Geary spent the last five seasons at Saint Louis, starting as an assistant coach in June 2013 following four seasons as an assistant at the University of Detroit Mercy. He was promoted to associate head coach in June 2014. During his tenure, he helped lift the SLU program to two WNIT appearances and captured an A-10 regular-season co-championship.
Geary helped Detroit Mercy post a 21-13 record and win the Women's Basketball Invitational in 2012-13. That followed a 2011-12 campaign that saw the Titans go 20-14 and earn a WNIT bid. Prior to that, Geary spent two seasons as an assistant coach at Ball State. He helped guide the 2006-07 Cardinals to a 24-7 ledger, the Mid-American Conference West Division title and a WNIT berth.
Geary had success as a head coach at the NCAA Division II level, leading Lake Superior State to the 1988 NCAA Tournament round of 16 in his second season, and the Lakers were 47-10 in his two seasons. He then took over a Northern Michigan program that was 9-18 the year before and produced a 24-4 slate in 1988-89. During his 17-year stint there, his teams compiled a 370-123 record and had 12 seasons with 20 or more victories. The Wildcats became the first NMU women's basketball team to play in the NCAA Tournament, the first of 11 national tournament appearances under Geary's direction. He was named Great Lakes Intercollegiate Athletic Conference (GLIAC) Coach of the Year.
"Coach Geary's head coaching experience will be vital to game preparation and in-game adjustments," La-Force said. "Overall, his coaching style adds another perspective on how to get the best out of our team both on and off the court. He has been a vital piece in assisting every program he has been affiliated with win championships. His familiarity with the A-10 will allow a smooth transition with scouting and preparation."
Geary's Northern Michigan teams captured seven GLIAC Tournament crowns, including four consecutive from 1995 to 1998, and played in seven NCAA regional championship games. His players earned five All-America awards and six GLIAC Most Valuable Player honors.
