Hi Kathy and Welcome to Lapbandtalk
I was banded in Monterrey MX and have had 3 fills.
First by Dr. Lim under flouroscope (Penn. hospital, San Bruno, CA) via Dr. Pamela Foster.
The other 2 (blind) fills by Dr. Robert Mckeen, San Jose CA

I also know of Dr. Helmuth Billy of Ventra and Truckee (2 offices).
What part of CA are you from? Just South of the border there are fine Doctors that I don't know details on, but I'm sure Sue or Donali do.
