I have a concierge practice in Florida that I started from the ground up, and the demand has been very great. It took about 4 years to grow. In many ways, a concierge practice is much more demanding than my "traditional model" practice ever was. A big con for me right now is the perpetual call and inability to unplug. A pro is being outside of the insurance realm and contracting directly with your patients. Ideally, I would like to add a partner to help share hospital call and for vacation coverage. It's a difficult move though. It would be hard to convert an existing practice, inevitably dropping most of your patients. And to start from scratch is so slow that it is not often financially feasible. Other than that, I highly recommend!
