Do they have rheumatologists and neurology providers?

I not sure but they can give you a referral

That's probably something that they will refer you out to it's been my knowledge I'm usually referred to other doctors out of that office unless it's basic or routine check UPS

No they don't. They can refer you to one.

I'm not sure for that too. But I'm 100 % sure that they'll give you referral after you see them doctors first. Hope clinic it has a great doctors and great staff they always listen and have patience and will take care of you.
