Dr. Vellequette and Dr. Fung are awesome I been coming to smile center for many years and I haven’t had any problems. The staff is equally as Great very welcoming and professional. Being the Silicon Valley they have all the technology to make the process as efficient and comfortable as possible. They even have Netflix as an option while you are being attended to! I wouldn’t go anywhere else it is well worth the visit.

Dr. Vellequette is the best dentist I’ve ever had. He’s been my dentist for about a year and a half. He’s super knowledgeable and it feels like he’s seen every situation before and knows how to navigate them. Extremely easy to talk to and the office staff is very nice. I drive from the East Bay to see him which is about a 40 minute commute each way, but still worth it.

Theresa E. from San Jose, CA (Source: Yelp)


I’ve been a patient of Dr. Vellequette’s for several years now and continue to be impressed by the high level of customer service and high quality dental care that I receive. Dr. Vellequette and his team of professionals make going to the dentist a positive and relaxing experience. He and his dynamic team provide a friendly, calm atmosphere and treat each patient with sincere care. I highly recommend Dr. Vellequette for preventive care, dental treatment and cosmetic dentistry.

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


I have done a lot of work there so far, filing, wisdom teeth extraction, etc. Dr. Vellequette is awesome!! Recently I chose to do cleaning there too, the hygienist did not let me down neither. Schedules are flexible. People are nice and professional, and instruments are clean (have to!!!). I can imagine myself doing all the dental work there in the long future, as long as they keep up with the cleanness, professionalism and nice staff!

Everyone I have come across at Smile Center Silicon Valley is utmost qualified. The whole crew comes together as a smooth operating team. I have been going to Dr John for more than 4 years now and his expertise and empathy was great, and helped me overcome some pretty complicated and painful dental issues. Jonny, and Melissa are two of their outstanding dental assistants who consistently listen to any needs for adjustment and make sure you will have a comfortable visit.

Parul B. from San Francisco, CA  (Source: Yelp)


Dr. Vellequette and his team are caring and efficient! They work with you to get to the bottom of dental issues and provide solutions to opt for, what makes perfect sense. As well as provide pricing for what work needs to be Done. I don’t feel rushed and in case you are in a rush then they will accommodate and help expedite your visit. I like that it is a very clean and well kept office, hygienic dental office!

Jim G. from Woodinville, WA (Source: Yelp)


I love my dentist !  First, he has been a dentist for many years, so he is well experienced in his field.  Second, he has always had the latest equipment to make my visit the most thorough as possible.  Third, he only requests additional work when he feels it’s necessary to prolong the life of the tooth.  I usually go in for cleanings twice a year.  About every other visit, the Dr. performs a tooth examination once my teeth have been cleaned.  Although he may indicate a “watch” here or there on a tooth, he isn’t the type of dentist that immediately requests additional work to be performed; just to get additional income so he can pay a car payment.  Instead, he will mention “we’ll keep an eye on that, but nothing necessary to do just yet”.  The office is always clean and the staff is always friendly. Keep up the good work….. until my next visit.

Service is very timely, I even came in early once and they started right away(likely due to a more open schedule, but still demonstrative of their willingness to accommodate). The staff are very descriptive and explicit about your dental health, as they should be, but in a very positive and constructive way. Ask any questions and you will get honest answers. Also, they are friendly people, and won’t bite (that’s your job!) so don’t be afraid to be conversational!

As a first time patient, I had a great experience at Smile Center Silicon Valley, today. For me, having a great hygienist, is one of the most important parts and I strongly recommend Michelle! She is seriously one of the best ever! I just recommended my wife go see her. The whole team was great and Dr. Vellequette was excellent! Also, none of that high pressure sales for extra services that’s we’ve occasionally experience with other practices…

Dr. John Vellequette here in Sunnyvale, CA is punctual, professional and gentle with his patients. I have been seeing him for over 3 years now, and I have always been treated with respect and my dental work is always done right the first time. Dr. Vellequette is very professional and highly skilled cosmetic dentist. I was extremely happy with the work he did on my teeth.

Unbelievably… simply unbelievably!!! Dentist John and his team continues to exceed my expectation of beyond-excellent service and most knowledgeable and informative dental team!! From the moment I enter Smile Center, Angel is there to welcome me with her sweetest smile and greeting. Quick checkin and personalized chat during the walk to my comfy & clean & media equipped room. Then I was in good hands with Carrie. I can’t believe Carrie took pictures of all the angle of my teeth and zoomed in even more precisely on the problem areas that were identified back in my last dental visit in 2016 (no dental insurance but thank Angel for informing me of Dentist John’s Membership which covers 2 cleanings, x-rays and exams and discount of Dentist John’s expert read on anything that could be wrong with my teeth). Then Michelle was introduced to me and she was so knowledgeable about what was causing my sensational shots of pain in my upper left quadrant. Best cleaning and polish ever! But that was not the end to my Membership visit, the main attraction enters my room with the warmest welcome and took his time to educate me of the problem areas from 3 years ago and how Carrie’s x-rays and precise angled pictures shows the current conditions. Instead of trying to scare me to get more services done, Dentist John gave me easy to understand layman examples of my teeth conditions: what is the condition, what caused it, how everyday chewing puts stresss on it and what treatment plan needs to be implemented to fix my problematic teeth aches. Then Urly enters with the cost breakdown with the Membership discounted to my lowest possible price all without having to deal with enrollment into a long wait period dental insurance! Angel scheduled my return appt and I immediately prepaid another Membership for my 6.5 year old daughter and set up her cleaning, X-ray and exam next Wednesday. Once my parents visit me from Boston and my in-laws visit me from Philly, I am making sure they see Dentist John and his amazing team… a second opinion from the ‘most expert’ dental team confirming all our Oral Health is a must for my family now (after 3 years of no dental anything). P.s… did I mentioned that my extreme cross bite 5 years ago is now still a perfect smile all because I was under the caring hands of Dentist John and his extraordinary team throughout my Invisilign experience! Thank you again for being the most reliable dental teaming the Silicon Valley!!!

Joyce L. from San Leandro, CA (Source: Yelp)


Thanks Dr. Vellequette for making what had previously been so traumatic — not so anymore! So many good things have come from my visits. I truly appreciate Dr. Vellequette expertise and kindness. His cheery personality says it all. Just a few words to thank you and your team for their professionalism, dedication, care and enthusiasm during my visits. My Veneers look fantastic! -Joyce L.

Tuan D. from Campbell, CA (Source: Yelp)


This is it! My last stop for my dental needs. Every office I’ve visit so far had scared me. I was referred to Dr. Vellequtte’s office by a really close friend. The first time I came in for cleaning. Dr.Stephanie took care of me and was very gentle compared to the few places I’ve gone to the past few years. Dr. Vellequtte took a look around my mouth after the cleaning and notice that my bite was a bit off. I knew I needed braces but this was the first time ever that someone had put in the time to let me see exactly what was going on and how it can be adjusted. The associates recommended to have a session of whitning and change the fillings and I had agree to come back in to have it done. I had my damon braces on yesterday and I expected alot more pain than what it is. The waiting area makes you feel at home with comfortable furnitures with magazines that are always organized on the table. But one thing that caught my eye was the self serve refreshment counter that had bottle water and coffee. Highly Recommended!

Smita P. from Santa Clara, CA (Source: Yelp)


My husband and I have tried 2-3 dentists before we came to Dr. Vellequette. The things I love about this place: 1. They explain your insurance benefits to you and if you do not want out of pocket expenses, they always keep that in mind. 2. They are a friendly, efficient and caring staff who make a dentist appointment easy. 3. They are very happy to change appointments even at the last minute and accomodate you. This s our dentist for life.

Joseph S. from Belmont, CA (Source: Yelp)


I searched many dentists until finding Dr. Vellequette. He and is staff are very kind and professional people and worked with me as I went through orthodonics and used Dr. Vellequette for post orthodonic veneers. The venners look and feel great and receive many compliments. My experience has be great and always look forward to visiting his office. Further he is always looking to make the client experience better and bring the latest comfort and technology to his practice.

Emily F. from Sunnyvale, CA (Source: Yelp)


Many of us hate Dentist …Come on lets be realistic. I on the other hand always had the phobia for the dentist but Dr. Vellequette and his team seemed to ease that for me. the staff is great, Dr. Vellequette very informative and gentle. he educates you and explains in detail why and what needs to be. He helps you prioritize with the reason behind it. I highly recommend trying him. Thank you Dr. Vellequette and the team you guys are the best i finally found the one dental team i was looking for.

Me and my family have been coming here for 3 years. The staff has always remembered me and my whole family, by first name. They’re friendly and always efficient with my time. I’ve had great experience with every person I’ve ever dealt with there. We’ve had multiple cleanings, root canals, a few cavaties and even some teeth pulled! I recommend this office to anyone looking in the area.

Eddie Marie Harbin (Source: Google)


I have been a patient of Dr. Vellequette’s for many, many years. He is the best dentist in Silicon Valley and the staff is excellent. I have referred friends and business associates to him and am still getting thanked for the referrals. This office is state of the art and you will not be disappointed.

I had painful tooth issue which multiple other dentists could not fix during more than one year. In this dental clinic this issue was fixed in 5 minutes (bite adjustment) during consultation. Dentists here investigated my tooth much more precisely and noticed small overloaded area on tooth which I didn’t feel myself. 5 minutes work + 2 days relax and now I can eat everything again without pain. I have only positive experience, everything was great, doctor is nice and polite.

Cherry l. from Hayward, CA (Source: Yelp)


I highly recommend Dr. Vellequette if there were more stars, I’d add them! Dr. Vellequette is personable, professional and knowledgeable and has always taken care of me and my teeth. His staff are very professional and courteous! I live in the east bay so I travel to Silicon Valley twice a year or so to see Dr. Vellequette because he is that good. Best dentist I’ve ever had.

John K. from Sunnyvale, CA (Source: Yelp)


Dr. John and his staff are Absolutely Tremendous !   I have been to many dentists in the past 44 years . Some not too good, some great, but  now I have a dentist who is Awesome !  He does Beautiful work, explains what you need to know in a way that you can really understand it. I feel this pretty incredible energy just being at the office. I have never felt this way at a dental office. The entire staff is just so warm , friendly and  professional. I could not give Dr. John and his staff a higher enough rating.   5 Stars just does not suffice. My only concern now is that word is getting out how awesome Dr. John  is that I may have a harder time getting an appointment now !  He is in two simple words “The Best “

Lauren J. (Source: Zocdoc)


He was very professional, open, and welcoming. He didn’t hesitate to just come sit next to me in the waiting room and say hey. He looked over my teeth, told me I seemed like a good candidate for Invisalign, and then we went and did the requisite steps (making molds of my teeth, X-rays, etc.) Some of the mold gel slipped and ended up in my hair (my fault; I gagged on the mold), and he didn’t hesitate to work it out with a hot towel for me. The visit was pleasant from start to finish, and his assistants were also very nice.

I been coming to Smile Center Silicon Valley for fews years now and I have done many procedures from fillings to my first root canal and I can’t stress enough how the entire staff will go out of there way to accommodate to my needs and to make sure that every visit is a successful experience. Great customer service! My entire household is seen here but what stood out the most is how they conduct business. Their staff is well trained, the office culture is great, above all the honesty from all Doctors consultations is why they continue to earn my business and vote of confidence.

Carol C. from Sunnyvale, CA (Source: Yelp)


Dr. Vellequette, and his staff, are great — efficient, kind, professional, and personable. I love the way that Dr. Vellequette works with his staff. He is patient and seems to be interested in motivating and educating his team. Because of this I, especially, feel like I am in good hands. My smile is brighter, and whiter because of their sincere care in making me look my best while keeping my teeth healthy. Thank you so much

Kimberly M. from North Park, San Diego, CA (Source: Yelp)


Not sure where else you could go to get such excellent treatment! Dr. Vellequette is the most amazing, kind, professional and generous Dentist/ Doctor I’ve ever met! professional gentle handed and knows his stuff. The staff are highly professional and do great work. My favorite is Joni she’s the best!! she always takes good care of me. 🙂 Thank you Dr. Vellequette and staff for the unique and stellar experience! =D

Leo W. from Mountain View, CA (Source: Yelp)


I had an appointment with Dr. Vellequette this morning to get my teeth cleaned.  The dental technician also took x-rays.  After my teeth were cleaned, and I thought that person did a great job, Dr. Vellequette came in to discuss the x-rays and our game plan going forward to restore my teeth and smile on a long term basis.  We went over scenarios of the we work we can do, with a focus on what we should do.  His explanations were simple and straightforward and made it easier for me to understand. He concluded by giving the scenarios to his capable staff to research “pre-auth” with the insurance companies to get real numbers so I can make an informed decision. I felt very good about the cleaning and the consultation, and even got a humorous anecdote on my way out to lift my day.  Thank you Dr. Vellequette.  You and your staff are the best. I won’t try to name the gals and guy on your staff because if I leave someone out I’ll feel really bad.  That said, I highly recommend your services to everyone.  🙂

Peter K. from Sandown, NH (Source: Yelp)


Dr. Vellequette is a great dentist. I found Dr. Vellequette after I moved to the San Jose area in 2011, through a referral from a friend who actually interviewed a number of dentists before deciding which one she would go to. Thank goodness for her research! Her recommendation was spot on, and I highly recommend Dr. Vellequette to anyone who needs a new dentist. He works hard to minimize any discomfort, spends time making sure that you fully understand what is going to be done, and often shows you pics before and after to clarify what was done. Everyone at the office is friendly and helpful.

I’ve been a patient for two years now and I really view Smile Care as a group of friends. Every treatment or service I’ve had, has been with my comfort treated as a priority. It speaks well of Dr. Vellequette that all of the staff is so warm and pleasant. They all seem to truly enjoy working together. This is such a great office, the inviting decor, Netflix availability during treatment, the kind staff, flexible and accommodating scheduling all come together to create a stress free experience. I love this place.

This clinic has an awesome team ! Each person is equally efficient, and Dr. Vellequette cares to explain things in layman terms. Excellent service and very compassionate towards patients. This morning I completely forgot about my appointment, they called me up & managed to squeeze me into their busy schedule. They care !

Dion C. from Campbell, CA (Source: Yelp)


I been a patient of Dr. Vellequette and Dr. Fung for over 2 years now and I highly recommend their work, I would like endorse both doctors to anyone who in search of good dental office. The staff and both doctor ‘s stand by their work. I find Smile Center Silicon Valley an office that handle themselves with intregrity, honesty, and loyalty. These days is difficult to find good dental office, but I have done many procedure here from root canals to fillings and this office stands by their work. Nevermind disgruntled non-patient who is seeking to tarnish the reputation of this office.

Billy C. from Santa Clara, CA (Source: Yelp)


I hate going to the dentist. All the drilling, numbing shots, and uncomfortable xrays. Every office I’ve been to tries to overshadow this with delightful elevator music and bright walls. It’s not comforting! However, I was recommended to Dr. Vellequette and staff from a friend and I must say, my visits here have been nothing less than delightful. Dr. Vellequette and staff are so professional yet down to earth, they are just wonderful to work with. Up to date on all the current technological trends, they can help you with any of your dental needs. I’ve gotten my braces on from Dr. Vellequette back in December and I am loving the results so far. I originally wanted Invisalign (who doesn’t right??) however my current grill setup would not have worked with Invisalign so we opted for the traditional braces. I come in for teeth cleanings every few months and they do a wonderful, painless, job of it. Their hygienists are top-notch! As soon as these braces come off, I will have them do a whitening for me. I absolutely recommend Dr Vellequette and staff. Finally, I do not dread going to the dentist

Phil B. from Sunnyvale, CA (Source: Yelp)


My wife and I have been clients of Dr. Vellequette for almost 20 years and would consider no other. We are both ‘extra sensitive’ to pain and they are all sensitive to that. Further, Doc is a great one to discuss World Politics, Silicon Valley, Cars, and Family. Too bad we have to eventually shut up and get some work done. Both Doc and his wife are great people in addition to being simply the best in the business. Phil and Susan Brooks

I grew up having a horrible, sadistic dentist, and even though I’ve had a good dentist in the last year or so, I still have a lot of anxiety going to the dentist. It doesn’t help that I’m very prone to cavities. I switched to Dr. John Vellequette after my dentist Dr. Hong did not want to handle my dentist problems due to my anxiety with dental offices. Dr John Vellequette Office took me no matter what. It turned out that I need a lot of fillings. Needless to say, I switched. Dr. John Vellequette and his staff have consistently taken great care of me. If I’m nervous, he’ll take the time to talk me through my anxiety. He really cares about his patients and is great at getting you in quick if you are in an emergency. I recommend him to all my friends and neighbors. I highly recommend Dr. Vellequette if you are nervous at the dentist because he and his staff’s warm personality is greatly helping me overcome my fear of the dentist! I have finished many procedures without sedation and I’m glad his staff and the doctor cares about his clients. I just went in for a root canal because of took pain and he took care of him quick and I’m glad my family and I go to Dr. Vellequette Office.

Arachnophobia. Ophidiophobia. Acrophobia. Who gives a rat’s ass about phobia of spiders, snakes, and heights when dentists exist? Yes, I am unusually afraid of dentists, and I am not afraid to admit it. Imagine: little girl (me) who has insatiable desire for all things sweet goes to the dentist to get her first cavity fixed. She’s sitting in the waiting room and suddenly hears another young girl screaming her effing head off as she’s getting her cavity drilled. When it was her turn, what did they have to do to get her to sit still so they could do their drilling? That’s right, the dentist STRAPPED me into the dental chair so I COULD NOT move. Welcome dentophobia. I dread the dentist like Oprah dreads doing her taxes, which is where Dr. Vellequette’s office comes into play. They make sure I’m cavity free, give me a blanket and put on a DVD if I need to sit in that dental chair for more than 20 minutes (sans being strapped down), and don’t judge me when I grab all their complimentary disposable toothbrushes and chocolate chip granola bars. Their hygienist Mayr… well let’s just say the woman takes removing plaque and keeping your gums healthy serious. That pretty penny you pay for your dental insurance plan does not go to waste when you see this woman. while giving you all the numbing ointment your poor gums could ever desire. See Dr. Vellequette and get your grill in tiptop shape. If you’re into having teeth identical to Julia Roberts, I’m sure he could make it happen. (Note: you still won’t be her.)
