He should be able to understand the connection between lack of people in music/band, and a single music teacher in Streetsville. Could give more encouragement to students as well.

He ruined music for me and almost everyone in his class. He's not mean, he just doesn't know how to teach.

Good teacher, a lot of kids dont really like him and dont enjoy his class but i think he is very nice and understanding. He helps you out when you need it. He is currently my Buisness and Tech teacher and he helps me when i need it and for the most part, his lessons are clear.

Decent guy, but completely oblivious to what the students are doing when they're not playing.

Detweiler taught me BTT this year, and despite the fact that he didnt know very much about it, he was a pretty cool guy. I dont know why nobody likes him, hes so nice and he makes you feel welcome :)

He's a nice teacher, but only if you focus on this course and get it over with. He's not so bad, just so snappy sometimes, but he is an okay teacher in general.

I really think people should cut him some slack, he's really easygoing and extremely nice. I just wish Streetsville had a bigger music department.
