@Sglass,
Sglass, is there any chance you can talk with one of those Harvard doctors and get a referral re the islands, or perhaps in SF (thinking UCSF or UCLA med centers)? Any chance you can be seen on the mainland? I figure that would be a time and money constraint, but just asking.
When I moved to new mexico, my bc surgeon (on staff at Stanford even though she and I lived and worked in Podunk) got me a list of names to see here. I didn't see any of those for insurance-bare reasons (a few months before I'd get medicare) and got hooked in, instead, at the University of New Mexico hospital clinics. I thought the guy at one clinic was incompetent (read the chart wrong) or, to put it more understandingly, was rushed. On the other hand, I'm wildly happy with the two surgeons I've dealt with at the UNM eye clinic, and I'm a medically spoiled person, as you intimate you are from Boston physicians.
Hang in there, kid, as Roberta and CJane would say.
