"I felt like they welcomed me with open arms," Broome told ESPN. "The program is an elite program."
"I love the way the guys there work, and I want to be around people like that," he added. "Everyone has a chip on their shoulder, from Coach [Mick] Cronin to the players, and I've always had that from being small and overlooked."
The 6-foot sophomore guard averaged 23.1 points per game last season at Sacred Heart to rank eighth in Division I scoring.
Broome, of East Hartford, Connecticut, will sit out 2016-17 and have two seasons of eligibility to play for Cronin and the Bearcats. Broome also visited Creighton before choosing Cincinnati.
Cincinnati was 22-11 (12-6 American) last season and lost in the first round of the NCAA tournament to Saint Joseph's.
