We started at Cortez and Assco. when my daughter was 3. We had good care when he was in his old office. His current staff is rude and not helpful. To keep up his nice office he has started recommending expensive non necessary procedures. I did do some in the begining, but got worried and went to get another oppinion. two others said not to do it! My daughter is in braces through their ortho and I have NEVER been more unhappy with a doctor/dentist. It has been more than double the time they said it would take. And I just found out from another dentist they are not even close to being done!! Dont go to this office!
