I've been going to Dr. Assadinia for 8 years, and he is by far the best dentist I've ever had - and I've gone to more than a few over the years. He's fast and has done excellent work on my teeth with little or no pain. He rarely charges more than what my insurance pays, and when a porcelean crown he put on my back molar broke due to stress, he replaced it with a stronger gold (or titanium?) one at no charge. My wife also goes to him, and we've both had excellent service from him and his staff. After we had work done that required meds, he even called us at home later to check on things.
I don't understand the bad reviews and the so-called "victims" who don't give any specific information about what they claim went wrong. The place is clean whenever we go there, and we've never had an issue with our insurance or his work. The problem with these websites is that it's too easy for a competitor or someone with a bone to pick to go on and fill it up with bad reviews. I don't know what happened with these people, but their vague claims are not consistent with our experiences with Dr. Assadinia in any way. We think he's an excellent dentist - see for yourself.
