Echoing other comments here, I use One Medical and am an extremely happy customer — I pay the yearly subscription out of pocket. Online scheduling + video calls at any time with their staff make it well worth it, and they have offices in many cities and states so I've even seen doctors and gotten bloodwork + vaccinations done while traveling (domestically in the US). My experience with their doctors has generally been top notch as well, including one doctor visually and immediately diagnosing a family hereditary condition that had taken my sister years to get diagnosed through other doctors. And since they have so many offices, I can pretty much always get a next-day appointment in the Bay Area. I've never had to wait a memorable amount of time once I show up, and they can do a lot of labwork immediately onsite if you need or want it without additional scheduling or needing a return trip.

I've traveled and lived abroad, and IMO One Medical clears even the relatively high European-style medical system quality bar.

Happy for them that they got acquired by Amazon, since the scheduling + online stuff is a big part of what makes One Medical great and Amazon is quite good at that.
