    Newton Bui himself speaks both English and Vietnamese fluently, but everyone else (I believe?) speaks mostly Vietnamese.

    I really wanted to like this place because it was so nice and clean. However my issue was with the…read moredental admin department. This office is an absolute scam. They tried to push an unnecessary deep cleaning on me--even after I confirmed with my insurance (Humana) and my sister-in-law, a licensed dental hygienist, that I didn't need it. She personally reviewed my X-rays and said there was zero justification for that level of treatment. Despite this, the office kept insisting I needed it, then manipulated the billing codes to group procedures in a way that would force me to pay more out-of-pocket--even though my insurance covers 70%. When I called Humana, they confirmed the office was submitting things incorrectly. But instead of owning up to it, the staff tried to blame the insurance company and act like they were "just trying to help me save money." That was a lie. I wanted the office to send an appeal. They did not do that. They kept saying I desperately needed it but if I did then my insurance should have no problem covering it. They did not provide sufficient proof/evidence for the claim to be approved. It just didn't make any sense to me. I chose to text as a form of contact so I would have receipts of the conversation in case anything happened and I'm glad I did because when I re read everything it's just absolutely ridiculous how they handled the situation and how they dodged so many of my questions while I was trying to gain clarity. This place is predatory. They rely on patients not understanding billing codes or questioning treatment plans. It is so important to understand what your insurance covers because places like this will do everything in their power to make you pay up front and tell you insurance will cover it later. Then you'll realize your insurance will reject the claim snd you're out $500 of your own money. The whole experience felt like a setup to squeeze as much money as possible from me under the guise of "care." Do yourself a favor: get a second opinion, talk to your insurance, and run far away from this office. They are unethical, dishonest, and absolutely not looking out for your best interest. Also I want to mention if you look at the other 1 star review, you can see the another person having the same exact issue regarding the deep cleaning. I couldn't believe it.

    Thank you to Dr. Chang and his staff for being so patient and taking the time with me. I pray you…read morenever relocate or retire--no one else would put up with my annoyingly anxious self

    Dr bui did a root canal, crown cracked a year later, had replaced by a different dentist who said…read morehe's never seen such a hard crown in his life and no wonder it broke. I just currently left after doing some fillings, not once but for a second time in one week because they weren't done correctly, the first time. So after going back to fix it, they're even worse now Dr. Bui is literally telling me to just go eat food and that will fix my teeth and that the pressure in between my teeth is normal. I have never felt this uncomfortable from dental work before. I honestly dont know why I came back here after my first horrible experience. After telling Dr. Bui that I was uncomfortable she basically just told me to leave. I told the people in the front to which they said they would talk to her and she basically told them to tell me to leave. Horrible experiences all around. They refuse to even brush and clean your teeth before doing work on you. Not to mention the tools looked old and had rust spots on them. She did similar horrible work with a crown to my mother, trying to more or less scam her over, overcharging her. I don't know the exact story with my mother, but I know that my mother refuses to go back to her as well. To top it all off she's in there arguing with one of her doctors in the front office, shes clearly a difficult person to work with. That's probably why there's never a doctor that lasts more than a couple years there.

    Horrible they took forever and they don't clean their hair…read more Don't value customer time I waited for almost an hour
