Tripp Keister has served as the Associate Athletic Director at Wesley College since the 2005-06 year.  He is also the head coach of the Wolverines' baseball team, where he guided Wesley to the 2010 ECAC South Championship.

A graduate of McKean High School, Keister earned a Bachelor of Science Degree in Physical Education at the University of Delaware in 1992, where he also lettered as a star outfield on the school's baseball team. Ironically, he played at UD under legendary Coach Bob Hannah, a Wesley College graduate. The New York Mets subsequently drafted him in the 32nd round of the 1992 Major League Baseball Draft.

After playing four years of minor league baseball, he became an assistant baseball coach at the University of South Carolina from 1996-98. Delaware State University hired him as its head baseball coach in July 1998, and over the 1999 and 2000 seasons, Keister turned around a losing program and led the team to a 45-38 overall record that included two Mid-Eastern Athletic Conference North Division titles, including a 14-1 mark in 2000. Keister left DSU after the 2000 season to assume a scouting post with the San Diego Padres. With the Padres, he served as an amateur scout, and also scouted the Philadelphia Phillies, Pittsburgh Pirates, and the Baltimore Orioles. He continued in the scouting post until he was named associate athletic director of development at DSU.
