I have 2 Excellent Doctors in Las Vegas plus more at the MAYO. I did fire 4 prior doctors in Las Vegas for I felt that they looked at me as little more than a meal ticket after "treating" me for several years. If you suspect that your condition is not fully explainable or there are missing links - everyone should go to a major research institution as it's their specialty to solve puzzles. I'm very happy with The MAYO and have met people in Las Vegas that are also extremely happy with their diagnosis and treatment at the MAYO after spending years in the Las Vegas Medical Death Spiral.
