However, to call it a true concierge practice would be a joke, in my opinion. I've never had the money for one (10k+ per year fee), but a friend of mine did have one of these, and at least in his case they were able to cure a serious back problem of his through cutting edge and non-invasive therapies. I wouldn't expect to find anything close to that at One Medical.
Still would say the One Medical membership fee ($200) is worth it if you can find a decent doctor there and if you're not happy with what you currently have.
