The doctors list has been compiled over several years, so it could be that Dr Lawton did a successful surgery or 2 a few years ago & maybe doesn’t do the surgeries any more, we have had a few doctors this has happened with. I did a quick search of his name in the past discussions, & came up with some info on this one:
WARNING - GRAPHIC VISUAL INFORMATION: IJV Compression - Another Point of View - General - Living with Eagle
(It’s post no. 13 that @Isaiah_40_31 gives info & a link to another discussion about him)
So maybe he’s not doing the surgery any more- if you don’t feel confident with Dr Santarelli, then it’s worth getting another opinion, Dr Milligan in Pheonix is very experienced, although I’m UK so don’t know if that’s possible with your health care insurance…
