Short version: every health care professional in the country should be required to tour this place to see how it's done.
Long version: Facing a possible serious health condition I grew tired of waiting for my primary to refer me to a specialist and called Mayo. They accepted my insurance (United Healthcare) and scheduled an appt within a week.
Leading up to my appointment I received 3 calls - preregistration they call it - each designed to make my first visit as fast and easy as possible.
For my first appt they actually had me in early. I had a lengthy discussion with a cardiologist named Dr. Click, who was professional, knowledgeable, genuinely interested and in no rush to just get me in and out. He scheduled three more appointments and within 15 minutes I had a printed itinerary. The first was bloodwork. Down one floor where I waited less than 15 minutes before I was in and done. The 2nd and 3rd were two days later and again I was admitted early.
Every single person I encountered there (10+) was pleasant and professional. Each confirmed my name and birth date to make sure I was who they thought I was...comforting to say the least.
After all of the tests were done I met with the cardiologist again and he went to great lengths to explain every detail to me, answer my questions and give his advice. At no point did I feel rushed or like I was just a number (or a payment on a summer home.)
The facility is about an hour from Central Phoenix but well worth the drive. For out-of-towners they have a hotel next door. I'd highly recommend Mayo to anyone and would probably fly family members out the next time the need arises.
