    Shout out to Brooke the Registered Dental Assistant at Dr. Field's office who has gone out of her…read moreway to get me feeling comfortably settled before the three lengthy procedures I have had in the last month. She was well-mannered, professional, thoughtful and patient, answering all of my nervous questions and just did everything right. Compliments to Susy F the Treatment Coordinator again as well, for her professionalism, being on top of everything and kindness and patience in continuing to answer my remaining questions since I still have 2 smaller procedures left to do. Everyone at Dr. Field's office exemplifies Concierge Dentristry. Think of regular commercial airlines as being the usual dentist's office - and Dr. Field's office being the latest Gulf Stream G700 private long range jet. And Dr. Field is THE BEST. What he did with my mouth is nothing short of a total transformation, health wise for my mouth , bite wise and appearance wise. My new smile (26 teeth - 12 uppers and 14 lowers) is getting praises from everyone for looking so natural and pretty! Which of course makes me smile all the time now:)

    Dr. Karl Supal and one of his assistants, Evelyn put a crown on. I went in at 9, out by 11:00 with…read morethe crown done on site, no need for a second appointment. I can't say enough good things about them. Dr. Karl has an incredible skill at performing his magic. It didn't even hurt. He is the best of the best as he's performed other work I needed. I hesitate to write this since I want to be able to get in to see him in the future but he and the staff are so deserving. If you're one who has dread or anxiety visiting dentists, he's your guy. You'll be writing the next 5 star review. All the staff are competent and pleasant to deal with.

    I've been a patient of Dr Kwon's for a few years and finally decided to write a review after my…read moremost recent visit. I should have written this a long time ago. I went in for a routine cleaning and Gayle was absolutely phenomenal. I couldn't have asked for a more friendly and personable hygienist. She genuinely made the experience pleasant and enjoyable. Dr Kwon and his team are the absolute best. The facilities are immaculate, service is stellar and there is an obvious focus on fostering relationships. The care he extends to his patients and the community is apparent to anyone who has spent any time with him. For those that have never been to the office, it is the cleanest, most technologically advanced dental office you've ever seen. I can understand why some people think it is corporate owned. They couldn't be more wrong. Grace Dental is a family owned small business with an exceptional owner in Dr Kwon and his wife who are simply professional beyond belief, take pride in their business and pay attention to the smallest details. If you're looking for a dentist that is amazing at what they do, provide amazing service, and are relational, this is it.

    I recently visited this dental office for a routine cleaning, but the appointment turned out to be…read morefrustrating and heavily rushed. Despite booking a full-service cleaning, the hygienist spent nearly an hour touring the facility, asking extensive dental history questions, running scans, and reviewing potential treatment plans--with the dentist briefly stepping in at the end. It quickly became clear that this prolonged diagnostic process was just a setup to rack up exam fees and manufacture a reason to push costly, unnecessary treatments for profit. After all that administrative and diagnostic time, the actual physical teeth cleaning lasted less than 10 minutes, only for them to tell me I suddenly needed a deep cleaning. Spending an hour padding charges and pushing over-treatment only to rush through a less than10-minute cleaning does not feel like quality patient care. Won't be returning.

    Absolute crook, MONEY HUNGRY, taking advantage of the Korean community, especially the older…read morecitizens. #1 Dr. Yi is a prosthodontists, and should not be focusing on implants and root canals. Every patient he sees needs an implant or root canal. He is not interested in saving teeth, because that would be far cheaper than an implant. "Prime IMPLANT Center"...but that is not his area of dental specialty. #2 He is so rushed and cares 0% about his patients. He doesn't disclose all the risks and side effects of the procedure (personal experience and heard from others too). He brags about teaching as UCSF and pouts about how successful he is.. sending his children to private school and living in Palo alto...blah blah. Do some dental volunteering work if your that rich. Dr. Yi and his staff have made a good living by scamming every poor patient (that could have had their teeth saved) by imposing an implant or root canal for them. Avoid at all costs and keep your money and teeth.

    Got my wisdom teeth pulled out here. And before that, some cavities fixed…read more Dr. Yi really knows what he's doing. He is meticulously skilled at what he does. He is the only dentist my dad actually trusts! Haha. But not only that, while I was pretty much scared out of my wits before getting the wisdom tooth extraction, he really had concern for me and told me to take deep breaths and asked me every now and then if I was alright. Not just a scary dentist doing his job with the teeth, but actually a doctor taking care of his patient. Just really awesome. : ) Thank you Dr. Juhyong !
