"Mike Sewald is a proficient instructor. Through years of being an instructor, he has perfected the teaching methods of PDR. I feel confident, that because of my training, I will be able to compete with far more experienced techs that have had sub-par training. Mike is direct and tells you exactly how to improve yourself. The course he offers is well rounded and explains in great detail, all aspects of the PDR field. If I were to do it over again, I would go through his course and recommend that anyone else do the same."
