Geldart comes to the Enchanted Valley after spending the past two seasons as an assistant coach for the men's lacrosse program at Berry College in Mount Berry, Georgia.

Geldart helped Berry College to 12 victories and to two appearances in the Southern Athletic Association Championships over the past two seasons. Geldart coached five All-SAA offensive performers during that time.

Prior to Berry, Geldart served three seasons as the assistant men's lacrosse coach at Oberlin College. He served as the team's offensive coordinator in 2020 after serving as the defensive coordinator the prior two seasons.

Geldart's offense was off to a solid start for the Yeomen through four games as Oberlin ranked third in the conference in both goals per game (13.25) and assists (33) while scoring on man-up opportunities at a 43.8 percent clip (7-for-16) before the remainder of the spring season was canceled.

In 2019, the Yeomen picked up 531 ground balls and held opponents to a .321 shot percentage. Under his guidance, goalie Calvin Filson made a career-best 157 saves and turned away 51 percent of the shots he faced.

In 2018, Oberlin drastically improved its goals against total going from 219 in 2017 to 149. Filson made 133 saves and turned away over 50 percent of the shots he faced. The Yeomen's backline scooped up a large portion of the team's 502 ground balls while also causing 123 turnovers.

Geldart moved to Oberlin College after coaching two seasons at Catholic University of America where he coached the defensive side of the ball. During his tenure, the Cardinals made it to two consecutive Landmark Conference Championships winning in 2016 and losing in 2017. The Cardinal defense only allowed 7.92 goals per game in 2017 after improving from 9.62 goals-allowed average in 2016.

Throughout college, he coached at Camp Greylock in 2013 and for the Old Line State Lacrosse Club in the summers of 2011 and 2012.

Geldart is a graduate of Frostburg State University, where he was a four-year member of the men's lacrosse team.
