I worked with Andy when he was a Creative Director at Funny Garbage, a design studio in New York City. I found him to be knowledgeable, articulate, and lovely to work with. I learned so much from him at the beginning of my career.
In response to a previous comment: it seems silly to dismiss this class because Andy wears t-shirts with his blazers. If you think leaders only wear suits and ties, then maybe this class isn't for you. But if you want to learn from someone with loads of experience and a friendly manner, I really recommend it. You won’t be disappointed.
