Dr Ash is simply the best. I have been going to Dr Ash since 2021, back when I was at Chapman University. My first visit was after I chipped my front tooth in an accident. I did a ton of research when this happened to me because I was not only in a ton of pain but was missing half of my entire front tooth, and Harmony Dentistry had by far the best reviews, so I decided to go with them and I am so glad I did. When I made the appointment that night of the chip in complete hysteria, he moved appointments around and opened up the practice at 8 am the next day so I could come in as soon as possible and not miss my important class finals. The day I went in, they placed temporaries on two teeth to fix my smile and make me feel more comfortable, and Dr Ash made sure everything looked perfect and that my permanent teeth were ordered and ready. That experience completely changed the way I view going to the dentist and doctor standards in general. Since then, I have continued seeing him not just for cosmetic work, but for cleanings, cavities, and anything else I have needed. I now live in LA and still make the drive from Beverly Hills to Mission Viejo about twice a year because I genuinely love this place, the people, and Dr Ash. The environment is amazing, and I have never felt more comfortable or trusted a doctor more. He truly is one of a kind. He always follows up after appointments to check in, which is rare. For example, today I went in to get a cavity fixed, they gave me my favorite complimentary microbial mouthwash that is normally pricey and great for your gums, and Dr Ash personally called me after the work day to see how I was doing. Not only that, I have texted Dr Ash many times on multiple occasions with questions and concerns off the clock, and he always responds promptly and is incredibly helpful. On top of that, they have incredible technology for super easy X rays and seamless retainer and Invisalign tray making, and everything is extremely efficient. The office itself is spotless, great layout and has beautiful natural light with great views. I could not recommend Dr Ash or Harmony Dentistry more. read more

I had gnarly anxiety around the dentist, and it prevented me from regular dentist visits. The folks at Harmony have totally turned that around for me, and now I look forward to my visits. They are personable, transparent, and explain everything clearly. I don't feel like I'm being talked at, or made to feel shameful about my teeth. They also gave me a best coarse of action to move forward and made everything feel much more manageable. I left the office with confidence! I don't care where I live in OC, I will make the drive every time. read more

All the staff and doctors are really friendly and catering to you and your specific needs. I felt so comfortable and knowledgeable about my dental procedure since they take the time to have a conversation with you and walk you through every step as they're doing it. No surprises and no anxiety! Shout out to Kathy who remembered my Netflix movie I was watching ready to go at the exact spot I left off from last time and I also got a hand paraffin wax treatment during the entire procedure with her that left my hands feeling soft and moisturized during this cold weather. I highly recommend this place. Is it weird that I love going to the dentist now? 10/10! read more

Dr Ash, Linda and Margo are the best! Been going here for years and I am not the best patient, but they always make me feel comfortable and leave there with a . Highly recommended! read more

The service and care is top notch. They're very flexible with scheduling and their staff is incredibly helpful and friendly.

From the front office, to Dr Ash and Dr Truong, and all staff , it's always a very thorough and professional experience. Their after care concern is exceptional . My recent visit was with dental hygienist Sherry and Dr. Teuong . Sherry and Dr Truong thoroughly explained each step, pausing to see if I had any questions. Any concerns, they addressed immediately. Perfectly painless dentistry !! The entire staff is exceptional and Dr. Truong did a restoration that I absolutely love . read more

I always have a great experience here. They are very friendly and are very quick and efficient. They are always on time and very straightforward. Thx Margo and dr. Truong read more

I have been a patient with Dr Ash and his wonderful team for years - whether front office, hygienist, the docs, or back office -- all are compassionate, kind and welcoming. I started going when I lived in Irvine, but continued to come back when I studied medicine up in NorCal, and now that I'm a practicing physician in LA County, I still make the trek down south! Special shout-out to Dr Ash and all the amazing dental assistants and hygienists. Take it from someone who has moved around their whole life to multiple states/countries... it took FOREVER to find an excellent, non-pushy, comfortable dentistry experience. Highly recommend! -Dani A. read more

BEST dentist and team there is. I have some horror stories of previous places I've gone and Harmony Dentistry has made me not scared of the dentist anymore! From the second you walk in the door, the girls at the desk are so kind and cheery. I came in a few days before my birthday and they had some chocolates for me! I had to get some work done for the first time ever in two separate appointments and I was terrified and so scared of needles. Dr and Sherry were so gentle, understanding, and skilled because I didn't feel a thing! During your appointment you can have a paragon wax treatment on your hand, watch Netflix with headphones, get blankets pillows etc. you're greeted by name and every single person working there is amazing. A few hours after my appointment, the Dr. called me personally after the office was closed to see how I was doing post dental work. I would give them 10 stars out of 5 if I could! read more

I can't say enough great things about Dr. Ash and Sherry, the dental assistant. They completely redefine what a dental visit feels like--in the best way possible. Every appointment feels more like a pampering spa treatment than a typical dental procedure. Dr. Ash is extremely knowledgeable, gentle, and thorough, always taking the time to explain each step before moving forward. What truly sets him apart is the genuine care he shows--even following up after a procedure to check on you. That kind of attentiveness is rare and so appreciated. Sherry is equally amazing--friendly, kind, and professional. She makes you feel at ease the moment you walk in. Together, they create such a welcoming and comfortable atmosphere, I actually look forward to my appointments. I never have to wait long, everything is well-organized, and I always leave feeling like I've had the best possible care. Five stars all the way--highly recommend! read more

Dr Ash and team are awesome! No insurance issues as you will always know up front what you will need to pay. Friendly and they have all the latest tech to treat you. They even gave me a bottle of cider for my birthday ! Thanks Miranda! Highly Recommend! read more

Impeccable office, super friendly and accommodating staff. Love the dentist. Very knowledgeable and professional. My husband and I both love it there. read more

Thank you Dr. Ash and wonderful Harmony Dentistry Team. This office always makes you feel so welcomed and at ease, as well as offer up wonderful service with constant communication throughout it all. I really appreciate all that you do. Thank you again. read more

I had a crown put in. The Dr. Troung called me later that day to check up on me. The dental assistant, Sherry was super helpful and kind. This office has everything! Highly recommend it Russ read more

Harmony Dentistry is it okay! This is the place! I've been going here about 8 years now even after I had moved further from the office. I've had the pleasure of working with Dr Ash, Dr Truong, Natalie, Shamicka, Sherry, Dianne, and Rebecca and they all are phenomenal. Everyone is very personable, polite and professional. I never had any issues with customer service or getting in contact with them on the phone. (i.e. I'm not yelling "Representative!!" A hundred times to an automated phone just to speak to a real person like some places.) I appreciate the modern feel of the office and the fact that you can receive updates and communicate with the team via texting which is really convenient. I've never had a problem with long wait times when I arrive to my appointments. Side note, if you have to get any wisdom teeth or cavities taken care of..You're not leaving until you do and have a perfect and healthy smile, which is a good thing, right? Haha In a nutshell, I would recommend this place. read more

4 years later after my first review, and I still love this place. No matter if I'm getting a regular cleaning or something like a crown or teeth filed (yeah, freaky I know - for my Invisalign trays), I'm not even stressed because I have the utmost confidence and trust that Dr. Ash and his team will do an excellent job. I wholeheartedly recommend them! read more

Dr. Ash is awesome and caring, very focused on patient comfort. he lets you know what he is doing during any all procedures and puts you at ease. office is pleasant and staff are all wonderful. read more

I love coming here!!!! I've had a crown put in by Dr. Ash and two fillings performed by Dr. Truong. Both Drs. Are very attentive and they share with you what they're about to do in each phase and what type of feeling you would be encountering; which help calm your nerves. The best part, they have hand paraffin and blankets should you want them. Harmony Dentistry should really be known as Dental Spa! I've had various dental hygienist here and they're all very good and gentle. The front desk staff are very knowledgeable about billing and know how to explain the coverage. You won't be disappointed! read more

I am beyond grateful for Dr. Truong, Linda, and the entire office staff. I battle awful anxiety from trauma as a kid in a dental chair. They have completely turned my view around and I wouldn't go anywhere else. Even though there was work to be done on my teeth from neglect, not once did they make me feel ashamed or embarrassed. Truly only wanted to help me regain my confidence again. They were so patient during the procedures I've had. Even my deep cleaning was a breeze and I left feeling so happy and confident again. By the way, the team at the front desk are amazing. I've never seen such great service in a medical setting. Can't thank you all enough and I look forward to continuing my treatments with the office. read more

Five-Star Care That Feels Like a Spa -- Without the Pretentiousness From the moment you step into Harmony Dentistry, you feel it -- the name truly matches the experience. Instead of that typical clinical smell, you're welcomed by a calming, spa-like aroma. The staff greet you with genuine warmth, not forced friendliness or snobbish "luxury" vibes like I've encountered at other similar-concept offices. Here, it's real. Everyone is kind, inclusive, and focused on making your visit relaxing -- not exclusive. I first started coming to Harmony Dentistry about eight years ago, shortly after they opened. After just a year of amazing care, I had to move away for work. Now that I'm back in town, returning to Harmony has felt like a homecoming. Many of the same staff are still here, which says a lot -- and my recent visit just reminded me why I stayed loyal to them for so long. During a recent routine cleaning, I was seen by one of their longtime hygienists -- someone who's been there since the beginning -- and she was fantastic, thorough, and kind, just like I remembered. It turned out that a cavity I'd been watching for years finally needed to be addressed. The team made everything so smooth -- no surprise bills, clear communication about what my insurance would cover, and they got me booked in quickly based on my availability. On the day of my procedure, I came in early after a rough work morning, rushing and without breakfast. Despite all that, I was immediately put at ease. They wrapped me in a cozy blanket, gave me a warm paraffin hand treatment, headphones to help me relax -- and I genuinely felt like I was at a spa. Dr. Truong numbed the area with such care that I didn't even feel the shot, thanks to the topical anesthetic he used first. Sherry assisted during the procedure and was such a calm, reassuring presence. Her smile and energy made me feel safe and relaxed the whole time. Dr. Truong was meticulous and kind -- he takes a minimally invasive approach and really focuses on doing what's best for your long-term health. My retainer still fit perfectly afterward, and the numbing wore off exactly when he said it would -- which meant I was able to go back to work and speak clearly, no awkward slurring or over-numbing. And then, to top it all off, Dr. Truong personally called me at the end of the day to check in and make sure I was doing well -- no soreness, no lingering discomfort. That kind of follow-up is so rare and so appreciated. I've seen multiple dentists and staff members at this office over the years, and the care is consistently excellent. They take most insurances, are upfront with costs, and make every effort to reduce anxiety -- whether it's about the procedure itself or about finances. It's truly full-service, compassionate care. Huge thanks to Dr. Truong, Sherry, and the entire Harmony Dentistry team. I honestly can't imagine going anywhere else. read more

My daughter had four extractions performed by Dr. Ash this morning. As soon as we walked in the office, I knew we were in good hands. Dr. Ash and his assistants did everything in their power to make sure my daughter was comfortable during the procedure, easing her worries every step of the way. He even called us at the end of the day to see how she was feeling. Wow! Harmony Dentistry is simply the best! They go above and beyond in every way. read more

This is by far the best dentist office out there!!! If you are looking for a great experience, while getting quality work done, this is the place. Dr Ash is absolutely amazing! The staff are supper friendly as well. You won't regret it!! read more

Just visited again and it's always such a pleasure coming here. Ferreals feels like a spa day each time! I always opt for the free hand paraffin with Netflix and noise canceling headphones. The staff are super friendly and helpful in navigating insurance questions. Highly recommend. read more

As an orthodontist myself, I'm very selective about who I trust with my own teeth. Without a doubt, Dr. Ashkan Haeri is the only dentist I trust to work on me. I confidently refer all of my friends, family, and patients needing comprehensive dental care to Harmony Dentistry. With decades of experience in the dental field, I'm always impressed by how smoothly this office runs and the great care they provide. Let's be honest, no one looks forward to dental work, but the team at Harmony Dentistry really goes above and beyond to make the whole experience as comfortable and pleasant as possible. If you're looking for a dentist in Mission Viejo, I highly recommend them. You won't regret it! read more

I've been here twice now and both experiences were exceptional. This last time the team went above and beyond to help entertain my 1 year old while I got my teeth cleaned. Everyone here is so friendly and caring. Can't recommend enough! read more

Lauren did a great job deep cleaning the left side of my mouth today. I am probably the worst at flossing on the planet so I'm sure it was a bloody mess, but she didn't complain or lecture me at all. She just kept asking me if I was ok...what a sweetheart! I love how they always tap you on the shoulder to distract you while you are getting your oral shot for pain...so considerate. I love this place. read more

Fantastic dentist! They're on time, competent, don't push unnecessary services, give a pain-free cleaning experience, and are quite friendly. I've been going to Harmony Dentistry for the last five years. I specifically go to see Dr. Ash and his assistant Ali. They're both just great. Both so friendly and know what they're doing. Ali is quite efficient at her job, getting you in and out of the office quickly while not making you feel rushed. Special shout-out to the front desk staff too. They're always very friendly and helpful. It's one of those places where I get the impression that the people there genuinely look at it as a nice place to work. read more

Always taken Care of by Natalie, Mirranda, Dr Ash, Dr Throng, Sherry everyone up front and back. They always find room for me incase of emergency and it's just not normal for a dental office and employees to be so upbeat happy and friendly,, I'll take it though. Hopefully their not hitting the gas themselves J/K read more

Well my crown of 11 years had finally cracked :( Good thing I had Sherry by my side for all her wonderful help and care. This is a 5 star Dentistry easy and might possibly be the best in the area. Dr. Troung did a superb job and explained everything bit by bit so that I understood all the procedures. Didn't even feel the numbing shots - what a "Pro". So if any of you are looking for a new Dentist and you want the best give Harmony Dentistry a shot, you will be glad you did! Office staff is friendly and attentive and the best thing is they do accept cash, just make sure it is the exact amount. read more

Had my first visit with after a not so pleasurable with another dentist. Dr. Troung along with all their staff are fantastic. Everything was explained to me up front. The office is clean. They offered me multiple kind gestures to make me feel comfortable. The dentist let me know every time he was about to do something (pinch my cheek, start drilling, splashing water, ect.) and it truly makes a world of difference. Really helps ease the discomfort that comes with patients. It's rather refreshing to be at a dentist who genuinely seems kind, wants to help, and knows what they are doing. Once my work was finished (fillings redone/cavity work), he showed me before and after, asked how I was feeling about the work, and wanted to make sure my teeth/bite were 100% before I left. Not once did I feel pressured or rushed. I strongly recommend Dr. Troung and the staff. I will absolutely come back and recommend the office to the others. read more

Dr Ash and his staff go above and beyond to help you feel comfortable. I deal with a lot of anxiety but I always know I'm in good hands when I'm there. They really care about their patients. read more

Harmony Dentistry - Getting the warm paraffin treatment - Cosmetic Dentists Near Me - Mission Viejo, California

Had my first dental emergency with a cracked crown/root canal and Dr Truong handled everything so smoothly I couldn't believe it. Fit me in within 24 hours, texted me personally, got me a refferal to the endodontist in the building same day and took care of my broken crown all in one day! Miriam is also the sweet hygienist and walked me downstairs to meet the endodontist to do a CT and xray. Truly can't ask for anything more, Dr T also calls all his patients after they have work done. Never leaving this practice! read more
