Debs Brereton has been an assistant coach on the ETSU women's soccer coaching staff for two full seasons after being introduced on June 2, 2011. 

In two seasons, Brereton has helped the Lady Bucs combine for a 24-11-1 record, including consecutive postseason berths. This past year, Brereton helped coach the Lady Bucs to their second consecutive 12-win campaign, tying the program mark once more for wins in a season.

In her first season at ETSU alongside head coach Adam Sayers, the Lady Bucs posted a 12-5-1 overall record as well as a 7-1-1 mark in Atlantic Sun matches. The 12 overall wins and seven conference wins both tied the program record for wins in a season, while the team netted a program best 43 goals en route to its first ever regular season championship.

Brereton comes to ETSU after spending the last three seasons as a graduate assistant on the women's soccer staff at Middle Tennessee State University. She was involved in various aspects of the program including player development and on-field training.

While working on the Blue Raider staff, Brereton helped guide the 2010 team to the program's first ever Sun Belt Tournament Championship and NCAA Tournament appearance. The Blue Raiders completed their championship season with an overall record of 13-9-2 while finishing second in the conference standings with a 9-2-0 mark.  

Brereton was also a player/coach for the Fort Wayne FC, located in Fort Wayne, IN. She participated in the Midwest-South division of the WPSL in 2010 and helped Fort Wayne advance to the playoffs for the first time in club history. Through eight games, Brereton managed to net four goals and tally three assists, as well as make a WPSL team of the week in June of 2010.  

Prior to accepting the GA position at MTSU, Brereton served as an assistant soccer coach at Christian Brothers University in Memphis, Tenn., for the 2007 campaign.

Brereton played three seasons in the W-League and the WPSL prior to starting her coaching career. She led the San Diego Sunwaves to the W-League Western Conference Championship in 2007 with an 8-3-1 record. While in the WPSL, Brereton led the Tennessee Lady Blues with seven goals in six matches in 2006, helping them finish second in the Midwest Division. In 2005, she scored three goals in two games for the W-League's Hampton Roads Piranhas before suffering a season-ending injury. 

Brereton’s collegiate career saw her play just one season for MTSU, in 2004, after transferring from Northeastern State; however, that one season proved to be one of the greatest in program history. She became the program's first Sun Belt Player of the Year after setting what was then the school record for goals in a season with 19. She also set the then-single-season points record with 47 and tallied nine assists to rank fourth on the single-season chart. Though she played for just one season at MTSU, Brereton is still among the career leaders in points and goals, ranking ninth in each category. 

In 2004, she not only was named the Sun Belt Player of the Year, but she also earned First-Team All-Sun Belt accolades and was named to the All-Sun Belt Tournament Team. Brereton was a three-time Sun Belt Player of the Week in 2004 - the most ever by a Blue Raider player in a season.

Her strong play also helped lead MTSU to a share of the 2004 Sun Belt regular-season championship, its first conference title. She was later named to the Sun Belt's 30-year Anniversary Team and earned a spot on the Soccer Buzz All-Central Region Team. 

A native of Middlesbrough, England, Brereton owns a FA Level Two Coaching License, NSCAA Level 1 & II Goalkeeper diplomas, as well as a USSF National "B" License. Since 2011, Brereton has been a head coach for the Tennessee State Olympic Developmental Program (ODP).

Brereton completed her eligibility at MTSU in 2004, earning her B.S. in physical education in 2005. In the spring of 2011, she earned a Master of Science in Health and Human Performance with a concentration in Recreation from MTSU.
