Student Reviews

"Tony is a personable and good instructor. He was very thorough with his materials that he covered. He was always willing to do whatever it took to accommodate our needs (and we had a few). I would easily recommend him. Our proctor, Bruce, also was very pleasant and put me at ease for our field testing. Glad we had them." - George Machuta

"I signed up and was instructed by Scott Hoover. He did an excellent job in instructing the course in an easy to understand format. He took the time to be sure all students understood exactly what he was presenting. He gave us his phone number to call with any questions, and made himself available to assist us at any time. Excellent Job Scott!" - Jim Heinz
