I currently have a concierge practice that I started de novo. My model is the strictly retainer model and I do not bill insurance. I have a staff of one and charge $1500 per year. I looked into adding insurance but it just didn't seem worth the hassle.
I absolutely love it as do my patients. I feel as if I am able to work smarter for each patient which in turn keeps them out of the hospital/ER, keeps them healthy, and also lowers their overall health costs.
