They’re the very best! Every time I get any kind of treatment from Oak Tree Dental, I leave feeling so well cared for and extremely grateful. I’ve seen many other dentists in my life and not one compares to the level of expertise and ease that I’ve received from this place. I can’t recommend them enough!

I suffered a TBI with neurological Lyme disease for many years. I wasn’t able to withstand getting fillings. Lyme disease is very destructive to enamel and collagen so my teeth were quite the state. My nervous system and my brain were also still healing. I saw one technically excellent dentist in Occidental, who was emotionally unable to cope with my situation. His lack of empathy and hostility and dismissiveness… I don’t think I can express the impact when you’ve already been through so much. I was shocked, horrified, and I also knew I was right next to needing a root canal and this dentist dismissed me like I was an annoyance. And thank God he did. Because he was a terrible soul. And then I met Dr. Grados at Oak Tree dental. He was so kind, he was so present and calm. He listened and watched me, where he didn’t understand, he was keen to learn and fascinated. He enjoyed his work. He was diligent and happy, even as we found a way to manage my symptomology with his goals for my healing. He is excellent in every way and you can tell from the kindness and the sweetness in the whole office that they are proud to work there, and that he has chosen each one as a reflection of what he values. If you’re out there and you’re dealing with a neurological issue, a devastating illness, or you have chronic pain no one else can see…This is the dentist to go work with. And his staff included

I always have a great experience when I am here. The staff is amazing. Dr Gratis is very thorough and explains it all to you as he does the work. He has a calming presence which relaxes me. I have high anxiety going to any dentist. Here I am able to handle it better. Highly recommend Oak Tree Dental

I have been going to the same dentist office for 56 years and he retired. I had great referrals from a friend for Dr.Grados.and his staff. So hard going to someone new but they did everything to make me comfortable. All very nice and explained everything. Also Dr. Grados took his time with me and never seemed to be in a hurry. Would recommend him and his friendly office highly. Had a lengthy procedure today and Dr. Grados did a wonderful job. He is so kind.Today I went for two crowns. Dr. Grados makes them there . No temporary’s, no coming back for permanents. Amazing and meticulous. Had my teeth cleaned by Connie. She is so lovely and kind.

Good experience. I don't like going to the dentist but the staff and the Dr are good at making me feel relaxed. I was taken on time. I was having my teeth cleaned. The higentist was very kind and always remembers me. She makes me feel relaxed. Before I knew it my teeth were clean.

I can highly recommend Dr Grados at OakTree Dental in Sebastopol California. His hygienist is gentle and friendly and the rest of the staff are very professional and friendly. Dr Grados does a great job, which makes it a lot easier to want to go to the dentist!

I had my new patient exam with Dr. Navarrete and Andrea today, and they were a great team! Oak Tree Dental was referred to me by some friends of mine who go there. The Doctor answered all of my questions I had about my treatment; they were very clear about the timeline and what to expect, which made the whole process so much easier for me. Thank you to Dr. Navarrete and his team for being so friendly and knowledgeable. I appreciate the time they took to make my visit so comfortable. Highly recommend! 🙂

I'm a pretty tough mama EXCEPT when it comes to the dentist (ok and ticks too but who's not afraid of those!) I embarrassingly went wayyyyy too long without dental care out of fear. Rather getting cavities than go back.I was referred to Oaktree for that very reason and can not be more grateful. They are so, so kind. Never making me feel bad having gone so long and very attentive to my fear. Communicating everything they are doing before they do it, checking in constantly, and taking breaks for deep breaths when needed. Oaktree's helping get my dental needs back on track while making me feel comfortable and confident about going back. Big nonjudgmental, kind, nurturing sweethearts.

Oak Tree Dental is awesome. Dr. Gratos and his whole team are great. They’re super friendly and professional. The office is nice and their operation is really organized. I’ve never waited for more than 5 minutes for an appointment. The care is great, they’re always very clear with their recommendations and are excellent about educating you on oral hygiene and treatment plans etc…highly recommend!

2021 - June I just moved here a few months before I contacted them, and was pleased that my call was returned. they told me of all the details which would be done. I also needed two crowns, etc. and the whole things was done the same day! I was surprised that they didn't send me home with two temp ones!everyone is nice and attentive.Update: I went again for cleaning and that was the best cleaning I have had for a long time.Update: 2024 This is an amazing and professional office. very caring, clean, straight, friendly, on time, and they use latest technology.

Dr. Grados and his staff are extremely competent, friendly and reassuring, the office is immaculate and appealing, the pricing is quite competitive (especially their discounted plan for people without dental insurance). Exams are thorough, in-house fabrication and fitting of dental crowns by Drs. Grados and Navarette have been impeccable.
