I had a wonderful experience considering the circumstances. I came to bring my daughter for graduate school. I had an unbearable toothache I could barely talk or bite down. I googled dentist in the area since I had never been to California and didn’t know anyone to get a referral. I found Dr. Ko. He took X-rays, diagnosed me and attempted to send me to an oral surgeon for an emergency extraction. No one was available for weeks. Being sensitive to my pain and what I was going through he made a decision to do the extraction himself even though he stated he no longer does extractions. I was elated and so grateful. A few hours later the tooth was removed, the pain relieved and I was able to eat and be productive for the rest of my trip. The customer service was excellent from the receptionist helping to take my mind off the pain by telling places to go and things to do to Dr. Ko! I definitely recommend this place not just a dentist office but people who care!!

The entire practice is amazing! From the 1st contact with Esther, such amazing person to work with. The staff including Kimmie are very professional, thorough and just a pleasure and enjoyable dental experience! Right?!? Amazing dental experience is what you will get here. Dr Ko will show you all the places on your teeth that need action. He actually has a video wand that takes still pictures! He's awesome! You will never regret seeing Dr. Ko for your dental needs. Thanks team!!!

This was my first time here, but everyone was friendly, helpful, and professional. They went out of their way to really make me feel at ease. They follow...
More
Have been a patient for. 20+ years and have never had a bad experience. Both Dr. Ko and Maria are very kind and gentle as well as thorough in their work and very skilled. Highly recommend.

I’ve been going to this dentist office since 2009. Retired from work in 2017 and moved 3 hours from Pleasanton. I still make the trek twice a year because they are the best!
More
We arrived here because the previous dentists we had delivered poor quality of work. So far, after one visit I can tell you that they are all VERY nice people; they were attentive and very thorough— looking at all previous work done and noting any problem areas, while being thoughtful in their delivery. The cleaning was very thorough and done by Maria who is extremely gentle and kind. My 85 year old mother gave me the recommendation for him so I knew Dr Ko was a nice man with a nice manner, haha... and he is! I was a nervous wreck going in and everyone went out of their way to support me. Thank you so much!
More
Love everyone in this practice! They treat me and my family with very personalized care
More
Dr. Ko is without a doubt THE MOST Professional, talented, caring dentist I’ve ever been treated by. And at 61 years of age, I’ve been to a few. If you truly want ‘THE BEST’ advice, treatment, friendly bedside mannered dental experience at the fairest rate you can find, come and experience what I’ve enjoyed here at Dr. Ko’s, from him and his entire staff, for over six years now. Sincerely, Michael Hyczar

Love this team of professionals.
More
I wish I could give a much higher rating than just 5 stars... I've been seeing Dr. Ko for a couple years now and couldn't be happier. Dr. Ko and his team provide the best dental care I've ever had. They are all very skilled, provide great explanations/recommendations, and are focused on ensuring you have a comfortable and no-stress experience. I've never had even the slightest pain from any procedure (including fillings and cleanings - and you know how much they can hurt if done roughly or too rushed). Esther, who manages scheduling, is so kind, responsive and helpful, particularly when an unplanned appointment is needed. Thank you all!!
More
Very nice office staff and dental staff. Efficient and relaxing. Also gentle. Thank you Dr Ko and your staff!

I am 100% satisfied with the care I had at Dr John Ko's office. Dr. Ko and his staff are extremely attentive, professional and COVID sanitary/safe.

I got a filling after a root canal and it only took 30 minutes! Denise, Kathy and Dr. Ko were super nice and professional as always! I always have a great experience at Dr. Ko's office!
More
Very friendly and helpful staff.  Was able to schedule a next-day appointment at a convenient time.  Very informative meeting with Dr. Ko about my teeth and needs; he took the time to explain everything and show me certain things using a live magnifying camera and big screen.  And then an extremely thorough yet gentle cleaning; no pain during, nor any sensitivity afterwards!Adding to my first review:  Just had two fillings done (cavities discovered during initial appointment.). Went very smoothly and 100% pain free.  Great doctor and staff!
More
I'm always looking forward to seeing all DrKo staff.I receive polite quality encouragement to care for my oral health Thanks to all Mr Jay Bowman.
More
Always the best!

This place gets 5 stars! I had neglected going to the dentist for years because I really don't like the dentist. Recently, a friend of mine referred Dr. Ko to me and only said great things about him and his staff. I decided to give him a try and was so impressed with Dr. Kon and his staff- they are all so professional, kind and caring.  Esther is the best receptionist, so helpful and friendly! Dr. Ko's assistant (sorry, blanking on her name) is so sweet and lovely, Maria is the best hygienist and Dr. Kon is just the best dentist! They have completely turned around my negative association I had with visiting the dentist to a positive one. Now I look forward to having all my dental check-ups and cleanings done here and will highly recommend to anyone looking for a dentist in the East Bay!
More
I was able to book an appointment online and the next day received a call from Esther assisting me with any questions.Dr. Ko and team were able to accommodate me urgently and address my needs. Dr. Ko is very thorough and compassionate for his patients, you can tell in the way he presents himself!I have more upcoming appointments scheduled with him and compared to all the dentists I have ever been to I am highly impressed and will for sure stick with him and his awesome team!
More
Thoughtful personalized care. Wonderful staff.

More
Awesome visit as always, great staff and they keep me updated on what I need to do to keep my teeth clean and shiny :)
More
I am so glad I found Dr. Ko, aside from being an excellent dentist, he is very gentle and kind. I found him by pure serendipity, I got off at the wrong floor and saw Dr. Ko's office. I've been wanting to change the cap on one of my front teeth for years, so I took a picture of the sign on his front door and then googled him a few days later. I was impressed by his excellent reviews so next time I was in the vicinity I stopped by and made an appointment. I was immediately impressed by his professionalism and the way he explained my options. I proceeded to get my cap replaced and am so happy with the results. During the procedure, Dr. Ko explained what he was doing every step of the way. This made for a very good experience. I have decided to make Dr. Ko practice my new regular stop for teeth cleaning and dental check-ups.
More
Dr. Ko is so kind, patient, and caring and will totally put you at ease. His staff is fantastic as well- Maria is so compassionate and sweet and does a fantastic job making you feel comfortable getting your teeth cleaned. I highly recommend- especially if you have any type of dental fears- they will take excellent care of you!
More
Very good experience all the way from front desk to Doctor Ko .
More
Dr. Ko was very thorough in his explanation of what was to transpire and he continually checked to ensure I was comfortable along the way.
More
I chipped a tooth and called his office on a Friday night and they had me in on Monday to take care of the tooth. Dr Ko does great work, is very kind and he understands that most people do not like going to the dentist so he takes the extra steps to make sure you are as comfortable as he and his staff can make you.If you are looking for a dentist that cares about you and a dentist that will keep your teeth healthy and looking good, I am sure you will find Dr. Ko and his staff to be what you are and have been looking for.

Dr. Ko and his staff are the greatest. They are very professional. Dr. Ko never suggests or does unnecessary work. Something might become an issue with your teeth in the future, and he tells you so. Just keeps a close eye on things. Great personality, he and the whole staff put you at ease. Have to praise Maria, the hygienist. Never had a better cleaning. Very gentle touch. Esther and Linda thank you for everything. (Linda, I hope I got your name right. I apologize if I am wrong.)Go see Dr. Ko. We live near Fremont, CA, and drive up to Pleasanton (about a 45 minute drive) because Dr. Ko and staff are that good.Jacquie & Manuel Sousa

I was with my prior dentist for decades and was apprehensive about the change to a new dentist. My expectations were exceeded and I am delighted with every aspect of my new dental office.
More
As always the cleaning was so gentle I fell asleep during it and didn't wake up until we were done. Can't ask for more than that! Continues to be the best dentist office I've ever worked with.

Dr. Ko and the entire team were superb and awesome as always.
More
I am a big fan

I will highly recommend this place.

Great dentist and great staff that make you feel at ease regardless of whether it’s a check-up, cleaning, crown, or major/multiple procedures. I finally have healthy teeth and gums because of them!
More
Maria, my hygienist, is truly the sweets most caring person ever. I tend to chat a lot but today I was crunched for time so she worked quickly to help expedite my visit. You're the best!
More
Great!
More
As always, everyone was so kind to me. I know I am a pain, since I am so nervous all the time, but I am always made to feel much bettter by everyone's kindness. I am hoping some day to have all my teeth fixed up!
More
Office is always clean and welcoming with staff that want you to feel comfortable.

Dr. Ko and his friendly staff always makes my visit to his office a pleasant trip.He is calm, congenial, and is an extremely talented dentist. My wife and I have been enjoying his service for years, and are very happy with him.
More
Best dental office ever! The staff are all amazing and take time with each patient to make sure all their needs are met and that you understand all your options. They dealt with the major anxiety that I originally came in with with kid gloves which made me more comfortable with every visit. They treat you like family and I actually look forward to going to the dentist for the 1st time!
More
Friendly greeting as soon as I walked in, my appointment started on time, and Maria, the dental hygienist, was the absolute best. So glad we found this dental office last year. Crown work Dr. Ko did for us was excellent...simply amazing. Dr. Ko and his team have provided us with top-notch dental service and would highly recommend them to our family and friends.
More
Support staff is exceptional and friendly. The doctor was thorough in his exam. There were teeth he could have stated were problematic but after testing them, he declared that they were fine. He did diagnose one cavity and while he cautioned me that it might need a crown, he opted to do a filling first as a conservative approach. The process to put the filling in went well and he declared that there was no need for a crown - that indicated to me that he wasn't trying to come up with excuses to do more expensive work. He seemed knowledgeable, thorough, and professional. I was pleased with the service.
More
the best!
More
Dr. Ko and his staff are excellent! They are very attentive to your needs and explain things thoroughly. Dr. Ko's skills will assure you a positive and comfortable experience.

I had my regular dental cleaning done by Maria today.She performs her work in such calm, professional, caring, friendly way that my visit to her is not something that is to be tolerated for my own good but a relaxing, even a session that i actually enjoy.I am grateful to Dr. Ko, Maria, and Kathy for excellent dental care - my teeth were in embarrassingly poor shape due to years of negligence when I came to Dr. Ko. Today, I have all healthy teeth and take good care.
More
The staff really take the time to get to know you, and Maria is the best hygienist I have ever had!

As always had a very good teeth cleaning visit. Maria is the most meticulous hygenist I have ever met. Dr. Ko came in at the end to review the X-rays. He is very professional and caring.
More
Dr. Ko and all of the staff at this office are extremely kind, patient, and gentle people. The atmosphere in the office, front and back, is comfortable and welcoming. I tell all my friends that it is worth the drive from Newark/Fremont to Pleasanton. A huge thank you to everyone at Dr. Ko's office for my last visit. I was very nervous and was definitely put at ease.

Dr. Ko did a great job fitting my temporary bridge. This is my first time having a bridge and didn't know what to expect. Dr. Ko explained the procedures and offered nitrous oxide if needed. The procedure went well and almost painless. Prior to seeing Dr. Ko, I did not see a dentist for almost 20 years.
More
Dr. Ko and his assistant performed multiple procedures during my visit. The patient's comfort is their highest concern along with high quality work. The staff is friendly and efficient as well. I highly recommend Ko and his staff!
More
John Ko was incredibly patient, kind, and informative. My mom and I went in as new patients and felt at ease immediately. The entire staff that works there are very genuine and down to earth people who make you feel at home. Good location in Pleasanton too.

Maria almost makes me look forward to dental cleaning.
More
I have been going to Dr. Ko for many years now and in spite of the fact that I am not a happy camper when I walk into any dental office, he and his staff do a great job of making the experience as relaxing as possible. Dr. Ko and his staff are always kind, warm and very welcoming. Dr. Ko is understanding of the fact that most people would prefer being just about anywhere than a dentists office so he does everything possible to make the experience as positive as he is capable. My wife is far worse than I am about going to the dentist and I could not convince her to go but, after some tooth pain she made the call. My wife was pleasantly surprised and very happy with the demeanor and service she received. If you are looking for a dentist that thinks of the client first, look no further than Dr. Ko.
More
Cleaning & X-rays went well, but I was disappointed that Dr.Ko was not available to examine a damaged tooth.
More
Great as usual
More
As always, Maria was very gentle cleaning my teeth. She and Dr. Ko always go out of their way to answer questions and provide reassurance.
More
Professional, courteous, and accommodating office! Though going to the dentist is probably not at the top of most people's "To Do" list (unless you are married to one), I can sincerely say that Dr. Ko and his staff do a fantastic job!! The overall office environment, modern equipment (massage chairs), and personnel demeanor actually make going to the dentist a positive experience!
More
The visit was very good.

Dr Ko and his staff are all very pleasant, thorough, explain diagnoses and potential problems, and are very willing to work with you.

A very friendly and professional staff. I've been coming to Dr. Ko for a couple of decades since he took over the practice of the former dentist in this location. Dr. Ko is awesome along with his staff!
More
Had two great experiences with Dr. Ko. The first was a regular checkup and cleaning which was so gentle I actually fell asleep during the cleaning! His staff was very courteous, friendly, and clearly very skilled. The second experience was during a procedure where Dr. Ko replaced two old fillings. The numbing shots were very gentle, Dr. Ko is completely calm and at ease, and the procedures went so smoothly I actually dozed off during parts of it! This is by far my best experience with a dentist so far, I'm very happy I found them and will be a long term customer for sure.
More
This is the best dentist I've ever been to! Dr. Ko and all his staff are supportive and helpful in every way possible. Their compassion and care goes above and beyond. I have been going to dr. Ko for almost ten years and have always been 100% happy with my care. It's all in the details and they cover them all. Great practice!

Dr. Ko is brilliant! I never thought I would look forward to going to a dentist, but that all changed when I first met Dr. Ko about 20 years ago. He is highly trained and an exemplary dentist. Furthermore, he is highly professional, friendly and genuinely concerned about one's concerns..I have maintained a healthy smile for many years, thanks to Doctor Ko and his very special assistant, Maria, who has cleaned my teeth for as long as I can recall.I recently had Doctor Ko do porcelain veneers on my front teeth, and couldn't be happier! Everyone remarks about how beautiful my teeth are! I love Dr. Ko and his dental family that includes Maria, Kathy, his lab lady and his receptionist Darlene. Doctor Ko is fortunate to have these wonderful, friendly ladies working with him! It's a real pleasure to trust in Doctor Ko!

It is a happy office and they go out of there way to make your visit a great experience. Dr Ko is so gentle and explains as he goes, making your visit a very positive experience. I must also say I had one filling done and Dr. Ko is an artist ,the nicest filling I have had done. .
More
I Wish I had gone here 30 yrs ago. Dr. Ko's clinic is next door to our family doctor. Our dentist, who we saw for more than 30 years, retired and we had to find a new dentist. After an appointment with our doctor, I decided to walk into Dr. Ko's office, and I'm glad I did. It was a very welcome feeling as soon as i entered the door. Ester introduced me to the staff and Dr. Ko. On my first appointment, Dr. Ko laid out my dental game plan after Kathy took a full mouth x-ray, and provided me with a very thorough explanation of what my procedure will entail. Afterwards, Maria, the dental hygienist, cleaned my teeth so well that I felt I shouldn't eat for days because I didn't want food particles between my clean teeth (just kidding!). Two weeks later Dr. Ko did my first procedure, i.e., a crown, which went very well and I am extremely satisfied with the result.
More
Came in for a cleaning m, stayed for the filling restoration.Last-minute opening and two old fillings were restored painlessly in an hour.Plus we caught up on the upcoming hockey season and our kids.I have recommended Dr Ko and they were very happy.
More
Always amazing care! Came in to cement on a crown and ended up getting a small cavity filled the same day! The entire staff is amazing!!
More
Maria always does a thorough job and is excellent! Thank you!
More
Excellent as always
More
Another great experience with Dr Ko.  I have had several crowns with previous dentists and this one was by far the best.  Really quick and though.  Everything feels so well and no pain during or after.    Dr Ko and his staff really set you at ease and are so professional. Once agin no up selling.   I never look forward to going to the dentist but I don't think I'll ever have anxiety over getting work done here.
More
Great as always! Kind considerate and thorough staff.
More
From Esther to Shelly and Dr Ko and Dr Gloria (all the people whom I actually met and assisted me) very professional but really showed they care about a patient.

Maria was awesome! She was very thorough with my teeth and gentle.

Dr Ko was very professional and explained every aspect of the visit in clear language, making sure I understood. He was respectful of the fact that I did not have dental coverage and was paying out of pocket. He offered suggestions and treatment plans without being demeaning. I will return.

My experiences at Dr. Ko's office have always been positive. He's very gentle and always makes sure I'm "doing OK" when I'm in that chair. :-) His staff is extremely friendly yet very professional. I was referred to Dr. Ko from a friend of mine a couple years ago and I would definitely refer him to any of my friends.

Dr. Ko is brilliant! I never thought I would look forward to going to a dentist, but that all changed when I first met Dr. Ko about 20 years ago. He is highly trained and an exemplary dentist. Furthermore, he is highly professional, friendly and genuinely concerned about one's concerns.. I have maintained a healthy smile for many years, thanks to Doctor Ko and his very special assistant, Maria, who has cleaned my teeth for as long as I can recall. I recently had Doctor Ko do porcelain veneers on my front teeth, and couldn't be happier! Everyone remarks about how beautiful my teeth are! I love Dr. Ko and his dental family that includes Maria, Kathy, his lab lady and his receptionist Darlene. Doctor Ko is fortunate to have these wonderful, friendly ladies working with him! It's a real pleasure to trust in Doctor Ko!

Thanks Dr.Ko for your great work, patience and always being on time!
More
This has been my family Dentist for the last 10 years!  I can't say enough about this group of professionals from the front desk - Darlene, our Hygienist -Maria and of course Dr. Ko...Wonderful group that makes you feel at home, the care that they provide with my children, myself and husband and more importantly their experience and customer service!  I have moved to Brentwood and have not found a local dental office yet and still drive to Pleasanton.   I have tried a dental office and won't mention name.  They obviously didn't make an impression... I may have to continue to commute until I find that right place.  For now, Dr. Ko and his staff has been amazing, and so far irreplaceable.   Highly recommend if you are near this location.
More
Great experience, as always!
More
I could not have a better dentist and support staff than I have at Dr. Ko's
More
Very happy with my cleaning.
More
Absolutely the Best!!!
More
Dr Ko is always great! He is friendly, takes a personal interest in you as person as well as a patient. As most, I am not someone that looks forward to a visit to the dentist, but if I must then it is Dr Ko that I want to have the appointment with. I live in Walnut Creek but he is worth the drive to Pleasanton to have him taking care of my teeth. Another good job Doc, thanks! Curtis

I love, love, love this dentist and his fabulous staff!  The front office (Darlene) is such a sweetheart and is so accommodating in making appointments. The Dental Hygienist (Maria) is great!  My teeth always feel as good as new after cleanings.  The Dental Assistant (I forget her name...sorry) is a true gem too !  And I can't say enough about Dr. Ko....he is phenomenal!  He knows his stuff and is great at listening and explaining possible treatment options.  Since my husband and I began going to Dr. Ko a few years back, several of our family members have started going to Dr. Ko and even the pickiest relatives are completely satisfied!  BTW, the same staff has been with him as long I've been seeing Dr. Ko, which says a lot about their friendly office environment .

Excellent, as always!

Maria was very kind and careful when she cleaned my teeth. At 51, I am starting to have exposed roots which are quite sensitive. So she applied some kind of Floride coating and topical anesthetic that really helped. My teeth felt clean and for the first time my gums actually didn't hurt. My last appointment was with Dr. Ko for a filling replacement. He was also very kind and careful. The procedure was painless and pretty quick. These people make a great team!

A '5+Stars' is given to Dr. Ko - and his impressive staff!  His position is, 'not just as an exceptional dentist' but with a heart for his patients.  In times past, i've always experienced unnecessary pain with other previous dental visits.  As a result, i've ignored having my teeth upgraded for many years - but then was forced into a position to have a more presentable appearance.  During my visit, no discomfort was experienced.  After mentioning that more 'booster injections' were required in order to eliminate the pain, Dr. Ko resolved the issue.  No pain with the injections, & no pain during the procedure.  I am looking forward to future visits.  After a recent exam with another dentist & then comparing other quotes, his prices are very reasonable.  I very rarely leave comments (quite obvious here on yelp  - but had to in this case).   Highly recommended!
