John W Sinclair, DDS

My first ever Unilocal review, just to say I had the best teeth cleaning ever today with Kathy at John Sinclair DDS, it could not have been better, my teeth feel so clean! She is so thorough and so nice, can’t wait to go back, and who can say that about the dentist!

Dr. Sinclair is an amazing, accommodating and virtually painless shot administering dentist. My family and I have been going to him for over 20yrs and he has been there for us during non office hours in various dental emergencies. I also enjoy the fun and upbeat staff. Kathy is excellent at making teeth cleaning go by smoothly and quickly. Nanette, the assistant, is funny as heck. Cindy, at the front desk, is great at keeping things going smoothly and making sure we remember our appointments. I would recommend this office to anyone

I’ve been going to Dr. Sinclair since is was 5. Dr. Sinclair went WAAAYYYYY out of his way to help me out. This past week I got a hold of Dr. Sinclairs office because of a terrible tooth pain I was having. This pain had been going on for months but it finally got to a point where I couldn’t stand it anymore. When Dr. Sinclair took a look at the X-​ray and at my tooth I had no doubt that he really knew exactly what he was doing. He gave me clear instructions on what needed to be done, adjusted an old filling and I was on my way. Highly recommend!

My husband and I have been patients of Dr. Sinclair’s for several years. He and his team are amazing and provide outstanding dental care. We have been going there for the last 5 + years and they have always been caring, friendly, and done an amazing job. If you haven’t been in a while and are looking to get back into a great routine, they will help you make it happen!
John Sinclair and the team rock!

I have been seeing Dr Sinclair and Kathy their Dental Hygienist for over 16 years. I started off as having extreme fear of dental offices. Both Dr Sinclair and his wonderful staff helped me along with numerous teeth cleanings, a few minor fillings and check ups throughout the years.
I now have no fear of dental work and would recommend this office to anyone who wants a professional and pleasant experience. My daughter is now a patient.
Thanks for reading!

I have been going to Dr. Sinclair for almost 7 years. I have had crowns, fillings and extractions done. Dr. Sinclair has a knack for thoroughness and precise procedures. He is genuinely concerned for the patient’s comfort. Every procedure that I have went through were definitely NECESSARY (needed) to keep my teeth healthy. To say that he and his staff do quality work is an understatement. All my dental work have remained to this day a testimony to their thorough, intricate work. As for billing and insurance issues, Dr. Sinclair’s assistant Cindy has always been helpful and willing to answer questions about payment. They will assist you in offering the most affordable options. I would not hesitate to recommend Dr. Sinclair to friends and colleagues.

Today, I had my first ever ‘root canal’ procedure. Not something most people look forward to, and yet I was pleasantly surprised. Dr. Sinclair and his staff were so caring, professional and technically expert that they actually made the experience fun. It didn’t hurt at all, and Dr. Sinclair answered all my questions very thoroughly. I’m a patient for life, and I will send all my friends and family to this amazing office!

RECOMMENDS UNNECESSARY PROCEDURES!
When I moved to Petaluma, I gave John Sinclair a try. He used some hokey apparatus hooked up to a small TV monitor to look into my mouth, after which he said I needed NINE FILLINGS — WITHOUT ANY X-​RAYS BEING DONE. I had never needed fillings before and had been getting regular check-​ups and cleanings my whole life, so I was both alarmed and skeptical.
I opted for a second opinion from another DDS in Petaluma and I am very glad I did. The other DDS dismissed John Sinclair’s recommendation as unnecessary!!!
I was a new mother at the time and terribly sleep deprived, so I didn’t have the energy to report John Sinclair to the BBB at the time.
Years later, I am still moved to write this negative review of John Sinclair. Now, I finally have done it. I hope it will save someone from having to have unnecessary dental work done.
I still haven’t needed one filling in the six years since I saw him!
