      Thomas Guarnieri has 2 skill sets that make him exceptional. 1- He thoroughly understands Electrophysiology 2- He explains it in a way that is very understandable. He should consider a consultancy role in his retirement to teach young physicians the How and Why of explaining medical issues to patients. We need more Doctors like Thomas Guarnieri
