I'll echo what others have said - Dr. Cooper is an EXCELLENT dentist who not only does great work, he really cares about his patients. I discovered Dr. Cooper from the previous Yelp reviews and needed a dentist in AZ as I had moved from out of state.
In addition to the regular cleanings, I had to have some additional work done (replacing some old fillings that had failed and get 2 new ones) over the course of about 3 years. Dr. Cooper always told me exactly what needed to be done, showed me the issue on his comuputer (via xrays he had taken), and documented the work digitally so I could see before, during, and after shots if I wanted to. Dr. Cooper also calls you after a procedure to ensure that you are doing OK which I always appreciated.
Finally, Dr. Cooper wasn't on my insurance plan so they only covered "reasonable and customary" charges. Despite this, Dr. Coopers prices were fair and they always could give me an esimated out of pocket cost prior to doing the work.
If you are in need of a dentist in North Scottsdale, I'd highly recommend Dr. Cooper. I only wish I could still see him as I moved to CA but have already found another great dentist courtesy of Yelp!
