Gunter began her coaching career at Middle Tennessee State University where she led the Blue Raiders to undefeated seasons in both of her years there (1962–1964). Gunter then had a very successful coaching stint at Stephen F. Austin State University (SFA) in Nacogdoches, Texas. While at SFA, Gunter led the LadyJacks to a 266-87 mark in 16 years as head coach (1964–1980). In addition, she led SFA to four top 10 national rankings, including top 5 final rankings in 1979 and 1980. While at SFA, Gunter coached four sports—women's basketball, softball, tennis and track. Her basketball teams went to five Association of Intercollegiate Athletics for Women (AIAW) playoffs, won four state titles, and earned a regional crown. In 1980, she stepped down as coach at SFA and moved into the position of Director of Women's Athletics where she served two years before returning to the coaching ranks at LSU.
