In 2011, the Gators finished the regular season 41–15 overall, 22–8 in the SEC, and SEC regular season co-champions—sharing the regular season conference championship with the South Carolina Gamecocks and Vanderbilt Commodores. After winning the SEC tournament, O'Sullivan's Gators received the No. 2 seed in the 2011 NCAA tournament, and advanced to their second consecutive College World Series, ultimately finishing as the national runner-up.

O'Sullivan has one daughter, Payton, born in December 2010, and son, Finn, born in September 2012.

O'Sullivan has also enjoyed recruiting success: his 2009 recruiting class was ranked No. 1 in the country by Collegiate Baseball Newspaper and Baseball America. It was the first time in Gators baseball history that a recruiting class was ranked No. 1.

In each of his four seasons coaching the Gators, O'Sullivan's teams have improved their overall win–loss record and Southeastern Conference (SEC) standing. In 2008, his first season as the Gators' skipper, the team finished 34–24 overall, 17–13 in SEC play, in second place in the SEC Eastern Division standings and third in the overall SEC standings. In 2009, the Gators compiled an overall record of 42–22, 19–11 in the SEC, in first place in the SEC East. O'Sullivan's 2010 Gators finished with an overall win–loss record of 47–17, 22–8 in SEC play, and SEC regular season champions. In each of his first three seasons, his Gators also showed post-season improvement, too: early elimination in the NCAA Regional in 2008; progressing to the NCAA Super Regional in 2009; and a berth in the College World Series in 2010.

O'Sullivan accepted the baseball head coaching position at the University of Florida on June 13, 2007, replacing Pat McMahon after the Gators failed to receive an NCAA tournament bid in either 2006 or 2007. Florida is O'Sullivan's first head coaching job; he is the twenty-first head coach in the history of the Gators baseball program. He spent the previous nine seasons as an assistant coach for the Clemson Tigers baseball team of Clemson University under head coach Jack Leggett, first as the Tigers' pitching coach and recruiting coordinator, and later as Leggett's associate head coach. During his tenure at Clemson, twenty-nine of the pitchers he coached were selected in the MLB Draft.

On September 1, 1998, O'Sullivan was named an assistant coach at Clemson University.

In 1997, O'Sullivan managed the Bourne Braves, a collegiate summer baseball team in the prestigious Cape Cod Baseball League, and was named coach of the year. His Bourne team featured future major leaguer Mark Mulder.

After his sophomore year, he transferred to the University of Virginia in Charlottesville, Virginia, where he played for the Virginia Cavaliers baseball team during his junior and senior years and was a member of the 1991 ACC baseball tournament All-Tournament Team.

O'Sullivan graduated Florida Community College with an associate's degree in 1989, and the University of Virginia with a bachelor's degree in sports medicine in 1991. He later earned a master's degree in exercise science and wellness from Florida Atlantic University in Boca Raton, Florida.
