Stony Brook University Athletics

In his first season with Stony Brook, O'Brien helped take the program to the next level, playing a key part in the team's second consecutive America East regular season title and its second tournament title in three years. 

Mainly working with the goalkeepers, he had Sofia Manner under his direction, who finished the season inside the top 50 nationally in clean sheets (8) and total saves (90). On two separate instances this season, she recorded three consecutive clean sheets, helping Stony Brook record just one loss in league play.

He joined the Seawolves after one season with Mercy College, a school located just west of White Plains, N.Y. He led the Mavericks to a 12-3-2 record a season ago, advancing to the semifinals of the East Coast Conference Women’s Soccer Championship and earning a berth in the 2018 NCAA Division II Championship.
 
Before his step into a D-II head role, the Southern Connecticut State graduate spent 12 years at Fairfield, becoming the all-time winningest coach in program history. He led 43 student-athletes to All-MAAC selections, with 23 of them being First Team honorees.
 
The former MAAC and United Soccer Coaches Northeast Region Coach of the Year also founded the women’s soccer program at his alma mater, going 105-56-8 during his 10 years with the club. He earned a 2000 Northeast-10 Regular Season Title and Regional Coach of the Year honors for an undefeated regular season with the Owls.
 
In his 23 seasons at the Division I and II level, O’Brien has accumulated a 236-158-51 record, including 119 of those wins with the Stags at the Division I level.
