"An excellent teacher and trainer. He did a wonderful job teaching us and enlightened us further on a number of topics."

"The trainer was great. He explained the basics really clearly and was super helpful if we ever got stuck on something, and went at a good pace so that we could keep up without getting bored. The course manual is also really impressive. I would definitely recommend this course."
