I've been a long time client of this office. I resisted posting a review about this prior, but owing to the circumstances-- I will. His hygenist BROKE my front tooth during a cleaning. The office tried to deny responsibility. I demanded that he fix the tooth, which he did. He knew it was a result of his employee's lack of care. Fast forward, on a separate occasion, HE HIMSELF promised that cleaning services were covered, as they always have been.....My cleanings have ALWAYS been covered 100 percent--by this dentist's cleanings.....YET I GOT A BILL FOR around 200 dollars. Stay away from this office. Dr. Chien is not an honest person who cares about the wellbeing of his patients. He's a salesman who wants to make money, and if your teeth get repaired in the meantime, that's great. Otherwise, it's about making money. I'm not going to allow this to go unfixed. read more

Always kind, detailed, and professional. I have complete trust in Dr Chien and his staff.

Very friendly and professional staff. Dr. Chien is outgoing and personable. He truly is concerned about his patients and takes time to get to know his patients. Everyone, from the front desk to the hygienist and including Dr. Chien, go above and beyond to ensure that I am comfortable and fully informed of what is happening, what they are doing next and how long the process will take. They truly make me feel like a "VIP". If you are like me, I have always disliked (despised) visiting the dentist. I know it is necessary but I have always thought of a visit as a necessary evil. And, as a result, have often procrastinated...resulting in more pain and expense... These professionals in this office make me reassess my thoughts and impressions of dental visits. I look forward to going. Not only do I leave with clean teeth (a feeling I truly enjoy) and a level of comfort knowing my mouth is healthy - I also leave feeling like I have just received VIP treatment - which I have. Looking for a new dental professional? I highly recommend Dr. Chien and his staff. I believe you will see why I leave feeling like a very confident VIP! read more

It was my first visit with Dr. Stan Chien. It was everything the comments have mentioned from previous patients. I wanted to find someone closer to where I live. He was very professional and I find that he has a "warm" approach with patients. I wanted to leave this review as I know how comments really assist others. I am glad to have made my first visit. His staff was very professional. read more

I am so grateful to have found Dr. Chien! He is so kind and thorough in his work, even with a routine check-up and cleaning. It was a very comfortable experience and I highly recommend him. read more

I have had Dr. Chien as my dentist for the last 15 years. I have had great results there. I have had general dental care and also a couple implants, fillings and crowns. I am a bruxer so have had night guards to prevent that. I myself am an ENT doctor so I am probably very discriminating about dental care. I have always felt safe and well cared for by Dr. Chien and his staff. I recommend him to my friends and also my patients who can go to Irvine. read more

I had my teeth cleaned today and as always I was very pleased with the service/staff. Dr. Stan Chien was extremely knowledgeable & polite. He answered all my questions/concerns and put me at ease. I highly recommend him for your dental needs. read more

I cannot speak highly enough of Dr.Stan Chein and his incredible team. After being told by another dentist that I needed three urgent crowns, and two root canals for the pain which started after I had gotten two crowns by him. I was lucky enough to find Dr. Chein and went in for a second opinion. From the moment I stepped into his office, I knew that I was in good hands. Dr. Chein is not only honest, but also incredibly knowledgeable and experienced. He took the time to thoroughly examine my teeth and develop a treatment plan that was both conservative and effective. Dr. Chein found the true source of my pain, which was bad occlusion of the previous crown that I had gotten. I was amazed by his level of care and attention to detail. He saved my teeth from needing unnecessary root canals and urgent crowns and my pain is completely gone! His gentle and conservative approach to dentistry is truly remarkable, and I felt confident that I was receiving the best possible care. Overall, Dr.Chein is hands down the best dentist I have ever been to, and I would not trust anyone else with my dental care. I highly recommend him to anyone in need of a skilled, honest, and caring dentist. Thank you, Dr. Chein, for everything! read more

I hate going to the dentist. Period. However, Dr. Chien is the best dentist I have ever had! He explains everything to you in detail, is very honest, and gives great advice. He even gives you a call to check on everything, a day after you go in for something big like a tooth ache, crown, etc. That really impressed me since my previous dentists never did that! His staff members are friendly, the office is always clean, and they have nice high-tech equipment. My advice is: if they tell you to floss more, do it. If you need to wear a night guard, do it. If they tell you to come in for cleanings every 4 months instead of 6, do it. They really are trying to help you improve your dental health, and you can avoid making even more trips to the dentist each year! I would definitely recommend Dr. Chien to everyone! read more

Excellent service and patient follow-up. Glad I was able to find a good dentist / hygienist nearby. The hygienist is very nice and takes the time to educate you. Easy to make an appointment, and I had a very short wait time before being seen. read more

I highly recommend Dr. Stan Chien. Great personality and great dentist. He is very knowledgeable and wants to make sure you are taking care of your teeth health before it's too late. Always giving me lots of great tips and I look forward to coming in and getting my teeth clean. Kudos to the staff for the great service and keep up the great work. read more

My first visit was such a nice experience.. Stan the dentist was very attentive and took the time to review everything with me ! I highly recommend them! read more

I highly recommend Dr. Stan Chien. Dr. Chien is professional, knowledgeable and very friendly. The staff is also very accommodating and efficient. Great doctor! Great Team! read more

Been going here for a year. Costs are great, dentist is always friendly, hygienist does their best for me! They are incredibly accommodating with reschedules. I wish I lived in Irvine sooner! read more

I went in for a thorough teeth cleaning, x-ray, and checkup. Dentist Dr. Stan Chien took the time to patiently explain to me of the entire process and answered every one of my questions thoroughly. He went above and beyond what was necessary to make sure I was delighted with my teeth. Unlike most dental receptionists, the receptionist here is really friendly and is incredibly easy to make an appointment with. The office in Irvine, CA, is super clean and modern. From my friends who also go to Dentist Stan Chien, he also does great dental implant work as well. read more

I have been a patient of Dr. Chien since 3-4 years. I have not experienced any thing better than this before. Very clean environment. Very good care for patients. Dr. Chien and his staff are the best team in this area. Flexible, friendly and they treat you like family. I would recommend anyone to go to Dr. Chien for a peaceful dental life. Thank you Dr. Chien for your courtesy and service... As always, With Best Regards, Shoba read more

I visited for a free consultation that turned into an ongoing disaster. Issue #1: I visited due to a 1800 dentist referral that said Dr. Chien was open on Saturday. I showed up, and he was not open. I re-secheduled. Issue #2: Inexperienced staff. Even though I was the only patient, I stilled waited 20 minutes. The assistant didn't know how to use the xray program and tried for another 15 mins. She eventually had to ask Dr. Chien to do them. Dr. Chien then dictated to his assistant and he had to SPELL the words out for her. Red flag. Issue #3: Dr. Chien recommended I get 2 crowns as well as 4 fillings for some issues in my xray. This is not a problem per se, but I got 2 other opinions that I definitely did not need crowns. Not only did I not need the services recommended, I brought my treatment plan from Dr. Chien to the other dentist and they laughed, saying some of the treatment plan didn't make sense. Issue #4: This supposed one time "free" consultation was a SCAM. They charged my insurance company thousands of dollars, claimed I received two crowns. So when I went to another dentist a week later, my insurance denied my claim because I was maxed out by Dr. Chien! This is unacceptable. I work full time and luckily my new dentist submitted all the forms and evidence to my insurance proving I did not receive any treatment from Dr. Chien. But this took several months. I hate to blasts someone's business, but there wasn't one redeemable aspect of my visit. Office hours were unreliable, staff was inexperienced, treatment was questionable, and billing/insurance was a disaster for something that should have been free. read more

Dr. Stan Chien and his team are great! Everyone was very helpful and knowledgeable. Thank you for your professionalism and care!

I went to Dr. Chien for my implant crown consultation. The front desk staff, Marc, has been very helpful. Dr. Chien is a very knowledgeable dentist. He took his time to explain every detail of implant crown to me and answered my questions patiently. I came out of his office and found myself gaining some important information on what to expect when getting an implant crown. I am glad to have visited Dr. Chien ! read more

I've been coming to Dr. Chien for several years now, him and his staff are all fantastic! When I first moved to Orange County, I found Dr. Chien from a web search through my insurance company, I picked him because he graduated from USC, my alma mater, keeping it in the Trojan family! First thing I noticed during my first appointment was his diploma on the wall with a B.S. in BME, my major! what gives? I knew I picked the right dentist at that moment, we even had a few of the same professors! Unlike other dentists I've had where the hygienist does all the cleaning and you never even see the doctor, Dr. Chien always spends time with each of his patients and actually checks your teeth himself. I've always know I grind my teeth, but dentists before never suggested night guards to me. Dr. Chien got me fitted for a night guard right away, I've already ground through 2 of them, it's shocking to see the damage I've been doing to my teeth before the night guard! When there are fees not covered by insurance, they will go over the finances very clearly with you so you know exactly what you're being charges, and it's all legit. When I needed my wisdom teeth removed, Dr. Chien couldn't do it himself and had to refer me to a surgeon, Dr. Vaughan, who was also excellent. Good dentists know other good dentists! Nobody enjoys going to the dentist, but Dr. Chien and his wonderful staff really makes the experience enjoyable. read more

Dr. Chien is knowledgeable, professional, skilled and friendly. He is always patient and explain with you the root cause and care plan. He even called to follows up after each treatment which is really impressive. I had one tooth needs to do crown. When he did the needle numbing my gum, I did not feel pain at all. And after the treatment, he gave me a clear care plan to make it comfortable. Dr. Chien is definitely a trustable dentist. Cleaning service is wonderful. Office is clean and comfortable. His team is friendly and you can have message reminder before appointment. Highly recommended Dr. Chien and his team. read more

I went in with what I thought was a dental emergency, turns out I was just over thinking what my real issue was! The entire team at Dr. Chien's office is amazing. read more

Dr Chien and his staff were great. His office and different rooms I went to were spotlessly clean and they took every precaution to make me feel safe. They were all very professional, friendly,knowledgeable and thorough in their approach to taking care of me. read more

Dr stan his helpful staff and hygienist are a pleasure to work with. I started with Dr stan for my routine cleaning and root canal etc. In all of this the dr and his office have a very patient centric approach and take time explaining the small details regarding my teeth and have helped to gently imbibe good dental practices to keep my teeth healthy. Defntly recommend Dr.stan as your dentist. Will update more once my tooth crowning experience is done. read more

I had moved out of the area for a year and just move back when my wisdom tooth cracked in half. I called the office to see about making an appointment and they got me in the very same day I couldn't believe it! I was concerned whether I would need to have the tooth pulled or get a crown and he spent time with me evaluating the best option for my situation. I couldn't be more happy to come back and have Dr. Chien as my dentist again. No place like home. read more

Dr. Chien has looked after the teeth of me and my family for years. He has always been super attentive to the condition of our teeth and has advised us of potential problems we might face as well as suggested preventive measures to avoid them. Yesterday I went for a temporary crown for a crown that had fallen off. The visit was painless and smooth and I had no problems whatsoever sitting there for 2.5 hours. A special shoutout to Sally who was his assistant in the procedure and was more than an assistant. She not only knew her work very well but was also very understanding and offered a lot of emotional support. I had the best dental experience yesterday thanks to her and Dr. Chien. Thank you Sally for being such a good friend and for being so caring and supportive! read more

I feel truly blessed to have Doctor Stan Chien as my dentist. He is a very positive and competent person. I had a hard time when I was looking for a dentist when I came to Orange County and was referred to Dr. Chien through Dr. Nooshin Ghayoumi who spoke most highly of him. I wanted a second opinion and I was very happy with what he told me that was a year ago now. All the staff are great. I cannot remember everyone's name but I appreciate Sarah, Monica, Carrie, and Angelica among others. He uses the latest equipment including digital X-rays, and often does not charge for dental procedures. He believes in the best dental care which means you may find someone that is less expensive but they will not be as good. He accepts all regular insurances and is very reasonable about pricing for people without insurance. He is very ethical in his referrals and knows how to make people relax. He has moved into a new office which is very modern. If you are afraid of going to the dentist, go to Dr. Stan Chien. read more

Friendly and professional service is what you can expect. They do not try and " sell you extra" which I have experienced in other offices. Highly recommended...... read more

Dr. Chien and Angelica, my hygienist are amazing! I will never go to another dentist. They have a beautiful office and beautiful smiles!

Dr. Chien was my dentist while I was living in California. He is friendly, kind, and professional. My wife and I were very fortunate to have known him and his wonderful staff. The only downside to having such a great dentist is trying to find someone as good as him now that I've moved! read more

Dr. Chien and the staff were very friendly and accommodating. They were very careful and gentle with my sensitive teeth. They gave me some good tips on how to care for my teeth and gums that was lacking at other dental offices. I will definitely keep coming back and recommend his office to others looking for a great dentist and team. read more

Have been going to Dr Stan Chien for many many years now. He's got excellent bedside manner as well as being a skilled, thorough and professional dentist. It's very difficult to find any doctor with that combination! He's always friendly and caring. The office is clean, modern and comfortable as well. read more

I recently saw Dr. Chien for a second opinion. He and his staff were extremely friendly and very thorough. I knew exactly what was going on and never sat alone in the exam room for more than 30 seconds. He was very open and candid about my situation and made me feel important and valued. He answered every question I had, never rushed me and is allowing me to make my own decisions rather than providing a diagnosis as if it was a matter of fact. This is the way that dental care and healthcare, for that matter, should be executed. Having been to larger commercial dental groups, I prefer the attentive care I received at Dr. Chien's office. read more

A great Dr., who is very personable and has great etiquette. I have been to many many dentists and so far he and his office staff are the BEST. If you hate going to the Dentist, (like I do), you will love this place. All the staff are incredibly kind and understanding. My stress level starts to go down once I am in the chair. Monica is a wonderful hygienist and explains everything!! The front office staff make checking in and checking out a breeze. I cannot remember their names but they are very helpful and explain the amount of the bill very clearly, so there are no surprises. Give this place a try, you won't regret it!! read more

I went in to Dr. Chiens as a temporary employee for one day. The minute I walked in the door, he was rude, unprofessional and insulting.Also, he called my agency and complained about something that has never happened before in my entire career. I believe we need more respect and kindness in this world and people of a more mature age contribute allot to our society. In addition, these people are almost always the same age or older, what a hypocrite. read more

Dr. Chien is the best. Friendly, caring and professional. His office is beautiful and his staff is great. If you are looking for a dentist, I highly recommend Dr. Chien. read more

I have always had an aversion to dentists. Dr. Chien has been one of the most enjoyable dentists I've ever had the pleasure of seeing. His staff is awesome, in particular, Angelica and Wendy. They are professional, kind, compassionate and understanding. I would highly recommend his office for dentistry. read more

I am very disappointed with the care I received from Dr. Chien. He claimed to be the type of dentist that works with people who are "dental chickens" but when I saw him he had nothing available to put me at ease. He acted no differently than any other dentist I could have found..He wasn't mean and he didn't torture me but he also didn't go out of his way either. I was playing music with headphones on so I wouldn't have to hear the drill (one of the worst sounds in the world!) and he tapped me on the shoulder and asked me to turn it down because if was too loud and was bothering him! So there I was forced to listen to that drill. Initially he told me he had medication I could take if I got really nervous, when I showed up for my follow up (I had to go because the cap on my front tooth had fallen off and this was the visit to put the new one on) he told me he "couldn't find" the medicine and I should just get through the procedure without it. Needless to say I no longer believed he really understood the concept of a "dental chicken". This visit occurred several years ago but I'm writing my review now because now the gum on my front tooth where he placed the cap is receding and the top of my front teeth no longer look like they match when I see myself in pictures. I've gotten to be very self conscious about my smile and go out of my way to cover my mouth when I laugh and try to smile without showing the top of my teeth in pictures! I spoke with a dentist in the area where I now live and I was told that the receding of that isolated portion of my gum (only on the tooth that Dr. Chien capped!) could have been prevented if he had only told me to massage my gum in that area following the placement of that cap!! Seriously? Why would a good dentist leave something like that out of the aftercare instructions??? There is no way my gum can be fixed without surgery and replacing the cap WON'T do anything!! Does that sound like something a good dentist would do? All of this could have been prevented had Dr. Chien taken a few more minutes to consider the feelings of a "dental chicken".. I wouldn't recommend him if you happen to be one too! Find another dentist who actually cares and will take the time to ensure your smile lasts long after you no longer need him!! Thanks for messing up my smile, Dr.!! read more

Wonderful experience, the staff went out of their way to make me feel comfortable and welcome, they were friendly and professional. Dr. Chien made sure that I was comfortable and in no pain at any time. He was very professional and thorough, he even called me personally the following day to see if I was doing well. Would highly recommend him and his office to anyone that is searching for a great dentist! read more

Dr. Chien and his team are absolutely wonderful, everyone is very helpful and informative, and they're really great at making you feel comfortable. They're great about working with your schedule and budget, which is a big plus for me. I'd highly recommend him to anyone! read more
