a team had gone through the regular season unbeaten.

Cohen graduated from UNLV in 2009 with a degree in hospitality management.  As a defender, he was a three-year member of Runnin' Rebels' club lacrosse team.  He got his start in coaching while still a student at UNLV as he served as an assistant boy's lacrosse coach at Bishop Gorman High School in Las Vegas and helped the team to the 2009 Nevada State Championship and also served as the head coach at Heritage High School in Colorado after relocating to the Denver area following his graduation from UNLV.
