Hi, Greig, welcme to NeuroTalk!
Ours is a very friendly and helpful community. I hope you'll find some answers soon, waiting to understand what is happening can be absolutely maddening.
Using the nifty search option in the blue toolbar above, I was able to locate a list of threads that all mention Mayo at Scottsdale. Hopefully, some of these discussions will help answer that question for you.
