Most recently I had to schedule teeth extractions and wanted to have them done as soon as possible but the next appt wasn't until a few weeks away. The receptionist told me she would let me know if there was a sooner opening, and usually I feel like they just say that and never get back to you. But! I got a text a couple days later asking if I was available for a closer date, which worked out well for me. As anxious as I was about getting teeth removed, Dr. Kat made me feel comfortable and ensured I was numb every step of the way. Everything went smoothly, I didn't feel a thing. Even got to keep my teeth as a souvenir lol. I can't recommend them enough :)

I had such a good experience at Castro Valley Advantage Dental. The front office team, Maria and…read moreVanessa, were extremely helpful and kind. They made everything feel easy and welcoming from the moment I walked in. I originally came in that morning for an Invisalign consultation and they recommended removing my wisdom teeth beforehand. I was honestly really scared and unsure at first, but later that day I decided to go through with it and they were able to fit me in the same day. Kyla and Dr. Yuen made me feel so comfortable and at ease. The procedure went by so quickly and I felt no pain, which really surprised me. They were very reassuring the whole time. Carlos also helped me earlier that morning with fixing my mouth guard and he was super informative and patient. Everyone there is so kind hearted and caring. I really appreciate them so much and would definitely recommend this office.

I have referred others to them. I dropped them because i found the front deck people to be rude and pushy. Even though i was an established patient and always paid the day of service, they insisted on $800 for that days cleaning when i came in for my appointment, before they would work on me. $200 for the cleaning and $600 for Xrays. I said i wanted to wait on the X-Rays..she said they were manadatory. And she was snotty.. Then i said I'd pass on the cleaning. She seemed to care less. They have been bugging me for a cancelation charge, which i will never pay..i was the one who wasted a morning too. I am disappoiinted that we parted ways, but we all have options. I gave a 3 rating because half of the operation is great and half is terrible.

So, at this place I feel like when I walk in I hear the angels singing. And quite honestly, not…read moresure why they only get 3 stars... I had to start coming here because of a dental emergency. My tooth needed to be extracted, and fast. The guy on the other end of the phone said, "I can put you into Castro Valley Smiles for that soonest." YES... Frigging Yes... Please, yes. And so began our relationship. Now remember, I hate the dentist, any dentist, all dentists... Not here, nope. I love Dr. K... His really name is Dr. McDreamStormy. Really gentle, and listens very well, tells of all the options for your demtal needs and such. The dental techs also quite lovely. Thank you y'all for you kind service. But at this point in my moistly love relationship with CV Smiles it is YUNI that my hearts soars the highest right now. I wish I had the words to express my gratitude for this incredible woman. She's boss. She knows how to speak to people, treat people, and show kindness above and beyond. The reason for my last visit was horrible and I walked into the office sobbing, with one look Yuni fixed everything. She is a wildly compassionate darling that needs to be recognized. And appreciated. Thank you Yuni from all parts of my heart. Today you helped me tremendously and I honor your kindness. I will never forget you and this incredible Castro Valley Smiles!!!!

I am updating my review after another overcharge from this office. This time, I was overcharged by…read morethree times the correct amount and paid $3,300. After submitting a formal complaint to the DMHC (Department of Managed Health Care), they investigated and ruled in my favor. I am now receiving a refund of $2,060. Whenever I previously questioned the billing department about these charges, I was just given the runaround. I was even informed that if this office continues to overcharge patients, they risk being kicked out of the HMO network. They are really good at INVENTING overcharges. I am leaving two stars instead of one only because the female dentist here is truly nice. However, management and ownership (Dr. Lee) seriously need to get their billing act together and treat patients fairly. See the attached photo for the official DMHC determination letter. Dr. Lee, 똑바로 해!!

I've been coming here for the past 5 years, and I couldn't be happier with the care I've received…read more The dentist and the entire team are always professional, friendly, and attentive. They take the time to explain every procedure clearly, which really helps me feel comfortable and confident. The quality of work is outstanding, and you can tell they truly care about their patients' health and experience. I highly recommend this dental office to anyone looking for consistent, high-quality care

Unethical billing and patient payment practices…read more They do not disclose, despite requiring you review a LOT of paperwork before your appointment, that they charge a 3% rate on all card transactions until AFTER your appointment. The only sign about this is on the counter behind the door you go through to see the dentist so there is no way to see it before your appt. They'll accept cash, but they don't carry change. I won't be returning to be overcharged, especially in such duplicitous ways. Edit: The dentist and business owner has responded and clarified some things. I'm glad to hear they will be making it clear to patients before they enter for their appts that they will be charged an extra 3% for credit cards. Honestly, because we are charged a deposit for our appointment (I had to give a credit card over the phone when I called to make my first appointment) I hope this is made clear when a patient first makes an appointment or gives over cc information. While this practice may be common at small businesses it is not common at many medical offices. Also, when it was communicated to me at the desk I was told it was for all card transactions (including debit cards) when I attempted to pay for my services, which is why it felt particularly unethical. Not carrying change apparently means the extra is credited to your account. This was also never communicated to me when I expressed frustration with these policies only being shared with me after services already rendered while I was attempting to pay. I appreciate the owner receiving this feedback, but am nonetheless confused why I received such differing information at the desk than is being communicated here.
