After spending the 2011 season at the Senior Assistant Coach/Offensive Coordinator at Washington College, J.L. Reppert returned to his alma mater in 2012 to direct the Mids' offensive efforts. Reppert helped improve Navy's shooting percentage immensely, jumping from 28th (.280) to 13th (.311) over the course of a year. He also helped Tucker Hull hone his skills into an All-Patriot League attackman who stood 13th nationally a year ago in points per game (3.92) and 11th in assists per game (2.00).
Under his tutelage, last spring Tucker Hull and Sam Jones became only the fourth set of classmates in program history to reach 100 points, joining Brendan Schneck (121) and Mike Hannan (101) from the Class of `78, Mike Herger (197) and Brian Keith (134) from the Class of 1990 and Ian Dingman (188) and Billy Looney (103) from the Class of 2007. Hull is tied for 23rd on Navy's all-time scoring list with 106 points, while Jones is 26th with 102 points.
Reppert was a four-year starter at attack for the Navy lacrosse team from 1996-99, helping lead the Mids to an NCAA Tournament berth in 1999. He was bestowed one of the finest honors a Navy student-athlete can achieve, being voted by his peers to serve as team captain in his senior year. He was also the recipient of the Vice Adm. E.C. Waller Award presented to a Navy lacrosse player for spirit, morale and dedication to the program.
Reppert graduated from the Academy with honors in 1999, earning a bachelor of science degree in political science, and was commissioned a second lieutenant in the Marine Corps. He went on to graduate from the Naval Postgraduate School in Monterey, Calif., in 2004, earning his M.B.A in finance and was a Conrad Scholar. From 2000-03, Reppert was stationed at Marine Corps Air Station Miramar as a finance officer. He was promoted to Captain in 2004 and began working in the Programs and Resources Department at Headquarters Marine Corps as a Congressional Liaison. After serving nine years in the Marine Corps and achieving the rank of Captain, Reppert left the corps to begin his coaching career.
Along the way, Reppert has held high school assistant coaching jobs at St. Albans (D.C.), Episcopal (Va.), Gonzaga (D.C.), Robert Louis Stevenson (Calif.) and Poway (Calif.). He has also served as the manager of Champions Field House in Rockville, Md., and as founder and partner in Breakout Lacrosse Company, based in Washington, D.C.
Reppert, who resides in Alexandria, Va. with his wife, Jill, and son, Liam, earned his first college coaching job in 2009 at Harvard where he served under former Navy assistant coach and current Maryland head coach John Tillman. While at Harvard, his responsibilities included developing and maintaining the team's budget, serving as director of operations, managing Crimson Lacrosse Camps and assisting in the development of the team's offense.
