I would say that Mayo is one of the easiest medical facilities to visit alone. I’ve been going there for 12 years (sometimes alone), and find everyone to be amazingly helpful. Once I was standing outside kind of looking around, and a man asked if he could help me. He not only told me his favorite breakfast place, but he walked me there. I looked up his name later, and he was a neurosurgeon. So I echo another comment that Mayo doctors are much less likely to have oversized egos than doctors elsewhere. It is scary the first time you go alone, but you CAN do it!
