Our Patients Are Saying...
EXCELLENT Based on 304 reviews Adin Rudd2025-09-23Trustindex verifies that the original source of the review is Google. Cleaning was gentle and easy. The hygienist was kind and listened to my concerns, answered my questions and gave me good advise for my dental care. She was also very kind. Alyssa Lewis2025-09-10Trustindex verifies that the original source of the review is Google. I received the best dental care at Aria Dental. The team is professional and kind. Through her knowledge and holistic approach, Dr. Horiyat was able to find the root cause of my dental issues. She worked with my schedule, made sure everything was completed with care and attention to detail before I left for college. I highly recommend Aria Dental. D N2025-09-09Trustindex verifies that the original source of the review is Google. Wonderful, caring, professional dental practice which finally steers me in the right direction with my oral care. Staff have the utmost care for new and existing patients. A friend recommended me and I will be bringing my kids from here on in. Doctor Maryam Horiyat has her heart in the right place and I’m very grateful for that. Justin F2025-08-23Trustindex verifies that the original source of the review is Google. If you are seeking an alternative approach to dental care, then Aria Dental offers it. In fact, I believe they are the only one in the area that does. The support personnel are quite kind as well. All the procedures are quite pricey due to the way they position the services (and most insurance doesn't cover it). After experiencing Aria Dental for a couple of years, I can confidently say that they use the holistic approach purely as a marketing niche, which allows them to charge higher prices and to "stand out" in a rather crowded market. It is worth noting that the dentist does not perform a number of the procedures. For example, when my wife received an implant (a multistep process), they shipped in another doctor who was certified for the extraction, as well as the nurse anesthetist. Then, when the implant was placed, one of the assistants performed that process instead of Dr. Horiyat. That was surprising. The entire thing was essentially outsourced. As mentioned by some others, you'll get a feeling that they are in a hurry for their appointments. Perhaps overbooked, or to maximize revenue. Either way, you'll be ushered in and out so that they maintain their tight schedule. On a personal note, in 2023 I was told by another provider, SoCal Perio Implants, that I needed gum flap surgery. My wife was going to Aria Dental, so I figured I'd ask for a second opinion. Dr. Horiyat was adamant that gum flap surgery was not needed, and that I'd be fine with LANAP Laser Gum Therapy. I opted for the LANAP procedure, but it didn't work. My issue came back after two weeks. I went back to SoCal Perio Implants and saw Dr. Caplanis (a well known and respected Periodontist in California). Highly recommended by the way. I told him what I did, and he was annoyed with me, understandably. He said that he does LANAP procedures too, and if he thought it would have worked, then he would have recommended it (and that he would have actually preferred to do LANAP because it's an easier procedure for him, but for a similar payment... making it an easy payday, but he knew it wouldn't work). I laughed when he told me that. He's confident and direct, and it's warranted. Anyway, I did the gum flap procedure with him and all was resolved. Afterward, I was pretty upset at myself for wasting my money on the first procedure, but honestly, that one was on me. I should have trusted my gut and went with the expert. However, I was a little bit annoyed that my experience wasn't even acknowledged by Aria Dental. They had my money, so they were happy. So should you choose Aria Dental? If your priority is purely holistic dental care, and none of what I shared gives you pause, then maybe you'll be more inclined to overlook how things work there. Louis Alvarez2025-08-11Trustindex verifies that the original source of the review is Google. I recently had an exceptional experience at Aria Dental when I went for a cleaning and revision of my Invisalign trays. I was very impressed with the professionalism, knowledge and clinical expertise of all the staff and especially with Dr Horiyat. She is a true perfectionist and did a great job in repairing my bad bite with Invisalign. I highly recommend Aria Dental to anyone looking for state-of-the-art dental care. Marla Welsh2025-08-09Trustindex verifies that the original source of the review is Google. Excellent Doctor care with most caring staff ever!!! I’m so thankful to have the best care in dentistry!!! Naomi Machimura2025-08-09Trustindex verifies that the original source of the review is Google. Jon has been taking care of me in last few times and I am very happy they found him. In last few times, I had to ask him not to use the machine to clean because my teeth are very sensitive. Today he used the machine the first time with me, and I barely felt discomfort. I strongly hope they keep him for a long time. Serena Chang2025-08-08Trustindex verifies that the original source of the review is Google. Aria Dental is the best dental office we have ever been to. We were looking for a holistic dentist and this office is it. Dr. Maryam Horiyat is extremely knowledgeable and gentle with toddlers. Her entire staff is very kind and competent - especially her front office Shima and Steve. I would recommend this practice without reservations. Carmen Garcia2025-08-06Trustindex verifies that the original source of the review is Google. Staff was very kind and professional especially Louis, my nurse and Dr Pham. They were very patient and answered all of my questions and concerns. I will definitely refer them to family and friends. Thank you all for a wonderful service !
