Mr. Slepak is a great teacher! Though he may be strict, he wants every student to learn from their mistakes instead of continuously repeating them. He's really helpful too; if you have a question he's more than happy to answer it. He knows a lot about the music we play in class which is also nice because then we get some background info which is cool. Don't get on his bad side though. But if you just listen to him and pay attention you will love having Slepak as one of the band directors!!!!! :)

He's one of the greatest teacher's I ever had! My advice, work hard to earn his respect. That's the only way for him to like you. He was the reason why I'm going into Music Education.

Great teacher! Many people think that he favors honor band and that he is just mean, but that is not true. He is very informative, funny and really a great guy. When you say he is mean, think about how you would be if you had to direct 350 students.

People think he favors honor band over everyone else, but in reality, he has to take care of over 350 students. I think that for such an overwhelming number, he does a great job. If you talk to him personally, he is very nice, though he may seem very strict in front of a big group, so that he could get everything under control. He is a great teacher.

He had a reputation for being mean but he has to be strict to control the 350 people in the band. Overall, he is a goodnatured guy and, I think, a great teacher, but, don't be the goof-off in his class or your find your self in trouble.

I don't know him that well, only from summer band camp, so far, but he's a total perfectionist but he has two sides, really nice and really mean, gives really odd corrections on marching.

Mr. Slepak is insane. I enjoy the music he picks for concerts, and the marching music is fun. He is energetic, but powerful- watch out for that-, and wants the best for your musicianship.
