Dr. Yao has been my kids orthodontist for a number of years. He has always been attentive and helpful. He’s always available, even in “emergency situations ” after hours! I very much appreciate that. His office staff from front desk, billing, and assistants are amazing! I always enjoy talking with them! I highly recommended Dr. Yao, you will not be disappointed!

We couldn’t be more pleased to have worked with Dr. Yao! Our daughter had a fantastic results from her orthodontic treatment, superb personalized attention from Dr. Yao and his expert assistants, and they are very collaborative and working with us throughout the inevitable hiccups and problems that occurred. We cannot recommend Dr. Yao highly enough!

I love Dr. Yao. He is one of the good guys. professional yet personable. Friendly, has a great memory and truly cares about his patients. The entire staff is top notch. Patient, friendly and very accommodating. Highly recommended. I got invisiliners , although I’m 50 I wanted straight teeth and the correction is beautiful. My daughter will be getting braces soon and I’m certain her outcome will be just as good as mine.

Exceptional care and service by Dr. Yao and his staff! It feels like home. You walk in and everyone know your name from day one. Best costumer service I have ever received, because it was 100% genuine. I highly recommend Dr. Yao, if you are looking for an experienced provider, with excellent skills, welcoming smile, and a great supporting staff. I loved this place so much, I sent my nephew to see Dr.Yao. I would never hesitate to recommend him to any of my friends or family. I got my braces off today and I loved my smile. Never did I imagine the result to be this good. Now, I can smile or take a picture with confidence. Thank you so much for pleasant experience.

I am a male adult who like many had braces back in the day and since, lost track of the upkeep practice. A bottom tooth was severely out of alignment and top teeth narrowing with overbite. I hesitated to smile, it was probably distracting to others and more importantly, it was not consistent with my overall practice of self-care. From the first visit, Dr Yao was dialed into my needs and committed to my vision of a successful outcome. He patiently stayed with me, ran the process until my vision of perfection was reached. The net result, an amazing bright white smile that again reflects how I feel on the inside. I highly recommend Dr Yao and his professional, welcoming, friendly staff. Adults, you’re worth it, call Dr Yao and get that smile you deserve.

This is my first Yelp review! My son sees Dr. Yao for his orthodontic work and we are very pleased with the service and the experience. The way Dr. Yao works with kids is very friendly and pleasing so they feel comfortable. Also Dr. Yao clearly explains on process and procedures involved in treatment which is very helpful not getting lost in the dental jargon 🙂 . Dr. Yao’s office is great and the staff are very friendly. They have accommodated our frequent unplanned visits really well. I highly recommend Dr Yao and Team for your Orthodontic needs.

Eden P. from Bakersfield, CA (Source: Yelp)


After 17 years of Bay Area Orthodontics experience, It is absolutely worth it for my family to drive all the way from Bakersfield to Dr. William Yao’s Ortho practice for my son’s Braces appointments. I personally am thankful towards him and all the staff for treating every patient and parent with utmost respect and professionalism. The Best description I can give about Dr. Will Yao is his ability to work Smarter, not Harder. There is no other Orthodontist I would refer to, whether patients fly in from Utah or drive in from Fresno. I will forever be grateful.

Before committing to braces, I spent some time searching and meeting with doctors to find the right practitioner for my orthodontic needs. I have been very pleased with Dr. Yao and his team. He designed a great treatment plan, and always provides thorough feedback. The office has a positive and welcoming atmosphere too. Dr. Yao and his staff are some of most pleasant people you’ll ever meet. I’ve always had an enjoyable experience there.

Dr. Yao and his staff are amazing. We went to several places looking for an orthodontist for my son to get his braces. Once we met Dr. Yao it was easy to go with him. The office is nice and clean and his staff is extremely helpful. We moved to another state half way through my sons treatment and Dr. Yao is so great we decided we would rather fly our son back for his check ups than find someone new. My son got his braces off and his teeth Look amazing! Dr. Yao and his staff were supportive through the entire process. Thank you!!!

Jim T. from San Jose, CA (Source: Yelp)


How do you like me YAO? Yes, Dr Yao is a ROCK STAR! My daughter goes to him and she loves him. Actually, if you ask around in the industry you will find he is well liked and respected. Here is a person and staff that understands customer service. They are all fun to be with and to work with. Most offices you have to DEAL with, but I can’t say I have DEALT with them as of yet and don’t expect to in the future. The office brings you into the family, so much so that when you are sitting ringside, you never hear YOW!*#$#@ rather you hear YAO! I look good…. Really, you could go on all day talking about this office in a good way. Is it the office for everyone? That is only something you will have to find out for yourself. I do know that if I had to have braces, I would say Yo to the YAO!

Rosemarie N. from San Jose, CA (Source: Yelp)


Dr. Yao and his office staff have been incredible! From the moment I first walked in, I was impressed by how personable each of them have been. All of my questions have been answered in great detail and easy to understand ways. Dr. Yao is clearly proficient in orthodontics. But beyond that, what I was most amazed by is how truly cared for I have been as a person. It turned out that I am one of the rare cases that doesn’t tolerate Invisalign and Dr. Yao jumped through hoops to ensure that I wasn’t charged. I also happened to be going through a health crisis simultaneously and Dr. Yao reached out to me personally with care and concern. I would highly recommend Dr. Yao to anyone who is not just looking for excellent orthodontic treatment, but also someone who values you as an individual and treats you with genuine care! Praising God for blessing me with Dr. Yao!

We have been seeing Dr. Yao for over a year and we LOVE the office!! He takes such good care of his patients. The staff are really friendly and knowledgeable and the space is bright and inviting. moreover, there are lots of things in the waiting room for both kids AND adults! I highly recommend Dr. Yao for his amazing treatment results, customer service and his friendly and caring attitude.

Steve K. from Santa Cruz, CA (Source: Yelp)


All three of my daughters are patients of Dr. Yao and since I’m a general dentist I can say that Dr. Yao is a very knowledgeable and caring orthodontist. His office is very professional looking, clean and his staff is very friendly. He has a great sense of humor and makes patients feel at ease. I highly recommend Dr. Yao for all your orthodontic needs. He is very caring and will do whatever he can to get you the best possible result. A healthy beautiful smile is the goal for us dental professionals and he by far exceeds expectations for a beautiful straight smile. Now go get your teeth straightened from a guy who knows what he’s doing!! Dr. Yao thank you for all your good work!!

Leland L. from San Jose, CA (Source: Yelp)


Dr Yao has been working on my daughter’s (Makena’s) teeth over the past 8 months and I really appreciate the level of care, quality of service and friendliness he and his staff provide. His practice is set up with a very open concept with 4 stations in a large room. Parents are welcome to come in, and it’s arranged in a comfortable way where I’ve never felt my daughter was being crowded with people in her space as she’s being worked on. I like this setup because I can have a seat near my daughter and Dr Yao always points things out “real time” and does a great job of explaining what he’s doing, why and what to expect to both of us. I remember my daughter’s first appointment, when Dr Yao was reviewing her exrays, I was impressed with the time he took to really point out and explain a lot of the details, dimensions and ratios relative to different points of her skull, etc. – it was so interesting! Bottom line is that he took the time to explain, and was able to communicate it in a way we could understand. He also came across as being a perfectionist (which I like when it comes to my daughter’s teeth) and I still get that sense with every visit. So far our experience has been exceptional! Two thumbs up for Dr Yao and his crew!

Daniel S. from Santa Cruz, CA (Source: Yelp)


My daughter has been seeing Dr. Yao for about a year now and we are extremely pleased! Dr. Yao and his staff are always friendly and professional. During our consultation, Dr. Yao was very patient and kind to us in explaining the whole process. My daughter felt very comfortable and decided that she wanted to see Dr. Yao, even though it was a much further drive for us. I highly recommend Dr. Yao!

Absolutely the best Ortho office! I wish Dr. Yao was around when I got my braces done 20+ years ago! The knowledge, professionalism, and caring that projects from every individual whom works there is incomparable. Dr. Yao and his staff go beyond measure to make sure that every individual has an experience that exceeds their expectations. The office itself is one to be enjoyed from the moment you walk in! Coffee and tea for me and the other waiting parents, while games, books and contests are ready to be used during the short wait for appointments. I probably sound like a commercial, but seriously!!! Make your appointment now with the best Ortho office in CA!! Trust me- you won’t be disappointed!

Kristin O. from Sunnyvale, CA (Source: Yelp)


Dr. Yao and staff are amazing! When walking into the office, you’re welcomed into such a friendly environment. It’s like catching up with old friends. I feel very comfortable with Dr. Yao’s knowledge and guidance through my Invisalign experience. Any concerns or questions are answered thoughtfully and thoroughly. If i could give more than 5 stars, I would!

After going to several overwhelming consults at orthodontists closer to home, we decided to take the advice of several family friends and check out Dr. Yao. We are so glad we did! Dr. Yao is very personable and was able to clearly explain the issues and treatment options. He and his team have been treating my daughter for over a year now and we couldn’t be happier. The office staff is friendly, knowledgeable and on top of scheduling and handling those inevitable emergency appointments. The appointments run on time and I appreciate that they are able to give me an estimate on how long each will take based on the planned procedure. Thank you Dr. Yao and staff for making everything so seamless!

Dr. Yao is an amazing orthodontist with an excellent bedside manner. Let’s face it, getting braces suck but Dr. Yao really made it a great experience for my child. Quoting my child “Dr. Yao is really funny and motivating”. We had a few issues going on and Dr. Yao laid out a 2 year journey, clearly explained every phase, what to expect. He communicates clearly and patiently answers (the tons) of questions parents have. The end result? A brilliant smile and awesome school pictures!

Melinda M. from Campbell, CA (Source: Yelp)


We have had an amazing experience with Dr. Yao! He has been very effective and responsive to our needs! Also he cares about his patients as people and knows their names, not just their charts…. his staff is wonderful and they have various convenient appts for our busy schedules!! My daughter just got her braces off this morning and couldn’t be more thrilled with the results!!! Thanks, Dr Yao!!!

Fabiola T. from San Francisco, CA (Source: Yelp)


I can’t say enough positive things about Dr. Yao and his staff. Dr. Yao provided quality orthodontic treatment to my oldest daughter. It was an hour drive to come to his office, but it was worth it. Dr. Yao’s  hard work and dedication was consistent and  patient centered at every visit. The office staff were very helpful and extremely friendly. I would recommend Dr. Yao to anyone!

Dr. Yao is so friendly and professional! He made my daughter feel completely comfortable during all her visits. He explained the process thoroughly and made sure both I and my daughter felt comfortable getting a removable expander followed by braces. The removable expander is great for keeping her teeth clean and cavity free. She doesn’t have to wear it to school and it has removed the embarrassment of talking funny. It’s also easier to make the turns and adjustments needed by simply taking it out. Dr yao’s Office is thoughtful and inviting. There are various activities for the kids to do while they wait including fun contests and puzzles (although we never have to wait). There’s also kurieg coffee and tea available for parents. The office provides appointment reminders as well as special birthday messages! The office staff is helpful, friendly and works hard to accommodate our schedule. I cant say enough how happy we’ve been with dr. Yao and his office. He creates a welcoming friendly community in such an unexpected place!

Very happy with Dr.Yao and his team!! We started our first child with another doc in Los Gatos and were not happy with the results. A friend recommended we see Dr. Yao. We started kid #2 and #3 and we’re so glad we switched. Dr. Yao is super attentive and detailed..our middle child just finished and the results are stunning!!

Braces are no fun, but choosing a good Orthodontist can make things way easier. From Day 1, our experience is nothing but stellar! Dr Yao and staff are very knowledgeable and friendly, helping with all questions. They will work with you on the financial part, and I am very pleased. Our appointments are always on time, and Dr Yao takes time to explain the treatment and the plans. I am extremely happy with Dr Yao and all the girls. Thank you very much!

Tracy H. from San Francisco, CA (Source: Yelp)


Dr. Yao and his team are wonderful. After having braces back in Jr. High, I haven’t worn my retainer in years, so my teeth have slowly began to move. I decided to see Dr. Yao to get Invisalign. I needed to visit every 6 weeks to get checked and pick up my next 6 weeks worth of aligners. It was always very easy to get an appointment and the appointment itself was quick and painless. Dr. Yao and his staff are very friendly and put you at ease. Now I have perfectly straight teeth again and have learned my lesson that wearing your retainer is very important!

A B. from Menlo Park, CA (Source: Yelp)


Dr. Yao is so amazing! I am 38 years old and decided to get braces for the 2nd time in my life last year. He and his staff were super helpful and flexible in making it work out for me, my needs, my finances etc. I love that they are all happy and professional. Dr. Yao always tries to connect with his patients and seems to have endless energy and passion for his work and people. I am sure it hard to find a DDS who is great with both adults and kids – he’s taken it to the highest level. Ciao Yao!

Megan G. from San Jose, CA (Source: Yelp)


We had 3 consultations before meeting Dr. Yao and we did not feel comfortable with any of them.  None of them seemed interested connecting with my son who was a little anxious about the whole process, but more interested in boosting their own egos.  Dr. Yao made us feel at ease and cared for and just gave us a lot of confidence in him without boosting himself up.  His credentials and experience speaks for itself.  We’re very happy with our decision and looking forward to being a part of this wonderful office!

Chris C. from Cupertino, CA (Source: Yelp)


My son just started treatment here a couple weeks ago with Dr. Yao.  I was very happy with the results with my daughter so I already knew that with my son there was no other place I would have gone.  I can’t believe how advanced orthodontic offices are now.  With my daughter, Dr. Yao gave her braces (she needed them!!), but for my son, Dr. Yao said he could have Invisalign and that it would cost the same!!!  So to start they scan his teeth – no more slimy impression molding stuff – the technician did it in about 10 minutes.  Then some photos and basically in a couple weeks his treatment starts!!  Unbelievable!  I’ll update this review with progress report but I’m hopeful that my son will actually wear the Invisalign and get his teeth straightened without braces!!

Dr Yao and his staff could not have been kinder, friendlier or more skillful in helping me through the orthodontics process. I am a patient of a “certain age” and have had many medical experiences over the years and I have been delighted by the treatment and the outcome. I highly recommend Dr Yao for all ages.

Been taking my son for orthodontic work with Dr. Yao for the past few years. It has been nothing but a pleasant and enjoyable experience. This includes the staff as well. They are all very professional, respectful and work with a smile. The office also has a room for little ones (like you get siblings) to play as well a couch and coffee area, which is always a plus!

Rita G. from Los Altos, CA (Source: Yelp)


We have absolutely loved the care my son has received here for his braces. Dr. Yao is absolutely wonderful. he’s so patient and so very kind and does wonderful work. Everyone at the office is so helpful and happy and just great to be around. My son will be getting his braces off this summer and the whole experience has just been wonderful! Keep up the good work Team Yao! I highly recommend Dr. Yao for your orthodontic care!!

Jason L. from Sunnyvale, CA (Source: Yelp)


I just finished my Invisalign treatment with Dr. Yao and I am doing backflips!!!! Not only because I am done, but because the result is even more than I could have hoped for!!. My teeth look AAHMAZING and I’ve had multiple people stop me on the street to ask if I had braces and where – no joke!!! Dr. Will Yao’s name was given to me by a friend.I have been to many dentists before and this was truly one of the best experiences I have had. I had several choices a year ago before I started treatment here – in fact, my dentist sent me to anther orthodontist. After interviewing both, it was an EASY decision, even though Dr. Yao cost a little more, but SOO worth it. My friend actually started with another ortho about the same time that I did, and he is not done yet and hates it!! super happy that I decided to come here for treatment!!! Thanks Doc and I promise to wear my retainers!!!

Had upper and lower jaw surger which required about 18-24mo of braces in total, before and after the surgery, with a lot of coordination with my surgeon. Dr. Yao has a really great personality, blending a positive enthusiasm with a high level of competence. The entire process was flawless and I feel the cost was excellent value for the quality of care. Highly recommend.

Dr. Yao and staff are awesome! I just finished my invisalign and couldn’t be happier. Very professional and personable office and I enjoyed my time there and I LOVE my new smile. Dr. Yao will work with you until you have perfect teeth. Also, I found it was easy to make appointments that fit in my busy schedule. Highly recommend Dr. Yao!

Christina S. from Los Gatos, CA (Source: Yelp)


I am confident that Dr. Yao and his staff are the best there is in the Orthodontics industry! When I contacted the office to book my initial Invisalign consultation, the receptionist was respectful, willing to work with MY busy schedule, and extremely compassionate when addressing my concerns. Their office environment is fun, upbeat, professional, and CLEAN! I actually look forward to my appointments because we always have something to laugh about, and the whole office is always joyful. I decided to move forward with the Invisalign treatment, and it’s been smooth sailing since the beginning. Dr. Yao has answered every one of my silly questions and concerns about what’s happening with my teeth, and his staff has made the financial side of the treatment understandable and easy to handle. I even received a check-in call from Dr. Yao the first weekend I got my trays just to make sure I was adjusting to them OK. So sweet! As far as I’m concerned, Dr. Yao and his staff deserve 10 stars. I have already referred people to this practice and will continue to do so, no questions asked!
