People here talk a lot about using a top 10% surgeon and Arnett and Gunson come up a lot. I notice that Gunson has less experience, only about 10 years. Is your impression that he's still a top 10% surgeon nonetheless?
I had the same concern looking at him.
It seems A&G do a lot of self-promotion. They spend a lot of time flying around, going to conferences, promoting their research...and maybe less time doing surgery than some other less well-known surgeons.
They may be great surgeons, but I think their brand-name is a bit hyped up.
