At Marquette, Barone will be responsible for assisting in the day-to-day operations of the office while also supervising the program's video responsibilities.
"Brian Barone helped me become a better coach my first two years at Marquette," Crean said. "He epitomized the idea of student-athlete with his toughness, talent and selflessness.
"I've been a big fan of Brian and his family for a long time and happy to have him return to Marquette," Crean added. "Brian has proven in his previous positions he's on the road to success in this business and I'm glad he'll be sharing some of those experiences with us."
Prior to his return to Milwaukee, Barone spent four seasons as an assistant coach at Illinois State University under head coach Porter Moser.
Barone joined the Redbirds after one season (2001-02) at Garden City Community College, working under head coach Earl Diddle.
He also spent one year (2000-01) at Central Florida Community College in Ocala, Fla. He helped guide the Pirates to an overall record of 21-11 and a Mid-Florida Conference Tournament Championship. The squad also advanced to the NJCAA Region VII semifinals.
Playing for his father, Tony Sr., Barone spent his first two collegiate playing seasons at Texas A&M. He was tabbed honorable mention all-conference as a sophomore and received GTE Big XII Academic All-Conference accolades as well.
He transferred to Marquette for his final two seasons, making his debut in 1999-00. That campaign was Crean's first with the University. Barone served as team captain during his tenure and was also named to the Conference USA All-Academic Team.
Barone earned his bachelor's in communications from Marquette in 2000 and completed his master's work at MU in the same field in 2002.
He is engaged to Mimi Gill and the couple plans to marry in August of 2007.
