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.

I've been going here at least 5 years and it's always an organized and dare I say, pleasant experience. Every 6 months I'm here like clockwork, and I never dread it. Nice views as well. Now floss your teeth!

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.

Dr. Kovalchuk and Helen gave my cantankerous, demanding, rude mother the highest possible care with immense kindness and professionalism. Also, the view from the dentist’s chair is sublime.

My first appointment with Dr. Kovalchuk yesterday was a great experience. He is professional, kind and gentle. His office is taking great care to protect the patients and employees. I’m very happy with the experience and I’m happy to announce that I have a new dentist! 🦷

Upon arriving at the parking lot of the facility, you are instructed to text the front desk and let them know that you have arrived. After receiving the confirmation, you are instructed to proceed to the office.
All COVID-19 precautionary measures are in place at the front desk area. All staff is wearing masks. Only immediately served patients are allowed to be at the front desk area.
During my visit, I only interacted with the medical/dental staff. While all other rooms had patients being worked on, I was never in any proximity of them. I really liked the additional air filtration systems positioned

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

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

Our teenage son's orthodontist recommended that we see Dr. Kovalchuk to build up a baby canine tooth (he doesn't have a permanent tooth to replace it) so that his smile would look even. When our orthodontist called him a "bonding god," we figured it was hyperbole. But, after seeing the results, our orthodontist wasn't exaggerating! The tooth Dr. Kovalchuk made for him is indistinguishable from a real tooth! We couldn't stop smiling and remarking on how incredible it is. It was a real boost for my son's self image. Dr. Kovalchuk took time to evaluate him, used

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.

Dr Kovalchuk by far, best dentist I have ever found. Always for the patients, always gives you best advice and does wonderful job. My crown looks great she's works great. My fillings are still part of my teeth and not going anywhere any soon (unlike done by my prior dentist). He removed my wisdom teeth with no pain. Best "friend" dentist you can possibly get .

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.

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.

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

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.

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!

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!

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

I really can't begin to say enough nice things about Dr. Kovalchuk and his entire team! I live quite a distance from the office and yet I still choose to come here, because of the kindness & professionalism. I feel pretty darn lucky to have landed here.

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.

Excellent combination of friendly, smart and very good dentist. Staff is nice and professional. Location on the lagoon is a great view during your visit. 1st class office. None of the mill valley attitude you can get around here.

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

Dr. Kovalchuk recently took over this practice from my prior dentist. I was impressed by his professionalism, knowledge, and warm demeanor. He was able to discern the source of my issue within a few minutes and was very considerate towards me during the treatment process ( ..I'm not a big fan of dental drills). The assistant was also very sweet and gave me some lip balm when my lips got dry :) Very happy to have him in this location. Same great bay view!!
