Caring and competent doctor. If you need a sleep study, I'd recommend this one. The staff is fine. For Las Vegas, I guess you could say they're excellent, since so many are rude and unprofessional. The wait time can be a bit much. But he's a good doctor, so you put up with it. Prices are expensive, with or without insurance. He was kind enough to make certain concessions to help us on something that was not covered by our insurance.
