When you arrive in Arizona, stop at Mayo and get assigned a Primary Care Provider. For older peoople, it definitely helps if you have a Medicare Advantage Plan to beef up your standard medicare.There may even be a specific clinic for people who live locally. In Rochester, it's the Baldwin Clinic. Get to know your Primary Care Provider = he/she is the gaekeeper for referrals to specialists. Baldwin even has its own staff of specialists in the same building. If you knock on the door asking for a neurologist right away, you will get nowhere. Learn and respect the referral system used by Mayo.
