Truman State Director of Athletics Jerry Wollmering introduced David Gannon as the new head volleyball coach at the University. Gannon becomes a Bulldog after serving as an assistant coach at Division I University of Idaho and Weber State University. Gannon becomes the 10th head coach in program history replacing Ben Briney, who served in that roll the past 12 seasons and compiled a record of 243-141. Briney resigned earlier this summer to take a job as Athletic Director and Head Volleyball Coach at Westminster Christian Academy in his hometown of St. Louis.
In March of 2015, Gannon was named Assistant Coach and Offensive Coordinator for Weber State University in Ogden, Utah. The Wildcats posted records of 18-10 and 26-9 in his final two seasons at Weber State and the program had nine players selected to the Big Sky All-Conference team during his tenure.
In March of 2019, Gannon shifted within the conference back to Idaho as the top Assistant Coach and Recruiting Coordinator. The Vandals had five all-conference players, three in the 2019 season and two in the abbreviated 2021 spring season.
Gannon started his collegiate coaching career while attending Arizona State University. Gannon was the assistant coach at Mesa (Ariz.) Community College and following graduation with a degree in Physical Education, moved on to the University of Idaho as Director of Volleyball Operations in 2014.
Gannon has also been a club coach that competed in the Junior Olympic qualifiers and worked as a coach for USA Volleyball High Performance.
