If you search, you will see Dr. K of UPMC has a huge GK pt. study. His success record is undeniably good. Mayo Drs. 'toot their horn less', in my opinion. I think it's because the name, "Mayo", assumes quality care. Well, maybe or not... They certainly are busy!!
Undoubtedly, Dr. K has performed GK on more pts. than Link who also performs microsurgery, and really, prefers it, I believe.
