Ryan is a artist in dentistry my temporary crown looks good as it is . Jena his assistant is remarkably as good. I would recommend this dentist to friends and family

Quick and easy to get an appointment. Took very good care of me. Thanks

I would definitely recommend this dentist to all my family end friends. The personal is so nice en they do a very good job 👍👍👍i am so happy 😊😊to went there.

I had a wonderful cleaning yesterday. Staff are always polite and welcoming. My hygienist was a joy; she was very professional providing education and thorough while gentle in her technique. Highly recommend Miller and Simarro Dental Care.

Everyone was a joy. From scheduling(Taj) to the actual appt. Dr Ryan, the assistants, hygienist, were all so nice. Thank you all for a pleasant visit.

I am very disappointed with this dentist I had 2 crowns done and the dentist does not do the actual fitting and placement of the crowns everything is done by his personal that is why I am having pain when I eat. I never been to a dentist that does not take care if his patients and doesnt supervise his employees work. I went back 3 times so he can file the crowns to see if they will work but I still get pain when I eat on top of that last time that I went to see him to correct his bad work he charge my insurance now if I want to get a second opinion from another dentist I have to pay out of my own pocket.

Miller & Simarro Dental office is the best dental office and I highly recommended there practice. Going to the dentist has always been very scary it had prevented me over the years to go to the dentist. Since I found Miller & Simarro I get my teeth clean on time and feel very comfortable when I am in there office. They take there time to explain each step, check with you to make sure your ok during any procedure and go above and beyond to make you feel at ease.

They do a really good job, they are definitely in it for the the good service they provide. They pay attention to detail and make sure the job is correctly done!

Always outstanding and professional care at Miller/Simarro Dental.Truly top notch people all around.And now with the Covid issue, they are as truly prepared as is possible - well done!

Ive been going here for over 20 yrs. The staff know my name, i have never had a bad experience. The staff is amazing. Kuddos

Excellent care and thoroughly prepared for current conditions for all procedures. Felt very comfortable and confident regarding the professional responsibility towards staff and patients. Thank you very much for helping me maintain my standard dental care during the ongoing COVID concerns...

Great staff, very friendly. Follows all safety aspects to ensure everyones safe. Highly recommend.

Great knowable and friendly place. Keep up the good work you all and stay safe!

The last time I had 2 hours of dental work done at a different office was a nightmare! This time Dr. Simmaro & his assistant were so good, made sure I took breaks to rest my mouth, and made my temp caps perfect! And I’m a little nervous when it comes to shots in my mouth! I barely felt it! Thanks! ...💋 y*

Took my 5 year old for his first dental appointment ever (yes I know I’m late to the game). The hygienist was excellent with him- explaining everything every step of the way and was very kind. The dentist (Nathan) is great with kids and made my son feel very comfortable. Had a great first experience and will be taking the whole family there!

Been bringing family here for a few years after looking for a good dentist. Great work and front office and everyone easy to talk to. Aside from all needed work had a good whitening experience with their bleaching

Everybody at this dental office is welcoming and friendly. I actually walk into my dental office without feeling nervous. They take great care of my teeth. Dr. Simarro takes his time, he is gentle with the work he does. The dental hygienists take into consideration temperature and tooth sensitivities. I have recommended this office to many family members and friends

Excellent as always. They go out of their way to keep you comfortable. And believe me when I say that I am probably the most nervous patient. Every time they go out of their way to keep me comfortable. Excellent work as well. Had veneers last year and I always get compliments. Excellent start , excellent staff and excellent work!

I highly recommend Miller and Simarro...I have been a patient for decades.

The office staff was one of a kind. The Dental hygenest was very nice, and kept me informed every step of the way. Showed me my X-rays,explained in great detail what was going on.Dr. Nathan Simarro was very cool. He never once tried to push anything on me, he was thorough and what a great sense of humor, and the way to explain it I guess was a very casual attitude.The equipment they use is the best you can get in the industry, and my cleaning, X-rays and exam were all pain free.Dont hesitate, these guys are the tops in there field.

Absolutely the most friendly staff. We are new patients and they treated us like family. My husband is ill and they did everything to make him comfortable. He was worried they could not help him. He was so happy when we left the office. He commented to me on the way to the car, “I really like this place. Those people are great!” We go back in a month and I have no doubts about their professionalism matching the initial tone in the office. This is our new dental team! Highly recommended. *_*

Very Nice Staff, Felt very safe relaxed almost...id give a 5 but just feel a little Pressure to get certain things done to my teeth.... i understand concern ,just will get stuff done within a few months when i can... And Ill have Healthier Teeth then ill work on Whitening thank you guys so much!

The entire staff is always friendly, prompt, and professional. Ive been going to them for about 3/4 years now and have never had a negative experience. Highly recommend!

Dr Simarro and his team are AWESOME! They really listen to your concerns and questions and are patient and take the time to explain and answer all questions. They are very friendly and they always make sure you are comfortable! They are my lifetime dentist, I will definitely recommend them to all my friends and family 😊Lisa Lang

The staff are all very friendly. The assistant who cleans my teeth is very thorough yet gentle. She does a great job. The Dr. is very personable and he appears to be a smart, trustworthy person. I always feel like he is giving me an honest evaluation and not just trying to get money like some other dentists.

Ive been seeing Mark Miller DDS since I moved to Antioch in 1997 the overall quality and experience has been just priceless.. Mark Couldnt have picked a better associate Ryan Simarro DMD to share in and pass on the knowledge and quality of his great practice to his patients.. Its hard to find a good honest professional thats not all about the Mighty Dollar. Leaving the office this morning as walking out with one of his other patients and oh my gosh hes just so grateful he said hes never walked out of a place feeling more positive about the care he just recieved and the assistance to financially complete the work thats needs to be done..Thanks Mark Miller and your great Staff.

I absolutely love this laid back,yet professionally run dental office. The staff are always happy,no stress. Lovely decor.Latest technology in the dentistry.Very patient with booking future appointments,even if its an entire family:)My family and I have lived in Antioch for over 20 years. We use to drive to Concord for our dental care. But I am actually happy for this change:) Not a fan of the dental thing..But we all know if we have to go... this is the place to get it donein a relaxed.. serene place:)Thanks team!Deona Roberson

Who likes the dentist? I waited years and years to go and Im so glad I did they make you feel so comfortable like family. I highly recommend Miller & Simarro Dental Care. Such a clean & comfortable environment. The staff is amazing and they all make such a great team!

I have always been able to count on Dr. Miller and his staff to give me the best treatment around. Everyone on the Staff is the most polite courteous people you can find. I truly believe that they care about your well being and health.

These dentists are the best I have ever been to. This is a very high tech. office. Wonderful staff that is always professional and prompt. I have had a lot of dental work and had some good and bad dentists in the past 50 years. These 3 are the best!

Loved my first appointment! Great office, beautiful with relaxing music. Everything was very clean. Did all my paperwork via computer so it was quick and readable. Dentist was wonderful, excellent bedside manner. Xrays digital, so fast and easy. Staff explained every procedure and cost, clearly and in writing, with each procedure and what the insurance paid and what I would have to pay very clear. I am dentist phobic and I felt very reassured. I don;t know about pricing since I havent been to the dentist in so long but I will say even without insurance, my root canal will be about $300 less than I paid 4 years ago. I will follow up with another review if the quality doesnt stay this high.

Best dental experience Ive ever had. The office is clean and uses high end technology. The office staff is very friendly and show great customer service! Would recommend to anyone!

I was very pleased with the care I received today. Maggie was very professional & my teeth feel wonderful. The staff was welcoming & friendly. I didnt want to change dentists but glad I found you. K

While the quality of the work that the doctors do is adequate, the problem is how they take care of their patients after some painful procedures. No follow up calls to check on their patients well being after they leave. No post procedure pain medication after they do painful procedures on you.They say - just take tylenol or motrin. good luck. see you again. Inhumane post operative care - other dentists Ive asked even said find another dentist. High prices, zero after care pain management, not everyone is a drug seeker. Pull teeth, treat the patient, dont leave them hurting. Found another dentist - Glad we did. Patients beware!

I just had the best experience ever. Jennifer is the best Hygenist! My teeth are singing they are so clean.My previous visits were with Dr. Simarro for a crown. Pain free and he saved me from getting a root canal. Bravo!

Most people hate going to the dentist, but I can honestly say that I always have a great experience here! The staff and doctors really know what they are doing and I feel like the equipment they use is modern and up to date. I hate getting injections and Mark knows how to do it without any discomfort at all. Everyone is always super friendly and I look forward to my six month check ups :)

My experience at Miller & Simmaro dental care is always a pleasant visit. Never have had any bad experiences since being a patient since 2004. They take care of you like your one of them own. This dental care is highly recommended! Sue is the best and is always helpful along with the rest of the staff

Ive been going to Dr.Miller ever since I was around 5 or 6 and am now 20. Theyve always been very nice and really look out for the health of your teeth. I love that they put your best interest first. If youre looking for a dental office to call home this is the place!

Miller and Simarro Dental Care has been great! They are always professional, caring and take pride in offering stellar customer service. I would recommend this dentistry for both adult and childrens dental needs.

The dental hygienist that did my cleaning would explain what she was doing and explained my X-rays to me. And I was able to get my cavity fillings done right after they found out I needed fillings. Everyone is very friendly!

They are always friendly and courteous. Nathan walked me through everything he was doing. The day after he called to see how I was doing. He also told me not to hesitate to call him or the office if I had any questions or concerns!

Great care and friendly staff! My hygienist, Mary, always has the best conversation and makes sure Im completely informed with my oral health. Recommending this office to all of my friends and family.

It took me over 3 years to find a dentist I felt confident in and could trust. Dr. Ryan Simarro is wonderful! I had 3 crowns done by Ryan and his staff. Everyone is friendly, kind and professional.

I have recently become a new patient and am so happy I was referred here! First of all the front staff is extremely welcoming and friendly! The dental assistant and dentist walk you through everything step by step which eased all of my anxiety. Highly recommended!!!

Awesome, friendly and helpful staff. Never had a bad experience and have had all three dentist work on me. Comfortable furniture and great view. Would recommend to my friends and family.

My visit with Dr. Simarro went very smoothly. The office and staff are very professional and very helpful. I was very relaxed and had no problems with the crown prep. Looking forward to my next visit to finish up!

Dr Miller and Dr Simarro have a great attitude, provide excellent dental care. Their office is very clean and their staff provide great customer service as well. I drive a long distance to their office but I know I could trust them with all my dental care needs.

This is my first time going to Miller and Simmaros Dentistry, And I have nothing but praises to say about this place. The staff is so courteous and nice, they made me feel welcome for my first time and the dentist in over 15 years. I deathly recommend them, that it doesn’t help but I also got good news I have no cavities. Will be back soon

Great place to get you teeth checked and cleaned!Dr. Nathan & Jen were great and very thorough. I would definitely recommend them for any dental needs.

They were very accommodating I was given an after work appointment. Dr. Simarro was gentle with the instruments and the drill. I hate the sound of that annoying drill but I was able to relax while listening to music through my earbuds. Dr. Simarro worked at a consistent pace he didnt rush even though it was late evening. The staff is always polite, patient and they take time to explain procedures so that you are comfortable with your treatment. I love how this office is up to date with the newest equipment and lastest trends in dentistry. You can trust Dr. Simarro he is very knowledgeable and confident that you will be happy with his work. I love it here and I love my celebrity smile ! Thank you! 💕

Been coming to the office for years and and have referred many friends and family. From day one have always received professional, honest, affordable care. Never have I been kept waiting more than a few minutes. Also appreciate that they are up on the most current treatment. Ive had invisalign braces (cant say enough good things about that experience!) and whitening services. These are good, honest people performing exceptional care!

The team here is all around wonderful. Always polite, gentle with their tools and genuinely kind. They made me love going to the dentist again

I have been going to Dr Miller and Dr Simarros office for years and love it. The people are great and they do good work. I recently went in for a minor pricedure and I was a bit nervous but I had nothing to fear. The appointment went smooth and I was on my way in no time. I have already scheduled my next visit!

Top notch professionals!!! Keep up the good work. IF YOU ARE LOOKING FOR OUTSTANDING DENTISTS DO NOT HESITATE IN CONTACTING THEM!!! LOTS OF TLC AND THOUGHTFUL CARE!!!!

I came to Dr Miller about 20 years ago with many fears about having any dental work done. Not only did he calm my fears but I cant imagine seeing another dentist ever again. He has a superb bedside manner and friendly disposition. Also, he amazes me with his constant research of the latest in technology regarding his practice. Now he is our family dentist and we love the whole staff there!

SO GLAD I found them. My first time here was Feb 2016 because my tooth chipped. The 2nd appointment was supposed to be 2 weeks after I had seen Dr. Ryan but an emergency situation happened and had to cancel that same day that I was supposed to come in that early morning. The office ladies were not mean at all like some other places Ive been when trying to cancel or reschedule my appointment. They were all so welcoming and made me feel at ease with everything. They even watched my baby girl while I had my teeth taken care of today. ALL such wonderful people and so SWEET all around. I will be a patient for life :)

Well I have to say A very good experience, under the emergency scheduling. The staff was great and (Taj) was so accommodating. Dr. Nate S.was so professional. He explained everything before and after the procedure to the fullest.

Had a wonderful experience here! Everyone was super friendly and efficient. Would definitely recommend this office!

The staff is always friendly when they greet you. My appointments are on time, I never have to wait in the waiting room nor once I am taken back. Everything is explained clearly so i know what to expect. The office is clean and pleasantly decorated. I have been a patient at this office for almost two decades, obviously I am quite happy with Drs. Miller and both Simarros.

I would definitely recommend these dentists and their staff. My husband and I have been coming here for over ten years. They are wonderful!!!

Friendly & helpful staff work hard to make your appointment times work with your schedule. Explain their observations clearly and honestly.

Always a good experience. No waiting, got right in - even for last appointment of the day. Staff is always pleasant. I would recommend Dr. Millers group to anyone looking for a great dental practice.

I have been a patient here for years. The staff is always very friendly and make you feel very comfortable. I highly recommend Dr. Miller and Dr. Simarro for any dental needs.

Couldn’t asked for more. You guys are the best and very friendly. Extremely recommend this place to anyone who is in pain like myself.

I recently had a few visits with Dr Simarro and his team for cavity work. Everything went great, my cavities are filled and I loved the energy from him and his team. There was literally no wait time on both my visits and I cant wait to come back for cleaning!

I have such a fear of the dentist! When I first began my visit with Dr. Miller over 10 years ago, he listened to my concerns and heard my past pain. He has always remembered our first meeting and his dental care has been supreme. I wouldnt go to another dentist if you paid me! The office staff - Sue & Taj are very personable and they make accommodations to fit me in on my inflexible schedule!Thank you Dr. Miller and staff! Every visit gets better and better...Thanks Jen! I would highly recommend this dentist!

Friendly and professional staff. I am a nervous person at the dentist and they always put me at ease. They work quickly and are very gentle.

I have been a patient at Miller & Simarro for over 15 years. The are is excellent! Staff is courteous, professional and the Dr.s Mark, Ryan and Nathan are tremendous.

Love this place! Staff is always friendly and welcoming. Wouldnt trust anyone else with my pearly whites! 👍🏻

The best, most gentle dentist Ive ever had. Ryan Simarro is an artist. He and his team gave me my smile back.

Very happy with the service here. All 4 in my family needed work done as we had waited way too long to find a new dentist. The entire staff has been professional and friendly. Would highly recommend them.

Going to Mark Miller for 37 years... Best Dentist Hands Down! The staff, Mark, Ryan, and Nate are always a pleasure. Highly recommend!

As soon as i stepped in the office i was greeted with a good morning and a smiling face. That was a relief, because i know im not a huge fan of the dentist. Staff is super friendly and easy going. I think im excited to go to the dentist now.

The office has a warm and friendly appeal They always greet me with smiles and ask how I am doing. I cant wait to get my teeth cleaned!!

The staff is very friendly and professional. They get you in at your appointment time, theres no waiting around the lobby wasting your time. The service is quick and efficient with minimal transition times between x-rays, to cleaning, to polishing, to exam...Boom your done and on about your business!!! Thats why I keep going back!!!

Hands down, this is the BEST dental office around! Everyone is so friendly, welcoming, and professional. Dr. Miller & Dr. Simarro and their staff go above and beyond for their patients. I would never go anywhere else.

Always on time, Always friendly...I never had to wait more than 3 minutes before getting into the chair.

Dr. Miller and all his staff are warm, welcoming and professional. I am a long time patient, over 20 years, and would recommend them to anyone.Debbie Valladao

They offer great professional care in a friendly atmosphere and show genuine concern for their clients wellbeing. Highly satisfied!

The entire staff is friendly. They always have the latest technology. If you are someone who is nervous about the dentist then you wont be disappointed coming hear.

I love this office !!! They provide an amazing personal feeling of family but with exception level of professionalism which they carried through out the entire process from making appointments, to getting teeth clean and to even more evasive dental work. This office cares about their patients.

Been with them for years! Highly recommend. Very nice, thorough and professional. Never have to wait!

Staff is friendly, professional and very helpful with all my questions and concerns. I am very happy with the results and would highly recommend Dr Simaro to my friends and family.

Always a great experience. Its all about the great people that run that business. Thanks!!

My experience was absolutely great and wonderful. I love your services and staff I would recommend to anyone.

Great dentist with excellent customer service. They have a very knowledge staff and are very accommodating!

Simply put... The best! Professional, informative and most of all, painless.

Office is always clean and the staff is friendly and they take great care of you. First rate and top notch!!

Today was my first day at this dentist. My experience was great! My hygienist Mary was super friendly and very attentive. She also gave me plenty of breaks which is needed with my TMJD. Dr. Simarro will be my new permanent dentist.

Love my dental team up here on the hill best view as well!! Best dentist in the Bay Area. If you want cosmetic dentistry this is the place to come.!!!

Excellent experience, friendly staff; Ryan was an excellent dentist, friendly and professional! I would definitely recommend this Dentistry to all my family and friends !!!

Good service quick called back for emergencies,but while we are at waiting room one of the dentist was screaming at staff because they were talking. it just didnt look professional should have been done in private.

I had a a previous bad experience at a dentist while getting a root canal it was the worst pain ever! Besides my tooth hurting that doctor hurt me even more. I googled and yelp for another doctor where I can go to where I can no longer be afraid and scared while eating dental work. I found this office and the moment I stepped in I was in dental heaven. The staff was absolutely awesome and the doctor was amazing. We did a consult and he broke down what needed to be done explaining every single thing to me. Im thankful for finding them and now Im ready to get work done, Ill make sure to leave another comment after said and done.

Everyone is always friendly. The dental assistants ask questions and are gentle with cleaning.

Have been coming here for 16 years, professional,with cutting edge technology, teeth are well taken care of. Great group of people.

Great dental service. All 3 of my kids ages 10-17 have had good experiences and really like the staff a lot.

Dr. Miller goes out of his way to make you comfortable and make the experience pain free. He is the best!

Excellent staff. Efficient, professional operation. Stress at a minimum. Highly recommend Dr. Miller and his office.
