On Monday, Custer, a 2014 lead guard out of Overland Park (Kans.) Blue Valley Northwest, found what he was looking for, as he committed to Fred Hoiberg and his staff at Iowa State.
"Everyone from the managers to the players to the coaches were genuine and I felt like they cared about me," Custer told Scout.com.
Custer, a 5-foot-11 lead guard, also said the relationships within the program factored into his decision.
"The relationships with coach Hoiberg and coach T.J. [Otzelberger] and all the players [stood out]," he said. "I have a good relationship with Matt Thomas, who is committed there, and is a really good guy, and Georges Niang is a really good guy."
"They are going to be my family for four years," he added. "We knew in our heart that was the best place for me to go."
A three-star prospect, Custer is currently ranked the No. 25 point guard. He is Iowa State's first pledge in the 2014 class.
