Xavier High School needs more people like Mr. Duffel. Mr. Duffel is understanding, nice and a great person. He is dedicated and is a great coach. When he talks to you, he talks to you with respect, unless you're an idiot in which case he will blast you into Hurtado hall with his flames.
He is unbelieveably awesome. I find him to be really cool. he also stands up for the students.
HE IS A GREAT GUY, A GOOD BASEBALL COACH AND BASKETBALL COACH
