"I thought that the self-teach training program was very informative and effective. We have taken TDG courses in the past and we felt that this was a much more relaxing way as we could all sit down and discuss items and issues together. This program receives a 'thumbs up'."

"Your TDG Self-Teach^TM was an excellent way to learn, self-paced, and you have all the time you need to read the booklet. Excellent course!"
