Hi Havasu, I lived most my life in AZ, unfortunately I wasn't DX'd until I moved to OK so I can't tell you right off hand. But here s a list of the Rheumy's in and around the phoenix metro area. Check out the site you will be able to get a feel for what others think of them. Plus it will give you their address and number.
