I like Koorhan. Good teacher and presenter. My second class with him so far and I'd take another.

Leslie was a great trainer and was well informed. He cared if students had questions.

I kept wondering if he has a PhD, he's very intelligent about the subject and many other topics. I feel that I was fortunate to be lectured by him.
