Radford led the Black and Whites to an 11th placed finish in Super League last season, leaving them five points off the play-offs.
“He is the perfect man for the role that I outlined to him. He understands the culture here,” Pearson told BBC Radio Humberside.
“We wanted to get the empathy back with the fans and have it represent what Hull stands for and Lee is doing that.
“He’s organising the club in such a way from top to bottom that I am very proud of the work he has done.
“It wasn’t an easy season for anybody last year but he has come through it and I believe he is ready to show what a good coach he is.”
Pearson also remains confident that the Black and Whites will be in contention in the play-offs in 2015.
“We’re all excited and looking forward to next year,” he added.
“We’ve got the momentum now, the players are all looking really keen and there is a buzz around the club.
“We’ve been really impressed by the new recruits and we think we’re going to push on and be a force in the top eight.”
