No doubt you have researched them all including Bumrungrad in Bangkok with it's many US board certified specialists.
That one impressed me so much, I bought stock in it.
First of all if you think that physicians are the only thing that make a hospital tick you're sadly mistaken.And second of all,have you ever been to Southeast Asia? I have. And while it could very well be that the hospital you mention is good by Southeast Asian standards what I've seen of that part of the world...alone....would make me *very* suspicious of *any* hospital located there.
