Always a positive experience. Solid staff. Carolyne is a great hygienist, thorough without pain, and very personable. No pressure to do any future services and they are conservative in recommendations. Dr Kovalchuk has a keen eye on recognizing the health of a tooth. I've had a few crowns there and the whole process is done in 1 appointment, no need to come back later. Lovely views of the water! read more

I love getting my oral health needs met here. Dr. Kovalchuk and the staff are very professional, yet genuinely warm and caring. They are sensitive to individual needs, the office is inviting and the views can't be beat! I always leave feeling extremely confident in the care I received and in my decision to bring my whole family over. I would not hesitate to recommend this office to anyone I care about. read more

I've been to a few dentist in Marin and have been unimpressed for one reason or another. Either they don't take insurance or if they do, their office is in shambles, the front desk person is rude or the Dr tries to upsell on procedures you don't need. Dr Kovalchuk is different. He was kind, considerate, listened to my problems and made time for me. His office views are unbeatable and his staff is the best in Marin. You're scheduled quickly and they actually call you when there's a cancellation. Everyone at this office is professional and kind. Dr. Kovalchuk is a game-changer for dental care in the Bay. read more

I am so happy they got rid of that assistant helper for the cleaning, she was rude and not very warm. Last visit I had it was a much nicer and gentle woman, and I am glad I do not have to look for another dentist because of the negative vibe of his assistant. They are busy so get your apt early! read more

Dr Kovalchuk and his team are exceptional, meticulous, professional and highly experienced. ! Best dentist for the entire family for both routine AND cosmetic work. I am a proud owner of 10 beautiful veneers that Dr Kovalchuk designed. He seamlessly took out the old ones and designed these beauties - see below. He also never told me I needed the old ones replaced, it was entirely my idea. Most comfortable no pressure experience entirely lead by the patient's wishes. The Dr was highly recommended to our family and we started with routine cleaning appointments, to which the Dr personally pops in to make sure the patient is perfectly happy. My husband, two children and I have now gotten our teeth cleaned, whitened and also had cosmetic procedures. Highly recommend this office! read more

After waiting 3/4 months for my appointment it was cancelled. Made another appointment 3/4 months out cancelled last minute again. Next appointment that works mutually is 6 months out. If it had just been handled a little more professionally I would not have written this review. read more

In the overall realm of dentistry I give Dr. Kovalchuk, his staff and the office the highest of marks; I'll start simply by saying to the trained eye (I do know Dentists) his office is well equipped with advanced 3D modeling software and 3-D dental printers and all the latest composites; gone are the days when you wander around for two weeks with a temp crown, it's all done within his office. Dr. Kovalchuk is thoroughly versed with these tools and moreover, he is insightful, caring, thorough and skilled at what seems like all aspects of dentistry. Despite all the latest equipment as well as the beautiful office view out to the water, his approach and rates remain reasonable given my previous experience at other MV offices. My only regret is that I didn't find his office sooner! read more

I love this dental office! The moment you walk in you can just feel the positive environment! Helen is sooo friendly and always takes the time to talk to me. She actually knows my name when I walk in! As for the doctor, Dr. Kovalchuk is great! Knowledgeable, professional, experienced and sooo caring. He thoroughly answers all the questions or concerns I always have. This place does everything to make your visit stress free. It may sound weird, but I do really look forward to my next dental appointment! read more

They don't get any better than Dr. Kovalchuk. Just last year I left another Marin County dentist that I'd been with for the past 20 years simply because Dr. Kovalchuk's new Mill Valley office happened to be much closer to my home than my former dentist's. However, over this past year, after having several cavities and bridges repaired as well as having had both my teeth and my gums cleaned, I've discovered that Dr. Kovalchuk is one of the best dentists that I've ever had in my life - and I'm a senior citizen going on 80 years old. Dr. Kovalchuk has most impressed me with his thoughtfulness in planning for my short and long term dental needs, as well as with his skills and care for my comfort when working on my teeth. Furthermore, he and his receptionist are pleasant people to work with. He offers free on site parking that is easily accessible from the freeway in a low rise office. And his own office unit is not only equipped with the latest dental technology, it offers a most beautiful and relaxing view of the lagoon. These are the reasons I too have given Dr. Kovalchuk a well deserved, five-star rating. - Dr. Hoag read more

I'm terrified of going to the Dentist and have had to have many crowns in my life due to grinding my teeth. I had a crown today with Dr. Kovalchuk, and it was simply the best dental experience I've had! He took great care to ensure I was comfortable and he was so efficient and precise in his expertise. The technology he used to create the crown allowed me to leave the office with the crown complete in one visit! The staff is wonderful, as well - his assistant is fantastic. Really outstanding practice, I highly recommend them. read more

Absolutely first class experience, for this new patient. Immaculate state of the art offices, a warm and courteous welcome from the lady on reception, chatted endlessly with Helen during x rays and cleaning, and Dr. K was super polite and professional. Wouldn't hesitate to recommend. 5 stars. read more

Dr Kovalchuk was kind enough to treat me in the middle of a Covid pandemic and I am highly appreciative. His protocol and actions made me feel comfortable and safe. His dentistry knowledge and his manual dexterity are superb. Combining this with a really nice human being makes me want to give him more than 5 stars but that's the upper limit. Thank you Dr Kovalchuk read more

I've been going to him for two years now and appreciate his approach to his work and that he always answers my questions thoroughly. His former receptionist is gone and his current staff are great. read more

Dr. Denys is probably the best dentist I've ever been to in my long years of dental work. He is very good at what he does. He is extremely thorough, very meticulous and the end result is the best it can be! I would recommend Dr. Kovalchuk to anyone needing dental services of any kind. Thank you for taking care of my needs, you are my dentist for life! read more

I am so grateful for Dr. Kovalchuk and his staff! Everyone is so kind, and Dr. Kovalchuk is an amazing general dentist as well as cosmetic dentist. He replaced my front teeth ~ which had sub-standard veneers on them for many years ~ with porcelain and they look absolutely incredible now + are very functional as well. read more

6 stars if I could. I'm terrified of the dentist. Left it 6 years between visits. Dr K is unbelievably kind, gentle and skilled. He began with some major cleaning, done in two long visits with not a moment of discomfort. With renewed confidence I signed up for him to finish an implant I'd started 6 years ago. My previous dentist (Evangelista in SF) wouldn't tell him or me the size of the device they'd used so he had to open up the gum, clear out 6 years worth of bone growth and experiment with various sizes and brands. He spent almost 2 hours getting the job done, as always he was incredibly skilled, kind and gentle. Two more easy visits to wrap it up and I find myself almost looking forwards to it, actually remove the almost, I am looking forward to it. Amazing dentist. read more

Again, another great experience! The level of care, skill and expertise is mind-blowing. And they utilize the latest technology. So grateful to have found them. There are so many dental offices that try to "up-sell" you on services one doesn't need. They don't do that here. They are honest and up front...always. Thank you again & again & again! read more

I highly recommend Denys Kovalchuk DDS. he does excelent work has good moral and ethic. The dentist is very honest on dental work that the patient needs. He is very gentle I can almost sleep thru the procedure and not feel any discomfort. The office staff goes the extra mile to make you feel welcome in the office. Everything is very clean and sterile. Elizabeth Anderson read more

I moved to Mill Valley recently, and was in search of a new dentist. Dr. Kovalchuk and his staff are great! I went 3 years since my last visit to a dentist. I'll admit, I was a bit nervous about returning. Dr. K, and his staff we extremely professional, and comforting.. I felt absolutely no discomfort during my cleaning. I can't wait to go back! read more

I mostly had a very positive experience here, but I'm not sure I'm going back. Which is such a shame as I was hoping I'd found 'my' dentist... Dr Kovalchuk is attentive, thorough, put my mind at ease and right on time. His assistant, Darlene is warm, kind and welcoming; she's super personable. These two get 5 stars. The receptionist gets 1 star. The only reason I didn't put up a 1 star review is because of everyone else in the office, plus the location, the feel, how well cared for the office is, easy parking, and that crazy awesome view :) Here's why the 1 star - when I'm asking questions about part of a legal document I'm signing that impacts my finances, I don't expect to be spoken to in a rude tone of voice while slowing-down-her-words and still not explaining clearly. While I was truly appreciative of the last minute appointment, even my initial call to the office was rushed and I felt like I shouldn't be asking the questions I was asking about billing, if my insurance would cover the services, and even finding the best time to come in. I felt pushed, to be honest a little bullied, and I may not return simply because of this front desk experience. Dr Kovalchuk did apologize and I had the utmost respect for him doing so. I believe that my concerns were addressed, and that's putting me more at ease. read more

I had the best cleaning of my life today from Allison at Dr. K's office. She was so thorough, educated me about my teeth, and informed me about new dental studies. Did you know you were supposed to floss before brushing? She was also so passionate about her career, her patients, and really did an amazing job. I look forward to seeing her again! read more

Wow. Just.... wow. I don't know what's more awesome: the location; the support staff (reception; nurse); the view ... I suppose it has to be the view. :) How many dentists' offices do you know of with a view overlooking a charming bay dotted with birds, the occasional seal, and with mountains in the background? That, and Dr Kovalchuk is supremely kind, personable, friendly, and immensely capable and professional. Some back story: I had been seeing the same dentist (Dr Dawn Stock, in Mill Valley) who recently retired, since my high school days. Although the doctor to whom she sold her practice is very very good, my insurance didn't do much with them so I was forced to finally look for a new dentist. My parents had been visiting Dr Kovalchuk for quite some time, and couldn't recommend him strongly enough. Suffice to say, I'm now getting my wife to switch dentists as well. He's that good. PRO: support staff, location, view, Dr Kovalchuk! CON: you will be torn between grabbing lunch next door at Robata Sushi & Grill or Piatti's Italian restaurant, while struggling to decide which new Ferrari model to buy at the adjacent Ferrari of San Francisco (yes, it's in Mill Valley, but called Ferrari of SF). read more

Ive been to many dentist over the years on the East Coast, I found Dr. Kovalchuck when I moved to Marin a couple years ago. I just completed my second crown with him. 2 down 2 to go. He is so advanced compared to any other dentist I've been to. He makes sure you understand your treatment plan, his recommendations He is not pushy at all, he leaves it up to you when you want to get started. In my case I had a crown done last year. I had another done today, and I have 2 more to go. I would never let another dentist do this kind of work to my teeth. I trust Dr. Kovalchuck completely. He is so skilled. Not only does he complete the crown in one appointment, It feels great afterwards. Unlike my dentistry in the past. I've had dentist before that have done awful work to my teeth, This dentist is a needle in a haystack, I'm serious. read more

We recently had to find a new dentist because our dentist of over 10 years botched 2 crowns. Enter Dr. Denys and his wonderful assistant Jo Jo. He fixed the problem and I got him to repair my front tooth which had a small chip. He did a fantastic job, my tooth looks beautiful but mostly no one would ever suspect that I had a repair, it looks so natural! The color matching is amazing. The Dr. has a beautiful relaxing conveniently located office, he has both great hands and is aware of the latest technology but his philosophy seems to be "do no harm". My husband has been going to dentists for 35 years. He unequivocally thinks Dr. Kovalchuck is the smartest, gentlest, most effective dentist he's ever been to. That makes Denys #1 out of a dozen. It's a relief to know that we have a dentist in Mill Valley we can go to and recommend with zero reservations. read more

A great dentist! My husband finally found a true professional to take care of his dental needs, and comes out of the office a very happy person. My personal experience has made me feel the same. read more

Outstanding work, trust, value, technologically up-to-date & friendliness are all aspects of an excellent dentistry practice. Dr. Kovalchuk has all these and more. He was straightforward about my treatment plan - not having gone to the dentist in 3 years. He was very accommodating, patient and knowledgable. On the day I was to get a crown, unexpectedly I had to watch my 4-week-old son, who came along right into the room to sleep in his car seat; and when he needed attention we took a small break. Dr Kovalchuk took it all in stride, a father himself, understanding and helpful - all with a slight, appropriate sense of humor. I remember him saying, as we neared a break and my son started to stir "If you are good Avery for a couple more minutes you will get a treat ... hmmm how about some milk." Plus he has an incredible imaging system and can build (sculpt) caps in the office in real time. I was amazed. He is humble and confident. His chair side technique was very professional yet friendly and re-assuring (I am a Doctor as well). When he showed me the images and allowed me to interact, prioritize and evaluate together the treatment plan - I felt included and important, yet trusted his judgment, of course. The outcome was outstanding. My teeth look and feel great. And his dental assistant Jo Jo - she too was of highest caliber and completed the picture for a great experience at the dentist (never thought I would say that). I do not always agree with the reviews on yelp, but these are spot on. Hard to believe but true. read more

Dr. Kovalchuk rocks! I am fairly demanding of service providers, I will admit. Dr. Kovalchuk and his team never cease to impress me each time I visit. His hygienist is top notch, providing excellent service from a position of knowledge and experience, always ensuring that we feel as comfortable as possible in what are often uncomfortable procedures. Dr. Kovalchuk recently replaced one of my crowns. By all accounts, my tooth was on the verge of needing to be pulled entirely. He did everything in his power to save it, avoiding a lengthy and costly process of installing an implant. Thankfully, he was able to install a beautiful crown on the existing tooth base using the latest technology of onsite (same day) porcelain crown production. I'm thrilled with the results. I highly recommend Dr. Kovalchuk and his team for any dental maintenance or repair services. read more

Dr. Kovalchuk is patient and careful with his patients. My teeth are in horrible shape due to poor choices made in my past, and Dr. Kovalchuk is kind and nonjudgmental. I've had horrible experiences with dentists in the past, and it has usually taken several appointments to build trust with the best ones. After only two appointments, I can honestly say that I trust his work, and that he truly has my best interest in mind when it comes to my dental health. Considering the area his office is located, I dreaded how expensive the work might have been. Not only is he reasonably priced, he was willing to work with me as far as payments go, being that my insurance isn't the best. At my first appointment, he didn't let my inability to pay for all that was needed keep me from getting the treatment that was best for me at the time. He didn't try to sell me work that didn't need to be done either, which is a huge plus in my book. He will have my business as long as I live in this area. Thanks, Doc, for being willing to work with a poor seminary student. You're a blessing. read more

Dr. Kovalchuk was able to fix a chipped front tooth when 3 dentists before him had failed. I am so grateful to him and his team and would highly recommend him. He also doesn't try to push extra cosmetic work on your which I am very thankful for. read more

This place is really different. All the hassles related to going to the dentist -they all went away. Dr Denys is THE BEST! He is so patient, explains everything when asked to, is gentle, funny, and non judgmental. You feel like you are seeing a friend (and his sidekick joe-joe is just that - a total kick!). In the past, I have always thought that I must have extra mouth sensitivity because I've always needed multiple pain shots before & even during a process. But not with Dr Denys. He takes his time and gets it all right the first time. Even the shot, I didn't feel it because he took his time waiting for the numbing agent to really kick in. Here are some of the other things I really love about my new dentist: 1. It's easy to make an appointment. And they have early evening appointments - so you don't need to miss work to go to the dentist. This makes them especially attractive in my book. 2.They called my insurance, did their research with them, and then worked out a way to lower my bill. Same work, lower bill. Nice. 3. The actual Dr is accessible to his patients. If you have an emergency, you can call his cell phone which he has listed on the voicemail. He also provides his email to clients so they can ask a quick question. I can't stand playing the telephone game - trying to explain to someone what I want them to tell my doctor. With a direct email, I don't have to. This makes them special, and very different. I just got out of having three old fillings drilled out, and filled back in - and it was so painless (emotionally, physically AND financially) that I had to write this review. Do yourself a favor and use Dr Denys Kovalchuk - you will be really glad that you did. read more

This place is a GEM! I went to several others in Marin, and thought my dental care was good until my first appointment with Dr. Kovalchuk. From the ease of making the first appointment, the location and clean, bright, attractive office setting, the warm welcome when my wife and I were greeted, the friendly office staff and how attentive, thorough and fast the dentist was, the entire visit was FANTASTIC. So happy I found them. read more

What other dentist gets so many 5-star reviews? I know what you're thinking. You're skeptical. Is this for real? These reviews must be fake, like those paid Amazon reviews. Or they were made by robots or written by people who inflate their ratings. Well, these ARE real, and the 5 stars is no inflation--Dr Kovalchuk and his staff deserve every star and then some. I love everyone in Dr. Kovalchuk's office! Kristen the office manager/receptionist is super personable and friendly. Ashley (dental hygienist) is sweet and knows her stuff, and Dr. Kovalchuk--well, what can I say that hasn't already been said? I came to him after not having seen a dentist in a few years (I know, I know) and turns out I had to have some dental work done--fillings and such. I hadn't gotten fillings in YEARS--like, I don't even remember the last time, maybe 15 years ago?--and was a bit nervous. OK, I was really nervous. But Dr. K and Ashley were super gentle. Zero pain. And my tooth-colored fillings look pretty amazing. Other perks: The music is great (Radiohead, LCD Soundsystem, and Peter Bjorn & John were playing to keep my toes tapping despite getting my teeth drilled on in the chair), the view is serene, and the plants (and the fish tank!) all around the office make this a calm and relaxing place. read more

Best Dentist ever... We just moved to the area and needed to get a check up / cleaning. Great people, great attitude and fun to be around. By far the best cleaning I have ever had... Thank you Dr. Kovalchuk!!! See you next time... : Cheers, Jason read more

Dr. Kovalchuk is very good and nice, but his receptionist is so rude & condescending... I arrived for my appointment and she just said that the hygienist didn't show up that day so no cleaning... kind of like is my problem now. Ahhhhhhh what if she could let the patients know in advance and not made us go all the way there. She is such a rude person!!! I'm shocked that she can get away with treating patients that way. read more

Not sure how to review a dentist, but thought he was honest and didn't push me to get unnecessary dental work done, and was very informative. I was even surprised he was the one who did the cleaning and not a dental hygienist. read more

Dr. Kovalchuk is an excellent dentist, as well as a kind and considerate man. I had a number of appointments with him, and his work was always thorough and painless. He has a very pleasant office, and the woman at the front desk was helpful and enjoyable to talk to. I highly recommend him to anyone seeking an outstanding dentist. read more

I'm very pleased with the professional care I've received from Dr. Kovalchuk and his assistant. For my first visit, I was seen by Dr. Kovalchuk on a short notice, which I really appreciated as I was new in the area and needed some quick fix before my trip. Today I had my teeth cleaned and I must say that I don't think I have had my teeth cleaned so thoroughly in many years, huge thanks to both Dr. Kovalchuk and Darlene! Also thank you for your kindness, for making me feel at ease, accommodating my sensitivity and providing some numbing! Like many people have said before, Dr. Kovalchuk is gentle, thorough and professional and I highly recommend him! read more

I'm #77 and as you can tell by the stars, thoroughly satisfied customer. I mean, look, this guy's got an impeccable manner, is very cool calm and collected, and on top of it all, get this, KNOWS HIS STUFF! There's a new front desk lady - Hellen - she's mui bueno - very kind and thorough.. If you value your mouth, go to this guy. Wanna have a "British" grill, go someplace else... nuff said. read more

Every time I've visited Denys office, I've had as pleasant an experience as one could have while at the dentist. From tooth extraction and deep cleaning, to X-rays and follow up visits, the entire team at Denys office were exceptional read more

Thank you Dr. Kovalchuk! I practically fall asleep in his chair, he's that gentle. His office is clean and aesthetically calm with simple air plants, and a stellar view of beautiful marshlands. I've been taking my son here for the past three years, and he agrees with me, Dr. Kovalchuk is the best! read more
