Mr.Trefz is greatly misunderstood. Yes, he is quite quiet, and no, he doesn't exactly have the most exciting lesson plans. But he has a good heart, and is really sweet. You just have to listen to him

Great teacher, easy to approach and talk to. Maybe if people in class actually listen to him, they'd understand what he's saying :P

Trefz's class was difficult in the beginning of the year, but it easier now. He would barely help me and wouldn't go over a problem that you found hard if he thought it was easy.

I had Mr. Trefz last year, and I liked him. If you do your work and dont mess around he wont get mad. I think he's a good teacher and I liked his class alot.
