For the past 2 years I have worked with Patrick at WallStreetOasis.com to create a user rich, feature expansive, high quality, and profitable web business. He was interviews on Mixergy.com, here is the interview. It's an interview about the site from a business perspective, not a development interview... however, it is pretty cool to see how happy a client can be with his web product. Patrick does day "... feel blessed to have the web developers I do have..." which was really nice to hear :). As an owner, Patrick is very knowledgeable about the power, features, and flexibility of Drupal, and articulates it pretty well... even defending Drupal against Wordpress :)
