a few days ago, a recent graduate of a medical residency opened his own practice: dr parkinson. its business model is that of concierge medicine, but because it operates in williamsburg brooklyn, it caters to 18-40 year olds. it's gotten a lot of press in gawker, nypost, and wsj, where it resulted in lots of flames with dr parkinson replying. it's an admirable approach, both in terms of its attention to patients and to economics. follow his progress on his blog.
