I just wanted to give good news. I just got a call from Mayo Clinic in Arizona and Dr. Brent Goodman is coming back to the Phoenix area. He is an autonomic specialist and has great reviews for Dysautonomia. They also have QSART machine, at least this is what I was told. I had to cancel my appointment at UCLA, no testing equipment and some other issues that I won't go into. Am going to Mayo in August and am so hopeful for some answers and help. I hope this helps anyone looking for a doctor in the Southwest or probably West coast area as well.
