I graduated back in 1998 and Mr Cusack is the reason I now have the career I have. He inspired me to love mathematics, applied mathematics and physics. There is no doubt that he teaches the top tier of the class, but this is great and he is brilliant

Class of 2004. Mr. Cusack is one of the handful of teachers you will remember long after you've left. The man is a legend. And if you are smart enough to be in his class, you should get an A or at least a B with or without his help. He'll be there to help you if genuinely need it.

Hopless teacher. He should not be allowed teach. He does no class preparation, is 10min late for every class, and only teaches the A student

Excellent teacher who made potentially difficult subjects (mathematics/physics) easy. Almost as good as Ray Kearns. Can't say better than that.

Its easy to be considered a good teacher by the straight A Gonzaga Maths kids-If you actually had issues with the subject I found him a condescending letdown.
