Our Patients Are Saying...
EXCELLENT Based on 322 reviews Posted on Kimberly ScottTrustindex verifies that the original source of the review is Google. I had the BEST CLEANING TODAY by dental hygienist Carolina Martinez!!! Love Dr. H and her office staff, their services are top notch. I’m a fan of the ozone and laser treatments I know they have helped resolve my dental issues and given me better gum health!! I appreciate the proactive holistic approach, it really makes a difference and worth the added expense.Posted on tina toufaniTrustindex verifies that the original source of the review is Google. Dr. Horiyat is truly one of the best; extremely knowledgeable, with a remarkable eye for detail. She earned her bachelor’s degree from UCLA and attended dental school at UCSF, which is clearly reflected in the precision and quality of her work. She takes the time to explain everything thoroughly and makes you feel completely comfortable and confident throughout the entire process. Her office is lively, spotless, and beautifully maintained, creating a refined yet welcoming environment. She is incredibly patient, attentive, and genuinely cares about her patients. I highly recommend her to anyone looking for exceptional dental care.Posted on Jennifer LawrenceTrustindex verifies that the original source of the review is Google. I thought the hygienist did a thorough job cleaning my teeth. She was enjoyable to interact with as well.Posted on JohnTrustindex verifies that the original source of the review is Google. March 12, 2026 This review; for my wife Joan; outlines her almost one year successful dental restoration; procedures; treatment; project at Aria Dental. The brilliant work was performed by Dr Maryam Horiyat, DDS and her dental staff. I wish to additionally thank the office staff for their concern, friendliness and helpfulness. If you peruse my initial review for my wife’s mouth; it was a functional and aesthetic mess. A traumatic accident years before to her mouth and an attempt to fix issues over several decades by less than competent dentist and oral surgeons had left her with a smile she was less than thrilled with and a mouth full of teeth that did not chew well. Dr Horiyat presented a dental plan to resolve all my previously mentioned issues and successfully set out to both restore my mouth with advanced dental restoration techniques and at the same create a wonderful feminine smile for my wife Joan. Amongst the work performed beautifully was repairing a cracked tooth; replaced 5 crowns; and replaced/fitted a new porcelain bridge. The work was performed to the highest dental standards without pain. My wife can chew food; her smile is pretty; the teeth color is attractive and all the dental work feels good. The metallic mouth taste is gone; dental headaches are gone and my smile is back. Thank you Dr Horiyat. — I first saw Dr. Maryam Horiyat 5-20-2025 for my extraction, bridge and or implant consultation plan. The doctor is highly professional; current in best dental practice’s and very carrying and respectful. My new dental goal is to correct the expensive work another dental team/office did and failed at resulting in a bacterial root canal infection; a 24/7 metallic mouth taste; dry mouth; loss of sleep; headaches; an inflamed lower implant plus an ill fitting upper full bridge with a poor bite. I left our consultation with the belief that Dr. Horiyat and her team are the right people to remedy my dental issues successfully.Posted on Laleh YasamifarTrustindex verifies that the original source of the review is Google. We are so grateful to have found this practice. The entire team is incredibly kind, gentle, and patient with children, which makes such a difference for families. The biodynamic and natural approach to dentistry was very important to us, and it’s clear that they truly care about the whole child, not just their teeth. My kids feel comfortable and supported every time we visit. It’s rare to find a dental office that treats families with such warmth and genuine care. We feel very lucky to be patients here.Posted on Debra TippinTrustindex verifies that the original source of the review is Google. Kind attention to my needs and what I wanted … very professional with all up to date equipment… I recommend them HighlyPosted on Lachelle NassieTrustindex verifies that the original source of the review is Google. Dr. Horiyat and her team and truly amazing! Treating our entire family (adults to kids), they continue to provide knowledge into true ROOT CAUSES! Dr Horiyat has personally come alongside our 9 year old and instead of jumping straight to an expander, she did a sleep study discovering our oldest has sleep apnea and went over the steps to heal this; which is what we all want- true healing. As a holistic dentistry, it's not a turn and burn office (and for those unsure - it's a different approach then a typical cleaning so understand the environment in which you seek service at). For insurance, yes, you pay upfront however they are immensely helpful in sending in all the documentation to our insurance on our behalf unlike many other holistic offices I've personally experienced. For us, Aria Dental has been a long sought after answered prayer and we not only are blessed by them, but sincerely recommend.Posted on Jeanine Starkey FisherTrustindex verifies that the original source of the review is Google. The whole team at Aria Dental are totally accommodating and very kind. I had to reschedule an appointment. Steve is incredibly efficient and wonderful to work with. I needed to bring in my kids during the rescheduled appointment, all the staff were so patient, engaging, and interactive with the kids. They even gave them balloons and goodies during the appointment. I am new to Aria dental and this area, they have made this such a delightful experience. I am looking forward to their care and healing hands.
