A native of Ballina, Ireland, O’Sullivan was hired at Clayton State in February of 2011 after most recently serving as the head coach of the Atlanta Beat of the WPS (Women’s Professional Soccer) in 2009 and 2010.

While at the Atlanta Beat, O’Sullivan coached USA National team players, Hope Solo, Tobin Heath, Lori Chalupny & Angie Kerr; also present were many top international players, including Japan’s captain Aya Miyami, 2008 Hermann Winner Mami Yamaguchi, England’s Eniola Aluko  and current Damallsvenskan stars Johanna Rasmussen of Denmark and Ramona Bachmann of Switzerland.

Before coming to the Beat O’Sullivan was a professional head coach in the Icelandic Premier League for three seasons. However, it’s at the NCAA Division II level where O’Sullivan has made his mark, serving as head coach at Christian Brothers, West Georgia and now Clayton State.

O’Sullivan was head coach for both the men’s and women’s teams at Christian Brothers from 1997 to 2003. He posted a record of 87-19-3 with the Christian Brothers women, leading the Lady Bucs to three straight Gulf South Conference championships, an NCAA Division II national runner-up finish in 2001 and the NCAA Division II national championship in 2002.

As the men’s head coach, O’Sullivan went 61-49, leading the Bucs to the 2000 Gulf South Conference championship and advancing to the NCAA Division II "Sweet 16."

From Christian Brothers, O’Sullivan started the women’s program at West Georgia. After the inaugural season in 2004, he helped pace the Wolves to a 13-7-1 mark in 2005, advancing to the Gulf South Conference Tournament semifinals. Overall, O’Sullivan has a 193-96-16 record at the NCAA Division II level, including 124-40-9 as a women’s head coach.

He was a three-time Gulf South Conference Coach of the Year selection. While at Christian Brothers, O’Sullivan coached three Division II All-Americans, including two-time Division II National Player of the Year Missy Gregg.

Throughout his soccer coaching career, Gareth O’Sullivan has built a strong reputation when it comes to developing teams into championship-caliber programs. He proved that with an NCAA Division II National Championship at Christian Brothers and is already bringing that same desire to the Clayton State Laker women’s soccer program.

After two seasons, Clayton State women's soccer is well on its way to championship stardom under the watchful eyes of O'Sullivan. Taking over a Laker program that had recorded only 11 victories combined in its three previous seasons, O'Sullivan has led the team to back-to-back winning seasons. In the process, the Lakers have boasted seven All-Peach Belt Conference and two All-Region selections in the last two years.

Prior to his first head coaching position, O’Sullivan played in the League of Ireland Premier Division with Sligo Rovers. He also had stints in the USISL, A-League and CISL. He also spent time training with Swedish teams IFK Goteborg & GAIS and 1992 English Premier League team Coventry City.
