Sandy was wonderful, very quick to respond to my emails, and he made it very easy to set up my private group. Once we got there he was very informative and helpful, and taught me and my friends quite a bit. My son has raved over Sandy's teachings, and can't stop talking about how much he learned and how much better it has made him. I thought I was proficient, and even I learned things. I'm very glad I found Sandy and took the class. It was well worth the money, and the small drive.
