    Dr. Yen is the consummate professional... I am in the process of having all my teeth restored after cancer n yrs of chemotherapy which destroyed the enamel on my teeth... I was referred to Dr. Yen by my superb primary dentist Dr. Nishimura for a problem involving a back molar... n crown lengthening... Dr. Yen performed a consultation on the issue n what options I had to resolve this problem... I felt so confident in his knowledge n expertise that I let him make the final decision... my care has been expertly coordinated by 3 outstanding dental craftsman's Dr. Yen... Dr. Nishimura an Dr. Curtis... what a fantastic team!! I'm half way through my journey... n couldn't b happier with the results so far... Dr. Yen n his team are dedicated professionals n making the most positive outcome no matter what the situation or challenge... I am forever grateful n thankful for the whole team taking on my case with positive happy results... I highly recommend their dental services... u won't b disappointed

    I owe many thanks to Dr Nelson Yen. I had a "multi-stage" regenerative replacement of my front tooth by extensive bone grafting... Dr. Yen chose not to charge for the 2nd graft; he's a man of integrity & insured a stable platform. He outsourced the artistry for matching my unique teeth opalescence & striations. He continually consulted w/ my dentist regarding achieving superior results in forming my balanced gum line. Folks, this is an extremely professional organization; from check-in to assistant, to Dr. to Shari in scheduling... I could go on but I'll leave you w/ this question; when was the last time your Dr. phoned you to see how you doing after a procedure. WOW - enough said! As a former satisfied patient, I will accept inquiries by phone at 714-904-6596.

    I'm a dentist snob so I visit the dentist 3-4 times a year. Everyone is my favorite person here…read morelol. Rocio is the front office girl and she's always so jolly and fun to talk to. My teeth are really healthy so I don't see the main dentist often but the couple of interactions I've had with her have been very kind. But my absolute most favorite person to talk to and get my cleanings done with is Huang. She's so down to earth and easy to talk to. She's careful and wont wet you and poke you on accident. She explains everything she does. And the whole cleaning experience feels like a spa! They even give you a hot towel to clean your chin/mouth area up when you're done. There's snacks in there and drinks. Everything is clean and the outside area is adorable. I don't have trouble parking and I don't have to wait. Just walk in and they are ready for my appointment! I saw a video online recently that said it's actually very difficult to find good dentists to do cleanings because many are shady and will only have their dental assistants polish your teeth. I do not have that experience here. The technology is modern and advanced, even some of my old dental places didn't have what they have here. Note: I am a cash paying customer. I do not go through insurance. It's a little expensive compared to other places but you get what you pay for. The experience is much much much better here. And for anyone worried about dealing with people who have accents from their home country, that's also not the case here. They speak fluent English with no accent. Which I know is a weird comment but I think some people care about that. So don't worry about it. It's also super cool that the dentist and hygienist are sisters lol. How they don't drive each other crazy is so cute. You're the best Huang!

As someone who has had bad experiences with dentists in the past and suffered from anxiety--especially when it came to dental visits--I remember thinking, right before deciding to go, "Here we go again." But that feeling became a thing of the past after my very first visit. All Day Smile / Dr. Pham and the entire team go out of their way to ensure you're comfortable and clearly explain everything you need to know. The team is extremely professional and consistently go above and beyond to provide exceptional dental care. Once you enter, Rocio will be there with a smile to ensure you're welcomed and get everything situated! The staff is always friendly, and it truly feels like a family inside. They are never pushy when recommending products that would help and always respect my decisions about which treatments I'm able to do at the moment. The environment itself is extremely well-maintained and decorated so nicely. You can feel the love and care they put into the space. Not to mention, they stay up to date with the latest advancements in dental technology. I cannot recommend All Day Smile enough. You're never just a number when you walk in--which is often how I've felt at other clinics. Here, you matter, and you're genuinely cared for. All Day Smile is truly one of a kind. I can't stress this enough. -Omar

    I was on vacation recently and one of my teeth broke off at the gumline. I knew it had to be…read moreextracted and I wanted a replacement in the form of an implant. I had lost the tooth behind it last year due to another fracture. I had serious issues and needed help. I consulted with Dr. Clem and he performed a 3D scan of my jaw. After analyzing, he felt that not only could he extract the broken tooth, but he would be able to get another implant into the space left last year. We scheduled the surgery and it was performed this last Friday. It could not have gone better! He did quite a bit of work that day involving everything from extraction to bone graft to implant placement (different areas, mind you.) When I awoke from the sedation I couldn't have been more comfortable. What I thought was a hopeless situation has turned into future teeth. On another note, I doubt if you'll ever see a more high-tech office in your life. It is a beautiful facility with all the latest equipment. It's pretty obvious from the minute you walk in the door, this is as good as it gets! Add to that the fact that he's pretty famous in the dental world. He was President of the American Academy of Periodontology and still teaches at Loma Linda University. You'll feel very confident in this office!

After I was charged $120 for an eval I called my insurance ( Delta Dental of Washington PPO) to confirm if I was eligible for an exam free of charge. I was told by my insurance to demand a refund because I should've never been charged for my visit at Dr. Yuns office. I go back into the office and let Lorraine know I just got off the phone with my insurance and they said I should've never paid anything for my visit today. I then asked Lorraine if she ever check their system website to see my eligibility and insurance benefits. She told me " no I never checked it " WHY WOULDN'T YOU CHECK OR RUN SOMEONES INSURANCE ??! People now days are so LAZY and so quick to charge patients it's very sad. Yes I was refunded my $120. PLEASE ADVOCATE FOR YOURSELF OR YOU WILL GET SCAMMED! TRAIN YOUR EMPLOYEES PROPERLY!
