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.

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.

Dan Annino joined Peter Millman's staff as the program's volunteer assistant coach in June 2020. Annino came to Homewood after spending three seasons as an assistant coach at his alma mater, Amherst College.

At Amherst, Annino held the Mammoths to a three-year record of 36-9. Amherst posted a 15-4 mark and advanced to the third round of the NCAA Division III Tournament in his first season as an assistant coach (2018) before finishing the 2019 season with an 18-4 record and the program's first appearance in the national championship game. The Mammoths were 3-1 and ranked seventh in the nation when the 2020 season ended abruptly due to the COVID-19 pandemic.

Annino was the architect of a Mammoth defense that held the opposition to nine goals or less 20 times under his direction and reduced its goals against average by more than two goals per game from the season before he joined the staff. For his efforts during Amherst's 2019 run to the national title game, Annino was the recipient of the IMLCA's Mike Clear Sr. Award as the Division III Assistant Coach of the Year.

A four-year regular and three-year starter on defense during his career at Amherst, Annino earned New England Intercollegiate Lacrosse Association (NEILA) All-New England honors as a senior and totaled 76 ground balls and 31 caused turnovers during his career.

As a player, Annino helped lead an Amherst defense that posted a combined 10.34 goals against average during his career while the Mammoths rang up and impressive 52-23 record during that time. The team appeared in four consecutive NESCAC postseason tournaments and advanced to the championship contest in 2014 and 2015. The team also appeared in three straight NCAA Tournaments 2014-2016 and advanced to the national quarterfinals in each of his last two seasons.

Annino graduated from Amherst in 2016 with a degree in economics.  He joined the Mammoths’ coaching staff following a year as an investment banking analyst at a firm in New York.

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 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.
