“Dave was possibly the best instructor I have had in my career. Very knowledgeable, thoughtful and engaging. Kept my interest in the class through all 5 days. Course material was great; but I was most impressed by the instructors.”

“What makes a 5 day training bearable is the people who teach it. Dave is talented in keeping us engaged throughout. He keeps it interesting, funny, and helps us understand the material. I also love seeing his cat pop up from time to time.”

“Charismatic teacher, loved the jokes. I was intimidated the most by this content but Ralph made it very acceptable.”
