I used to live in Arizona and took my teenage son to see him once. He refused to go back to him calling him an arrogant !@#$%. And my son has seen a lot of docs and has never refused to see one. People in Arizona either love him or can't stand him and chose to travel out of state for treatment.
He is controversial in that he tells his tick born disease patients to avoid all magnesium. Even the amount in the bottled water here. He believes it feeds biofilm. Meanwhile, I spoke with many patients of his who had a lot of symptoms that were low magnesium: anxiety, muscle pain/cramps, insomnia, depression, etc. Many lyme docs will tell their tick borne disease patients to supplement magnesium because we are typically low between borelia using it up and the low soil levels here in the US.
He also is controversial in that he tells his patients that he can cure Lyme but it is other infections causing their chronic illness. He only tests for lyme with two bands using a lab that is not known for being a good lab to test for lyme. Then he tests for other infections using his own lab.
Do some patients improve under his care? Yes. But just know that many Lyme patients who live in the area chose not to go to him but travel to California or back east to see Lyme specialists.
If I were you and traveling from so far, I would go another 6 hours to southern California and see a different doc. One who is less controversial in the Lyme community and one well thought of. I don't know what the policy is here about using physician's names so you can contact me if you are interested.
Also know that if you go to the website that Timaca mentioned, they all love Dr. Fry on there. So you will not get a balanced opinion, plus it is only for Arizona residents. The owner will tell you he is great.
While in Arizona, be sure to stay well hydrated as the humidity is very different from the UK. I never left the house without a container of water. In the Phoenix area it was my experience that when you visited someone the first thing they would ask you when you arrived is if you wanted a glass of ice water. They understood the importance of staying well hydrated.
Have a good trip. I am jealous. Wish I was going. =)
Best,
