Im usually the type that dreads going to the dentist, but I came to Ontario Smiles about a year ago. What was a scary situation at the time, did not seem so bad. The staff was very friendly and accommodating. Dr. Loomba has been great, very gentle and makes every experience pleasant. They also are able to work with you financially which is also nice. Overall a great experience with them and I am very happy with their services.
