Julius G. from Auburn, WA (Source: Yelp)


Before I give my review, I have to disclose that I’m obsessive when it comes to getting the look and feel right of everything. My wife, unfortunately, can attest to this. After having broke my front tooth off at a famous amusement park in California, I began my quest to find the best person to replace it with an implant. After an exhaustive online search, I found Dr. Dean Kois. I chose him based on his glowing peer and patient reviews. He stood out for his eye for quality and his determination to give his patients the best smile they can attain. Mind you, I live an hour south of his practice, but I figured if I wanted to get the best result, I needed to travel to see the best person for the job. With out a doubt, I made the right choice. His eye for perfection showed when on the first try, he didn’t feel ‘right’ about the color match. We attempted twice to get it it perfect, and perfect it is. Believe me, coming from this obsessive man, this is a big deal. I couldn’t be happier with how beautiful the result is and I can’t wait to get home to show my 3 year old, who has continually asked these past months, “Papa, where is your tooth?” If you want the best results, you have to get Dr. Dean Kois to help you achieve them. Everyone on his staff, from his front office to the back office (Sarah, Michelle and others) are professional, friendly and achieve a high level of customer experience. Don’t hesitate, go! Julius.

I moved here from a very small town in the Midwest. My dentist there had trained at Kois Center and referred me. He was a good dentist, but limited in what he could do, being in a very small town. I was absolutely amazed by the technology employed at Kois Dentistry. After my initial consult, I remarked, “I do believe I have never had a more thorough understanding of what is going on in my mouth.”…and I’m almost 60 and have been pretty careful about my oral health. It was just an outstanding experience and the follow on care has been superb. Great staff, great facility, and great service.

Dr. Dean and his staff have made me feel extremely comfortable from day 1. He is more than willing to explain exactly what your dental condition is, and he is able to explain it in layman’s terms quite well. Furthermore, the regular treatments seem to have done more for my dental health than years at my previous dentist’s, and I actually feel great when I leave! I thank Dr. Dean and all the staff at Kois Dentistry for their excellent work.

Scott B. from Seattle, WA (Source: Yelp)


Hate going to the dentist and always have. The entire practice, which is a family business, works to whatever your needs are. They’re industry leaders and pioneers to a number of procedures and innovating, game changing tools and technologies. I have had check ups, gum grafts and a chipped tooth fixed. Interestingly enough, with the chipped tooth, I had had two previous dentists attempt to fix this, only to the have the filling come out weeks later. I have had the installed by Dr. Kois for a year now. I can recommend this practice without reservation. The Center is located on the shores of South Lake Union, beautiful and a great excuse to have a good lunch after getting your teeth cleaned. Anything you could potentially need done to your teeth save braces can be done here. Oh, and the people are funny.

Before I went to Kois Dentistry it had been 2 years since I had seen a dentist. I had a lot of anxiety about finding and seeing a new dentist. For my age, I’ve had a good amount of work done on my teeth. I was very, very nervous as I had no idea if I needed more work done to fix any issues (a previous dentist did a poor job on one of my crowns). I just had my first visit and looking back on it, there was nothing to be worried about. Everyone at Kois Dentistry is amazing. They made me feel relaxed and none of them were judgmental. Dr. Dean Kois thoroughly examined every inch of my mouth and it turned out my teeth were in great shape…I just needed a cleaning. It put my craziness at ease and was one of the nicest Dr.’s I’ve ever encountered. If you’re scared about going to the dentist or just need a new Dr., don’t hesitate…give Kois Dentistry a call. They’re amazing and I’m so glad I found them.

Chunky Q. from Seattle, WA (Source: Yelp)


Following an accident, our family dentist strongly recommended Dr. Kois for prosthodontic work. Our dentist commented that he had had seen Dr. Kois’ work and that he held Dr. Kois in high regard. I’m thankful for the recommendation and that we followed through. Every point of contact with this practice has been exceptional. I sent my first inquiry via email and received a prompt, professional, and genuinely useful response. The follow-up phone call with Stacy at the front desk was equally impressive. She was highly empathetic, personable, and professional. I can’t think of another minor phone conversation that left me with such a strong positive impression. The day of our appointment continued the trend. After being warmly greeted we were seen at the scheduled time. The facilities were immaculate and stylish. I’ve never been in such a beautiful dental clinic before. The dental assistant was friendly and inviting and Dr. Kois himself left a remarkably great impression. After a brief introduction, he listened carefully to our concerns, performed a thorough exam, and discussed our options. Everything about our interaction epitomized a patient centric approach to his practice. Any one of these interactions would have left a good impression, but to have them all with one practice is nothing short of amazing. I can’t recommend Kois Dentistry highly enough.

Accutint B. from Bellevue, WA (Source: Yelp)


Since 2014, Dr. Kois and the Kois Dentistry staff have provided me and my wife superb dental care and counsel. We’d been well served over the prior 40 years by a wonderful dentist and his staff. And when he retired we were apprehensive about finding a new dental practice that could deliver excellent professional service and counsel in a manner that was comfortable to us. We got lucky! On a referral from an out of state friend, we contacted Dean and his staff. We had our first consult, exam and cleaning and, well, we never looked any further. Since then, we have received routine dental care and replacement crowns. Terrific results. Final note: talk about a state of the art facility, Kois Dentistry should be a poster child!

I’ve been a patient with Dr. Dean and Tara Kois for over 5 years now and have nothing but rave reviews for them and their staff. They honestly take their time in getting to know their patients, which just goes to show how caring they all are and the type of calming environment that they try to give their patients. I have recommended them to all my friends, family and coworkers who are shopping around for a new dentist!

I was referred to Koi Dentistry by two dentists (one teaches at UW) , both retired not, as one of the best dentists in the State of Washington. Dr. Dean (Prosthodontist) and Dr Roloff (Orthodontist) aren’t just great dentist but also great people, and so is their staff. They are always super nice and friendly. Dr. Dean is one of the best dentists in town. He did the PAOO (Periodontally accelerated osteogenic orthodontics) surgery on me before I started Invisalign with Dr. Roloff. Not the prettiest surgery out there but I completely trusted them. Dr.Roloff gave me a lot of confidence and I couldn’t say no. So glad I did it. My mouth healed perfectly over the next few weeks and thanks to the surgery the invisalign process is going extremely well. Dr. Roloff does an amazing job at tracking the movement progress and keeping the patient informed at all times (I tend to ask a lot of questions). I’ve email her a number of times with questions and she has always responded back within 24 hours. I have never had any issues scheduling appointments of any type and they are always super flexible with times. I really like the email and text reminder notifications previous to any appointment. My hygienist, Dana, she is amazing at her job. Their equipment is the latest and greatest and so is their office, super welcoming and friendly. I would absolutely recommend Koi Dentistry to all my friends, family and anyone who reads this review.

Tim P. from Seattle, WA (Source: Yelp)


Dr. Kois does everything you’d expect from your dentist, but also so much more. Since I switched jobs about three years ago, I had not been very good about finding a new dentist. I found Dr. Kois through a friend but was still apprehensive about going in, as past dentists have been quick to tell me about all of the things wrong with my mouth. That wasn’t the case at all with Dr. Kois and his staff – they were able to get me in quickly, took good care of me, and didn’t try in any way to nickel and dime me for excessive treatments. They made it clear they care about my well being and clearly explained the treatment plan they thought made the most sense moving forward. What really sold me on Dr. Kois, however, was his willingness to accept an emergency weekend appointment after only seeing me one time. He picked up my call Sunday morning and was in his office just a couple of hours later to help me out. As long as I’m a Seattle resident, I’ll be seeing Dr. Kois for my dental needs.

W. S. from Seattle, WA (Source: Yelp)


I just left the dentist and while I was sitting in the chair I was thinking to myself about how long I’ve been seeing Dr. Dean and how awesome he is and that I should write a yelp review, I’m not one to write many reviews but they deserve it. I have been to many dentists trying to find “the one” and was lucky enough to have Dr. Kois recommended to me. I love them all there! Dr. Dean has a great sense of humor, great “chair side manner”, does an amazing job and has NEVER made me feel bad about the condition my mouth was in when I first started seeing him. It always makes me feel good to hear positive comments between doctor and assistant while they are working on my mouth. I grew up with not so great dental habits and poor dental work that was disastrous for the long term. Dr. Dean has been working with me for a few years to correct the damage and always at my pace. I can’t recommend them enough they are that amazing. And this wouldn’t be a complete review if I didn’t mention Dana my hygienist, she is amazing too. So sweet, gentle, caring, and funny. I actually look forward to my cleanings!

I have been going to Kois Dentistry / Kois Centre for the last two+ years since I have been living in Seattle and I absolutely love this office and everyone who works there! I have, and continuously, refer my colleagues, friends, and family to this practice because of their friendly staff, hospitable service and incredible knowledge. Not only are Dr. Dean and Dr. Tara extremely knowledgeable but the rest of their staff at the Centre are just as knowledgeable as them. My favourite hygienist is Dana! Every time I walk in for an appointment, she greets me just like a friend rather than just as another patient. I would absolutely recommend this dentist to anyone in the city of Seattle. Check them out, you will not be disappointed one bit.

Heather A. from Moses Lake, WA (Source: Yelp)


I have been a client of Tara and Dean Kois for years! I have always been anxious at the dentist, and have had a lot of work done over the years. Seeing Dr Dean Kois has been a great experience, not only has he calmed my nerves, but he has given me a great smile and confidence about my teeth! I would recommend them hands down as the best dentists in all of Seattle!

Stephanie P. from Seattle, WA (Source: Yelp)


Dr. Kois and his team have been my ‘go to’ for dental care for the past 3+ years. This group’s exceptional attention to detail and a warm and caring atmosphere definitely make going to the dentist something to look forward to! This group also has a wealth of knowledge when it comes to preventative and restorative care- I never leave an appointment without a plan or a question unanswered.

I highly recommend Kois Dentistry! I have been a patient for over 6 years, and I am always impressed with their quality, friendliness, and professionalism. They truly are a family operation, which is something you don’t see too often these days. They always greet me with a smile and recall small details on my life, such as where I was going on vacation. It’s nice to receive this kind of treatment from your dentist, rather than feeling like you’re just a chart or a number!

Victor Diaz (Source: Google)


First I would like to say that this is the nicest dental facility that I have ever stepped foot into. Although location and appearances play a factor into experience, it was the whole team at Kois Dentistry that really deserves the 5 star rating. The moment you walk through the doors you are greeted by the most friendly and a respectful staff. Even more so than how they treated me, there was an elderly women and her daughter at the front desk while I was waiting to be taken back, they seemed to go above and beyond to treat them with care and dignity that speaks highly of the team they have at this dentistry. Once taken back, I was in awe of how state of the art everything seemed to be. I couldn’t recommend this place enough to anyone who would ask!!

Lindsey Leano (Source: Google)


My husband and I have been going to the Kois office for over 2 years, and we love their practice so much. They are always professional, very friendly, fast and trustworthy. They also have deep knowledge of the industry including restorative dental care. I always feel like I get a straightforward answer and that I’m only being recommended services I need. My primary dentist is Dr. Tara Kois- she’s so great, really listens to my concerns. I’ve met Dr. Dean Kois once and he was very personable and didn’t try to sell me something I didn’t need. I trust this office and always recommend this practice when asked for a great dentist! My dad was a dentist, so I know what to look for when searching for a great one!

Paul M. from Castle Hills, Lewisville, TX (Source: Yelp)


Dr. Dean and the Kois Dentistry team provided me with outstanding dental care and advice. I suffered a stroke in April. During the incident i fell, dislodging one of my front teeth. My teeth and entire mouth were hyper-sensitive as a result. A teeth cleaning sounded painful much less being fitted for a partial to wear while I became stronger for dental implant. Dr. Dean and his staff took excellent care of me. Could not have been more happy with their care.

Sheri Greaves (Source: Google)


I would never have thought I would ever say that having a crown done was a pleasant experience, but it actually was…:) I hadn’t had one since the day when it took 2 hours of drilling and the temporary crown on and off 15 times, and all of that, but this took almost no time at all, there was no pain at all…Dr. Kois is so nice and so gentle, and understanding of the “dentist-phobia” that I have…:) I won’t wait so long to have the next one done. Thank you!!

A great friendly dentist I would recommend to anyone. Being part of the clipper round the world Yacht race and not seen a dentist in 10month I started to have sensitivity in a tooth and though I may need a filling. Recommend by fellow crew member local to Seattle, I went to have my teeth check over, they gave me a thorough checkover and X-ray, put florid on my teeth and resurged me there was no need for a feeling.

I have had nothing but amazing experiences at Kois Dentistry. Everyone at this office, from the front staff to the hygienists to the dentists are excellent providers and wonderful people. I have had excellent care from Dr. Tara and Dr. Dean Kois and I would recommend them to anyone. I trust them and I value their expertise and experience. Kois Dentistry is an excellent choice for anyone in the Seattle area and beyond looking for great care that they can trust.

Steve R. from Seattle, WA (Source: Yelp)


Dr. Kois and Dr. Kois! They are absolutely the best! The staff here works in great harmony. Everyone is friendly – you are always greeted with a smile and kind words. The office itself is magnificent. Modern and spotless. And of course what really matters is the quality of care – and that is tops. Dr. Dean and Dr. Tara are top dentists who take enormous pride in their work – and in being there for their patients. They are natural care givers. And Dana, their hygienist, takes her cues from them – she is a perfectionist – and somehow gets your cleaning done with no discomfort. Just big smiles all around.

Jeffrey W. from Seattle, WA (Source: Yelp)


Due to multiple complications caused by a previous Edmonds dentist in 2016, I’ve searched and consulted 9 dentists/ prosthodontists over 9 months across the greater Seattle area and out of state. I was told by many of these dentists that Seattle has one of the best dental care professionals in the nation. But repeatedly, these top dentists have backed down on my case (after taking my money) and told me there is nothing they can do to help me but to accept life. Over one breakfast, my teeth were acting up again. I searched frivolously on the ‘net for yet more dentists to see if there is anyone else I haven’t visited. I don’t remember how I came across the Kois Dentistry in Seattle’s South Lake Union district, but I decided to phone in just to chat about my situation. From the first moment I spoke to receptionist Su, she provided the utmost attention-to-detail responses to my inquiries, and was able to set up an appointment to see Dr. Dean Kois within the week. Having been deeply depressed over my unfixable teeth for so many months, I managed to drag myself into Kois Dentistry, repeating the by-now fluid process of filling out paperworks and go through explaining my problems with the dental assistant, Michelle. Then enters Dr. Dean Kois. Right from the get go I noticed Dr. Dean is a lefty, just like me. Perhaps lefties think alike, I felt an immediate connection to this friendly and humorous man. Dr. Dean not only understood every bit of my concerns, his responses and diagnosis were spot on in pinpointing the false works and undiagnosable symptoms which the previous 8 dentists turned me away for. Even though at the time I have completely lost faith in all dentists and their untrustworthy practices, Dr. Dean managed to bring me out from the bottom of the well, and patiently laid out clear plans to help solve all my dental problems. Over the course of one month, I visited Dr. Dean every week to slowly and meticulously fix previous mistakes put in by the other dentist. I was amazed by the feathery touch, quick and confident hands, and at times, much needed reassurances Dr. Dean provided. While he is great at turning sour experiences into lighthearted jokes, as soon as a serious inquiry is asked, he would address the concerns in the most professional and in-depth manner. In the end, Dr. Dean gave my life back after 9 dark months. I’m very grateful to have come across the Kois Dentistry, and is delighted to have Dr. Dean as my permanent dentist in Seattle.

Pauland Christine M. from Seattle, WA (Source: Yelp)


We have been going to Kois Dentistry for almost 10 yr. and love them. Both Tara and Dean are top notch dentists and so very nice. They have taken great care of both of us over the years and have even come in for emergency appointments when needed. They also have such nice people working for them. We feel very well taken care of every time we go there and actually look forward to our visits. Very thankful we found them.

David M. from Bellevue, WA (Source: Yelp)


Fantastic Dental practice! Dana cleaned my teeth this week and was nothing short of phenomenal. Gentle, thorough with an endearing chair-side manner. Dr. Dean and his team are currently working on a long-term treatment plan to repair a front tooth with a dental implant. His plan is well conceived and sensitive to replacing missing teeth. I could not recommend. Kois Dentistry with any higher distinction.

Destiny C. from Seattle, WA (Source: Yelp)


I am still sitting in their lobby waiting for my ride post op but I couldn’t wait to post a review. I was referred to this clinic by two friends of mine who work for the teaching center associated with this clinic. After breaking my perfectly healthy tooth on a piece of pizza several surgeons refused to do the impant surgery because of the location of my sinus nerve. I met with Dr. Dean Kois and he instantly made me feel at ease. He told me I was a candidate for surgery and I scheduled my appointment several months out. I work in healthcare so I hold the practitioners and practices I seek care at to very high standards. This clinic exceeded my expectations. Stacey at the front desk/ financial department is one of a kind. She is genuine, knowledgeable, considerate and really helps you feel at ease when scheduling, making payments and planning future care. I was told the surgery would take about an hour. My boyfriend dropped me off to go get his teeth cleaned down the road. My “complicated” surgery took him less than 30 min! Faster than it took my boyfriend to get his teeth cleaned. Getting oral surgery is not fun at all, but I wouldn’t think twice about doing it over again if Dr. Kois was preforming the surgery. Becki his assistant was top notch. I had a panic attack before showing up because surgery is scary! No matter how routine. She had the most amazing bed side manor, answered all of my questions and really helped me get comfortable pre and post op. They are an incredible team. Overall this is the best experience I have ever had at a dental clinic. So much so that I am going to have them place my crown rather than my normal dentist. I’m even going to fully transfer all my care here for routine cleaning and visits. I really love my old dentist, but I am confident there isn’t any other dentist that comes close to the experience and service they offer here. I am so thankful and so appreciative I found this place. A true gem in the city. If you are are in need of a dentist or oral surgeon do not hesitate calling them! They will help you understand your insurance benefits and will work with you on payment. You have nothing to lose! Go perfect your smile with Dr. Kois!

Meryl M. from Seattle, WA (Source: Yelp)


Dr. Dean and Dr. Tara are the best! I came to them years ago after a rather traumatic filling at another dentist, and they have been wonderful to me ever since. Dr. Dean has reassured me through every little filling, and Dana is probably the sweetest and most gentle hygienist ever. I will never leave these guys and I super appreciate everything they’ve done for me and my pearly whites!

Margery P. (Source: Google)


Kois Dentistry is the most professional yet friendly office I have ever been to. They are prompt and very customer oriented. They are sensitive to patient needs and preferences, and go out of their way to make patients comfortable. Dr. Dean is highly skilled and well respected by his colleagues, and is a bit of a perfectionist – a great trait in a dentist! And his implants are excellent! I have been going to Kois Dentistry for about 10 years and have been totally satisfied and impressed. And Dana, the dental hygienist, is the best! Thorough and patient and considerate. They have an excellent team!

Osama K. from Seattle, WA (Source: Yelp)


Kois Dentistry is a top notch facility with dentists who are a cut above the rest. Dr. Kois has helped me on multiple occasions, and I felt that his level of knowledge, care, and service were so good that I sent my father to go see him with a difficult scenario. The entire office is full of people who really love what they do, and it shows in the care and consultation they provide to their patients. I recently had a tooth chipped, and even during his time off, Dr. Kois was generous enough to make time for me to come in and get it fixed. Not only that, but his detailed work was so amazing I cannot even see where the chip was! If you are in search of a great dentist(s) in Seattle, with fantastic care and service, there’s no better place to go.

Rusty F. from Seattle, WA (Source: Yelp)


Have been a patient for a year now. A great experience. Very friendly staff from dentist to assistants all the way to reception . They get you in on time and make you feel as a new friend. Doctor Dean Kois explains all procedures and doesn’t pressure you to do something your not comfortable with. Very clean and comfortable surroundings. Can’t say enough. Rusty Flook.

Galina Pogosov (Source: Google)


I had my first (new patient) exam today after a long time of no dental care. I was embarrassed and terrified of what they were going to say and find. Not only did the dentist and his assistant put me at ease but they even managed to pay a few compliments about my teeth. The office is very high tech but very personable. Dr.Dean was easy to talk to and answered all of my questions–I did not feel rushed. Dana the hygienist was amazing. My husband and I are both (will be) happy returning patients.

Phillip G. (Source: Google)


I have been going to Kois Dentistry for close to 4 years now and have never felt more comfortable at a dental office. They provide exceptional customer service as well around the clock dental care! From Dr. Dean, Dr. Tera, Dr. Bree to Michelle, Dana and Terri, the staff here is outstanding and extremely knowledgeable. All the equipment they use here is brand new and top of the line. I have never been to a dental office and felt more welcome! I have referred all my friends and family to Kois Dentistry and will continue to do so. Undoubtedly the best choice I have made was coming to here for all my dental needs! Please give them a visit if you are searching for a new dentist and you will not be disappointed! To EVERYONE at Kois Dentistry, thank you for always taking care of me and my family!

Scott M. from Seattle, WA (Source: Yelp)


I’m 64 years old. I recently had a dental implant done by Dr. Kois on an upper front tooth. He did an excellent job. He is very knowledgeable and very professional. During the course of this procedure I was always confident that I was in the hands of an expert. He and his staff are very friendly, courteous and helpful. I recommend him highly.

Rachel S. from Seattle, WA (Source: Yelp)


As someone who suffers from slight dental anxiety, I can say with ease Dr. Kois will be my dentist for as long as I’m in the Seattle area. He is friendly, informative, and gentle in his approach. I required an emergency repair on a chipped tooth and he was willing to meet me out of hours to fix me up! I am so grateful he cares so much for both new and long-time patients! After a speedy repair, my teeth look absolutely perfect. He provided me with additional context about what next steps to take along with future dental care, and I’m very much looking forward to working with him in the future. Seriously – come see this guy!!
