Jeff is a great teacher, very humorous and very likable. His classes aren't difficult and really nicely paced. As long as you pay attention and get the work done, you will breeze through his class, but why do that we can slow it down to listen to Jeff's jokes and funny stories.
Jeff is a great teacher with years of experience and insight. I took two of his classes and enjoyed them thoroughly. His classes can be tough, but you'll learn a lot.
