Jen Mackson is beginning her ninth season as an assistant coach for the Lakers, primarily working with the team's pitchers. One of the top pitchers in GLIAC history, Mackson was a four-year letterwinner for Grand Valley State from 2001-04 and played under current head coach Doug Woods. As a coach with GVSU, the Lakers have tallied an overall record of 263-148 (.640) with a GLIAC tally of 117-73 (.616).
As a player, Mackson was a part of some of the best teams in Grand Valley State history. From 2001-04, the Lakers were 182-33-2 overall (.843) and 64-14 (.821) in conference play. GVSU won 48 games in 2001 and recorded 49 wins in both 2002 and 2003, tied for the second-highest win total in school history. In 2002, the Lakers won the Great Lakes Regional Championship and advanced to the NCAA National Championship game, its highest-ever finish.
A key member of those teams, Mackson was a three-time GLIAC Player of the Year from 2002-04. That is an unprecedented feat, as only one other player in conference history (Wayne State's Tish Miller in 1986-87) has even won two conference player of the year awards. Mackson is first in Laker history in wins (103), earned run average (0.67), innings pitched (821.0), complete games (102), shutouts (58), and strikeouts (1,015). Her overall record in the circle was an incredible 103-16, as she held opponents to a .155 batting average, the lowest figure in school history.
She also ranks first in GLIAC history in wins, ERA, innings pitched, and is second in strikeouts. In addition to her 103 victories, she is second all-time in conference history with 16 saves, meaning she had a hand in 119 of GVSU's 182 victories during her four seasons.
A four-time All-GLIAC honoree, Mackson was a three-time NFCA Great Lakes Region selection, a 2002 NFCA First Team All-American, a 2003 NFCA Second Team All-American, and a 2003 Academic All-American.
Mackson graduated from Grand Valley State in 2005 with a degree in elementary education. She currently works at William C. Abney Academy in Grand Rapids, where she also resides.
