University of the Pacific

In her first season at the helm of Pacific, Gunn earned her 100th career coaching victory following the team's win over Eastern Washington. Gunn also earned her first WCC victory with a dramatic comeback win over LMU on senior day.

After coaching Southeast Missouri State to five conference championships over her final four seasons with the Redhawks, Mary Beth Gunn was named Head Coach of the Pacific women's tennis program in June 2024.
 
Gunn, who spent nine seasons as the head coach at SEMO, guided the program to regular season titles in 2021, 2023 and 2024, and conference tournament championships in 2022 and 2023. The program made back-to-back NCAA Tournament appearances in 2022 and 2023 after earning automatic bids.
 
Gunn's success at SEMO was an historic turnaround. She inherited a program that was on a string of nine consecutive losing seasons before posting a 13-8 (5-4 OVC) mark in her second year in 2017. She continued to build it into a championship program as the Redhawks won their first-ever OVC title in 2021 with a program-best 7-0 mark in league play.
 
Gunn's teams went undefeated in the OVC three times in the last four seasons. It included records of 15-5 (7-0 OVC) in 2021, 17-3 (5-0 OVC) in 2023 and 12-7 (6-0 OVC) in 2024. The 17 wins in 2023 tied the most in program history, and the Redhawks won both the regular season and OVC tournament title in the same year for the first time ever.
 
SEMO entered the 2023 NCAA Tournament on a 16-match winning-streak, the longest in program history. The team earned five All-Conference selections, the most in program history.
 
Gunn was named the 2021 OVC Coach of the Year and mentored the 2021 Player of the Year Romana Tarajova, the first Player of the Year in program history.

During the 2020 season, Gunn led the Redhawks to their first OVC Championship win in 16 years as No. 5 SEMO knocked off No. 4 Belmont 4-1.
 
Prior to joining the Redhawks, Gunn was the head coach at Western Illinois and also served stints as the assistant coach at Limestone College (2014-15) and UT Martin (2009-13).
 
Gunn was on coaching staffs for two conference championship teams. She helped lead UT Martin to the OVC Women's Tennis Championship in 2011 and Limestone College to a Conference Carolinas women's tennis title in 2015. Gunn was named the Intercollegiate Tennis Association Assistant Coach of the Year in 2015.
 
Gunn earned both her bachelor's degree in English and History (2008) and master's degree in Education (2011) from UT Martin. She was a standout tennis player at UT Martin, earning All-OVC honors with the Skyhawks in 2007.
