    A very nice and caring doctor. Helped me get over my anxiety of having to have a root canal. His staff was great too.

    I've been going to Dr. Myers for many years now. I had an appt for cleaning, but unfortunately, I…read morehad to cancel a few days beforehand. When I called to cancel & reschedule, the soonest they could get me in with my hygienist was a couple of months out. They offered to put me on a waitlist for her. We usually hear about these infamous waitlists that never seem to pan out, but this time it actually worked! I was able to see my hygienist the very next week! I checked in for my appointment & as always, staff was very friendly & efficient. When I got to Michelle, she was her usual kind, sweet, caring self. Michelle is so pleasant to chat with, & has such gentle hands - I love my time with her! After my cleaning, Dr. Myers came in for my full mouth assessment (I'm making up what it's called, I have no idea!). This dentist is a pro - he checks your gums, teeth, bones, color, & basically everything in your mouth to ensure oral health & well-being. He addresses any concerns or questions too. I'm very happy I was referred to Dr. Myers so many years ago, & I'll continue coming here for their excellent service. Keep in mind - call any dentist prior to scheduling to find out what your insurance covers. I have DPPO & they were able to call my insurance & tell me what my portion would be. I'm not 100% sure if they take DHMO insurance.

This guy just wants to milk my insurance with a lot of unnecessary stuff. Would have ruined my vacation if my old dentist did not save me.

    It was my first time at the office. The staff is very nice. The office is very modern…read more Ashley my dental assistant was great. Dr Kim was great. They didn't push me to get a whitening service or a night guard or composite replacements to my already stable silver fillings. Efficient work and I was in and out in less than 45 mins.

    I do not trust Dr. Tadang. I saw him for two different procedures and both were unsuccessful. First…read moreone was to put on a new crown for cracked tooth that was seen by my endodontist during a root canal procedure. Dr. Tadang said he could not see it, so he just put in a new filling. I ended up having the tooth extracted several months later. Could it have been saved if Dr. Tadang did what my endodontist told him to? Maybe. Second procedure was to replace a different crown. He took an impression with his scanner and told me to wait until it was approved by my insurance. He calls me several weeks later and says my crown is approved but will not install it unless I pay him $150 for a gingivectomy that he never told me I needed. He was basically holding the crown hostage. There's a reason why he waited until the crown was approved - so I would hand over the additional money in order to get the crown for free. I went ahead and agreed to it because I just wanted it the ordeal to be over. He installed the new crown but my pain just became worse. He told me to go see an endondontist. I saw two of them and they both told me the root canal was ok but the crown may have been placed incorrectly. Dr. Tadang refuses to see me and even put a note in my file, so when I call his staff just tells me that I cannot come to the office and "Dr. Tadang has already helped you and go somewhere else." Totally inexcusable behavior. Btw, on my first appointment to this office, the staff was outside on the street talking and looking at their phones when I came to check in for my appointment, knowing that a patient was scheduled to come in.

    Dr. Nguyen was awesome today along with his staff. Very clean and modern office with caring staff…read more He explained everything in detail and made sure I understood what was going on and what treatment I needed. He also made sure I got a referral to a dental professional he trusts to complete my work. Couldn't have asked for a better experience!!

    I am a retired dental professional and in past years have worked chair-side for top Orange County…read moreDentists and Endodontists; both in front office and as a chair-side assistant. This guy is as arrogant as they come. But he has absolutely no reason to think so highly of himself, because in addition to his lack of chair-side manner, the endodontic treatment he performed failed. He attacked my tooth with such a vengeance that the root cracked and now I will lose the tooth altogether. He is rude beyond credibility; demonstrating a complete lack of patience and understanding for the comfort and needs of the person sitting in his dental chair. I suffer from vertigo and he literally stood me on my head; refusing to make even the slightest of adjustments to accommodate my condition. I asked him to please lower the chair slowly so that my inner ear could adjust and he wouldn't even do that much. His manner was gruff and self-serving. Run!!!!! He demonstrably indicates that he doesn't care about the patient, and is completely condescending towards them, no doubt stemming from his high opinion of himself. Just take a look at his photo, provided on this site. His demeanor say's "I am hot stuff and superior to you, therefore I am the only one who has a say in this scenario!" Excuse me sir, but I don't concur. The patient matters the most in my experience and according to the highest of professional values which I have observed from other practitioners.
