EXCELLENT Based on 338 reviews Posted on Karen GrosecloseTrustindex verifies that the original source of the review is Google. You are in good hands with Dr Horiyat and her team!Posted on James KenneyTrustindex verifies that the original source of the review is Google. I had to have a lot done, they took good care of me.Posted on Elise MarvinTrustindex verifies that the original source of the review is Google. Aria dental is everything I want in a practice. Extremely knowledgeable about holistic health care in general but specifically with the mouth and teeth. They have all the latest technology and they are just really human. They care, they explain things thoroughly and they’re easy. They do not nickel and dime you and because I was at another holistic dental practice initially… I promise that’s a thing you want to avoid. At Aria they are kind, and take the time to educate and are reasonably priced considering the amazing cutting edge holistic dental care you receive. They are a five star practice for sure!!!Posted on Stella RoseTrustindex verifies that the original source of the review is Google. I absolutely loved my visit here. I usually get severe anxiety going to the dentist and I felt so comfortable here. everybody was so kind and so knowledgeable. Big thank you to Steve and Shima for making the first appointment process so easy. this will be my regular dentist from this point onPosted on Lisa MylesTrustindex verifies that the original source of the review is Google. I travel quite a distance to come to this office and it's worth EVERY mile. My dental hygienist, Jonathan,(hope I spelled it right, lol), is a pro at what he does. I honestly feel so relaxed in his chair that I tend to drift off to sleep. Everyone there is so welcoming, respectful, and professional. It makes what use to be a stressful necessity for me, so much more relaxing. I can't recommend it enough. 😊 5/29/26 Just a follow-up to my previous post. I sincerely CAN NOT rave enough about this dental office as a whole. From the genuinely warm, friendly greeting that you get from Steven and Shima at the front desk, to comfortable and relaxed feeling that I personally got from Anna and Radian during my cleaning and follow-up procedure. Which I'm sure reflects the rest of the staff as well. Not to mention the glue that holds it all together, Dr. Maryam Horiyat. When I tell you this woman knows her craft.......she KNOWS HER CRAFT. She was patient and attentive to my needs when it came to my initial discomfort that made the procedure to correct a filling which was done at a different dental office, an extremely pleasant process. So much so that I almost drifted off to sleep. No exaggeration. From the state of the art equipment and execution, to the stellar professionalism, I absolutely understand why Aria Dental has clientele/patients that come from all over California and other states as well. Thank you again. 💜🫂💜☺️Posted on patricia hallTrustindex verifies that the original source of the review is Google. Exceptional in every way. From the moment you walk into the office, you are treated with kindness, respect, and professionalism. The entire team goes above and beyond to make patients feel comfortable and cared for. The dentist is highly knowledgeable, gentle, and meticulous. I have never experienced such a combination of expertise and compassion in a dental office. The quality of care is truly outstanding. If you are looking for a dental practice that genuinely cares about its patients and provides top-level care, this is the place to go.Posted on Cassie CashTrustindex verifies that the original source of the review is Google. Dr Horiyat is the only dentist I trust with my teeth. I found her in 2024 after a botched tooth extraction and she was truly the only one who would help me. Her approach to dentistry is unlike anyone else! She is an amazing, talented dentist who truly cares and will listen. She won’t stop until she finds a solution for you. I’m grateful to have found her!Posted on Keri SukutTrustindex verifies that the original source of the review is Google. Love this dentist. Staff is great and organized. Everyone is super friendly and they go above and beyond. I have had nothing but a positive experience.Posted on Sara M Al AsadiTrustindex verifies that the original source of the review is Google. Unlike any dental experience. Highly qualified dentist and lovely staff.Posted on Adin RuddTrustindex verifies that the original source of the review is Google. Cleaning was gentle and easy.
