The instructor Mike, was very knowledgeable to say the least. The magic he preformed on me, a 66 year old cantankerous grump, was to plant four days of material in my pea brain. Planted in a way I could remember it, repeat it and understand it. He took what could have been four very long days and made me wonder where the time went. CHC provided a friendly, clean and comfortable environment with all the materials and handouts as well as a note book, pen, highlighter, snacks and drinks. All I had to do was show up.
