I agree with Heiferly, that you have to be assertive with Mayo and TELL them the specialists you want to see. They won't know unless you tell them in advance. That will make for a more efficient visit for you, since the docs will all be scheduled before you arrive. Once you see your lead doc, s/he can also schedule the tests and/or other docs you need to see, but that takes time. Plan on a 2-week visit (at least in Rochester), because the folks you see the first week may not be available till the second week. That's how it worked for us.
Mayo is very wholistic, but *caution*: with the Pediatric docs anyway, they like to steer you into the pain rehab clinic. In other words, they take your pain killers away and teach you to calm your autonomic nervous system with deep breathing, exercise, etc. That happened twice to my daughter, who got much worse after. She has EDS, though. Good luck!
I highly recommend Dr. Shibao in the autonomic clinic at Vanderbilt. Vandy also has an inpatient research unit that you might be a candidate for. That is where I met her, she was one of my attending doctors while I was there for research.
The only doc I'm familiar with at Mayo AZ is Goodman. I've not heard of Shen before, good or bad, so sorry I can't give firsthand input there. According to publications, Shen has worked mainly with Dr. Low, Mayo's guru of Dysautonomia/POTS:

From Mayo's website, it appears as though he was mentored by Low in Rochester before starting his career in AZ:

Looks promising to me?
In general, if you want to ensure that you get a more broad workup rather than just a narrow focus on autonomic, you need to make sure that both you and your referring physician make that clear to them that that is needed. Even if your referring doc isn't entirely with you in your belief that these abnormal immune labs are relevant, if you ensure that he passes the labs along as part of his referral anyway, then you can call yourself and impress upon them that the labs are abnormal and you want to make sure you are worked up by an appropriate specialist for that while you are there as well. Make sure you address each specialty you think you need to be seen by one by one, and that ample "evidence" is provided that you need to see those specialties by making sure your doctor passes along the relevant portions of your chart.
It's a lot of work before hand, but it will help you get the most out of your visit once you're at one of the big autonomic centers! I had my testing at Cleveland Clinic but Mayo isn't very different. There's been a disproportionate amount of negative feedback about Vanderbilt lately, so I'm not going to address them at the moment.
Let me know if there are other questions I can answer and welcome to our community!
