Fascinating. Can't say as I've had any personal experience with them, but I know who I'm contacting now if I can't get my gall bladder to behave itself and it comes down to it. OKC is an absolute trainwreck as far as healthcare is concerned... this looks like quite the little hidden oasis, and it doesn't surprise me one bit that it's known internationally, yet the locals are daft to it.
Nords, if you ever find yourself needing to come out here... look me up. Our accommodations are humble, but you're always welcome. And I promise, most of the locals are pretty coherent.
