El rio is horrible, I would never send anyone to them. They told me I had four cavities, which I didnt believe. I decided to just go back to the dentist I had seen as a child and was glad I did. I had no cavities, and the fees were exactly the same as El Rio. This was four years ago and I still have no cavities. Please dont go to el rio, research costs of other dental offices and you will see that they are not cheaper
