Not only does Mr. Deggeller love math, but he also cares immensely about every one of his students. His class is lively and easy to follow; he speaks to students like equals and made my math experience at Gunn this year phenomenal.

he's really energetic about teaching and knows how to do it. he's also really practical when it comes to homework, he'll acknowledge how useless some of the other teacher's hwk questions are, and he'll tell us sometimes that we don't need to do any hwk even if the other classes do. also there really isn't any late system, i turned in a project two weeks late and he still gave me full credit.

Mr. Deggeller is one of my favorite people ever. He is absolutely hilarious and a fantastic math teacher. I missed a lot of school this year and he was always proactive and willing to help me catch up. He takes math concepts that seem complicated and makes them fun to learn. Also, he has FANTASTIC taste in music and can actually sing, so if you're into music you should definitely talk to him about that.

Deggeller is not only a terrific teacher, he's probably one of the most genuinely nice people I've ever met. He treats special needs students and lower division learners with the same respect and kindness as AP students. Probably my favorite teacher.

Mr. Deggeller was my favorite teacher at Gunn. He was so chill and had the geekiest humor (which makes you appreciate his passion for math)! He's really helpful and nice. All you need to do is the homework and tests well and you'll do fine!
