Thanks folks.
Menon is at the top of my list. Absolutely. Ash Tawari is out of network, so not an option. Su at Hopkins, Patel at Ohio are also both right up there. But I've heard that (is it Smith?) there is a Dr. at Vanderbilt who is in about the same rank. Maybe it is Smith.
I know there are some other top da vinci surgeons but I have to keep my list fairly short in order to not mess up my insurance.
