I lived in Arizona for about 8 years, having moved from the midwest. I've been to a number of different dentists in Scottsdale and wasn't comfortable with any of them. Dr. Carson was recommended to me by a neighbor because of his professional and ethical standards, not to mention the quality of his work. My neighbor highly recommended Dr. Carson because of the quality of the crown he replaced, and said it was worth the drive. I had a cleaning and x-ray by his hygienist, and and followup thorough review by Dr. Carson. Dr. Carson was completely honest with me that I didn't need any additional work at this time. I give Dr. Carson 5 stars for his integrity. My experience over 60 years with dentists is that they always seem to find something that needs to be repaired or adjusted and recommend (up-sell) unnecessary treatment. It's comforting to know that one can get an honest assessment of your dental needs without thinking that you are being sold something you don't need. It was worth the drive and he will be my dentist as long as I live in Arizona.
