Greg Barthel started his volleyball career at King's University College as a player, then Assistant Coach and finally Head Coach from 1999-2007. Since King's only entered their volleyball teams in the ACAC in 1997, Greg was responsible for building his teams into powerhouse contenders, leading his team to King's first ACAC medal. Before completing his time at King's, Greg went on to lead his team to a second bronze medal within a period of three years (2002-2005). In the 2003-04 season, Greg was named both the ACAC Men's Volleyball Coach of the Year as well as the CCAA Men's Volleyball Coach of the Year.
During his career at King's, Greg coached numerous players that went on to excel in CIS and internationally. He is currently the Head Coach of the Men's Volleyball program at the University of Regina and has been there since 2007.
