I got the Groupon deal like others. It's well worth the money, time and energy for a basic introduction to photography and your DSLR. Dean is fun, attentive, and goes out of the way to assure each student understands their individual camera (without concern for the manufacturer or model). Dean also invites students to send him questions after class if needed via email. It's a great service approach based on a professional who respects his craft and customers.
Go for it and use this business.
