Alas, most insurance has a pretty strict list of doctors a person can see... but looking in New Hampshire might be a good idea.

From what I have heard, the further one gets from Boston, the easier it is to get an appointment. We have a severe shortage of primary care doctors around here. There are more specialists but even they book out months in advance. However -- for something that needs multiple visits, and for emergencies, once you get in for that first visit and establish a relationship, getting more visits in a timely manner is *much* easier.
