The only RE's I've heard of are either in Phoenix or Tucson. I'm closer to tucson. There are only 2 REs in Tucson. Dr Hutch.inson and Dr Gel.ety. I only saw dr g. He seemed to be high-fsh friendly, but I didn't like his personality or office staff. He does seem to be relatively inexpensive, but the staff does try to pressure you into getting labs done in-house, which aren't covered by insurance. I always get a slip to go to a lab elsewhere but they give me attitude about it.
