Gordon Moore, the father of the micropractice, is chronicled here. SoloDoc is mentioned as well:

Dr. Moore estimates that his overhead costs make up 35% of his revenue. That compares with a figure of about 60% for other small primary-care group practices, according to Medical Group Management Association, an Englewood, Colo.-based professional association for doctors’ practices.

A few weeks ago, Dr. Moore asked patients to rate the medical care they receive by using the online survey, “How’s Your Health.” About 450, or three-quarters of his patients, responded. About 70% said they had received the care they wanted, and at the time they wanted it. The national satisfaction rate, based on the same survey, is about 30%.
