A few friends of mine went to his lockpicking class and the guy is legit. I've emailed back and forth with him as well and seems like a nice and knowledgeable guy.
"In this class you will learn the fundamentals of impressioning. With persistence your new skills will allow you to recreate a key without ever seeing the original. The majority of the class consists of hands-on key impressioning, which is the processing of cutting a key from a blank by hand."
Classes are held at the Sector 67 makerspace in Madison.
