Covenant is pretty easy to reach if you go east a bit. Unfortunately, there's no fast travel waypoint. If you already have enough radiation resistance, perhaps from the power armor in Concord, then this doctor might be worth visiting. The doctor is a ghoul, so the radiation doesn't bother her.

There's a doctor in a shack surrounded by radiation west of ArcJet Systems. There are a few doctors you could reasonably get to beforehand without going way out of your way, but they're neither a lot sooner nor much easier to get to, so you aren't missing out by just going ahead and continuing to Diamond City instead. The doctor in Diamond City was the first one I ran into in my first couple playthroughs. I know there is a traveling doctor in the area (having run into her), but I'm looking for one that is in a fixed location (or very predictable) that players can locate with constancy if they need medical care early in the game.

This question originally was: Is there a doctor consistently available before Diamond city? Given that people interested in this may well search google for terms like doctor, Lexington, Cambridge and Diamond city I am going to leave that in the text as well. If the map isn't available for some reason, this is roughly a 45 degree wedge from Cambridge up into the northwestern corner of the map. I'd suggest sticking to doctors that are in the areas of the map which are blue (accessible by most characters below level 16). If a more specific area is needed, you can reference this map on how dangerous areas are: This should be the doctor that is easiest to access by a low level character (assume the lowest level character that can reach any doctor), ideally close to Vault 111/Sanctuary. What's the easiest to access or first doctor you can access in Fallout 4? Of course more than one is welcome.
