The best dentist I ever know. I had very bad experiences in the past with other dentists. My teeth is not easy and I do have problems and I am very picky. Dr. O' Neill is one of the best dentist who have a passion for what he does. On my opinion he is very talented. He can give you an advice and for sure it will be the best one. Since I moved from Colorado I cant find dentist who would replace him. I do fly from MIami to see him when I need. If all of the doctors would care the way he cares I think we would have no problems. I have done in his office root canals, crowns, tooth extraction and cosmetic work for my front teeth.
