I am in my sixth year as a teacher and I still think back to Mr. Rykken's classes. He is in the top three teachers/professors I have ever had the privilege of having.

I'm about to graduate college and I STILL consider Paul Rykken to be one of the best teachers I have ever had. Take every single class that he offers
