Our orthodontist experience has been as stress free as we could have hoped for. All three of my kids had what I would say were.. my husband's side of the family teeth. Our oldest daughter is finished and we are all very happy with her beautiful smile. Our middle daughter had her front teeth growing every which way and over the course of a few months her teeth already started to look amazing. Dr. Peng, Dr. Areepong l, and the entire team are a pleasure to work with. They keep you informed every step of the way, and are absolutely perfectionists. The team that schedules appointments and answers questions are the best. Over the course of a couple years they have always been super friendly and always go the extra mile to help with any issues. I will continue to refer all our friends and coworkers to their practice. read more

Saijai Peng, DDS MSD - Walnut Orthodontics - Orthodontists Near Me - Walnut, California

Okay it's taken me over a year to write a review, but I just wanted to explain how happy I am with the overall result. As an adult, I had braces since October 2020 to January 2023 so a little over two years. At some point in 2021, I moved to Seattle and kept flying back and forth for my treatment. It was a long and difficult journey and I felt insecure having braces as an adult, but overall it was worth the time and money because I feel more confident. From having crowded teeth to becoming more centered, I'm very satisfied. I could have switched to another Orthodontist in WA but I trusted the process -- Dr. Peng, Dr. Areepong and the whole team made me feel comfortable and made it easy when I filed to visit every other month! If you are willing to pay the money and go through the process, I would say go for it and you'd feel so much more confident smiling! Thank you all for the past 2-3 years! :-) read more

See all

At first, I've came to this orthodontist to get the confidence of being able to smile without worrying how my teeth used to look. All of the staff here were really nice especially Daniel, he really looks like he enjoys his job a lot. Both doctors, Dr. Peng and Dr. Areepong are also both very skilled and talented, I still cannot believe how my teeth changed this much thanks to their help. All of the staff were also very approachable so if you have and concerns or any minor question, its always fine to reach out to them! The office for the past 3 years that I've been here have had also been really clean and most of the equipment were always wrapped in a plastic food wrap layer that can ensure your sanitization while being here and all of the small details for each season were also really easy to tell that the staff really had put in a big amount of effort to make the place look inviting. Lastly, I would like to thank again to all the doctors and the staff here, without their contribution, I wouldn't be able to live on confidently with how my teeth looked. Thank you! read more

Staff is so incredibly nice. They heard me out and my case, were very considerate to my needs and fears (came for help with old orthodontics). I feel very comfortable here and that means a lot. You can see the generational trust here. They are who I will be sending my family to for any and all orthodontic needs. I am so very glad my dentist recommended me here. Thank you all read more

Thank you Thank you Thank you Dr Peng, Dr Areepong and their wonderful team for everything. We are so glad that we had decided to bring my son here for his braces. The first time meeting with Dr Peng, she explained clearly step by step her treatment plan for my son. And on the same day, after my son's first appointment, Dr Peng called around 8:00pm to follow up and make sure we understand any possible scenarios that my son might be facing and provide lots of helps. I really appreciated And the staffs, everyone is so friendly and patience, very easy to communicate with in timely manner. Overall, I highly recommend Dr Peng and her staffs If you are still browsing and cannot decide which orthodontist to go to, Dr Peng and Dr Areepong are probably the best out there and they will take good care of you. Thank you again for helping my son, he now has the best smile in the whole world read more

Saijai Peng, DDS MSD - Walnut Orthodontics - Orthodontists Near Me - Walnut, California

Most poor service of a DDS office. She literally said I don't need to understand the process, only need my daughter to understand (14 years old). I said that I need to understand because I'm the mom! Then she refused to service me because I keep asking questions. Then she said my daughter doesn't like me. This is not professional at all. We had conflict with professional issues, then she went personal. read more

So, it's been three and a half years since I had my braces taken off and I continue to maintain my teeth by diligently putting on my retainers every night as Dr. Peng advised me. I went back recently to get them replaced. The warm welcome and care that Dr. Peng, Dr. Areepong and staff had given me were exceptional as expected! It was nice to come back and I believe I will keep coming back! Choosing Dr. Peng and Dr. Areepong for my orthodontic treatment was one of the best decisions I've ever made. People continue to compliment my smile! Again, I highly recommend them! read more

Staff so helpful, good location, plenty of parking. Dr. Peng such a wonderful and knowledgeable Orthodontist. My kids all got treatment by her. read more

Saijai Peng, DDS MSD - Walnut Orthodontics - Lobby of Dr. Peng's office. - Orthodontists Near Me - Walnut, California

I went to Dr. Peng to have my first Ortho treatment back in 2001. She did an amazing job on my first treatment. Over the years I've always been good at wearing my retainers. Even if I would misplace or break them, I always went back to see Dr. Peng. Unfortunately as I got older my snaggletooth started to stick out and it started to bother me. Everyone says my teeth look fine but if you look at the photos, you can clearly see who my problem child is. Initially I wanted to get Invisalign but Dr. Peng suggested that going that route wouldn't get me the results I wanted. The issue was to realign the root of the tooth and Invisalign wouldn't fix that problem. As always, I fully trust Dr. Peng in all her assessments and all her referrals that has anything to do with my teeth. A week before I got my braces off Dr. Peng asked me "Are you happy with your results?" I answered "Aren't you glad I came back to get it fixed?" I can't say enough good things about Dr. Peng and her son, Dr. A, for all the work they put into my treatment. Off topic but when I first started going to Dr. A when I was 21, Dr. A was still in Jr. High and he would be in the office after school doing his homework. Twenty plus years later he's now my doctor=) It's so nice to see that he's following in his mom's footsteps. I absolutely love the staff too. They are so nice, polite and very helpful. Dr. Peng, Dr. A and staff..Thank you for everything. I'm so happy with my results!! I was once referred to Dr. Peng many years ago and surprisingly I have a few other friends that have gone to her too. They all agree that they love you Dr.Peng! I'm definitely going to continue referring anyone who is looking for a Orth to Dr. Peng and Dr. A. Hopefully when my niece and nephew get older they will go to Dr. Peng and Dr. A! read more

This past 3 years a lot has changed with my teeth and I have to Thank you, Dr. Peng, Dr. Areepong, and their incredible staff! This orthodontics makes a huge positive impact on my teeth structure, etc.! Over the past three years, my transformation has been nothing short of remarkable. Completing my braces journey just in time for my graduation day must have been amazing! And let's not forget the amazing staff--everyone is so friendly, patient, and easy to communicate with. Their dedication and care truly make a difference. If you ever need further assistance or have more dental-related questions, don't hesitate to reach out. Dr. Saijai and Dr. Areepong, along with their team! They're undoubtedly committed professionals who genuinely care about their patients' well-being. Thank you for everything! read more

Recommend!!! Finally after 2years(so fast) I took out my braces Cant remember my face before lol . They're so nice all of them always smile:) Thank you everyone read more

Saijai Peng is worst doctor I have ever met. First of all, She charged too much . If you go to different orthodontists, you would be a big surprised by her price . She only care about money , she does not care about patient. She doesn't have professional ethic as a doctor. She shouldn't be a doctor. She should do business in flea market, read more

UNTRUSTWORTHY: $200-300 JUST FOR X-RAYS. (You must pay to receive a quote!!) I came in here for a consultation for braces. My teeth are pretty straight but I've got underbite tendencies. Simple right? Apparently not. Here's what gets people to think this is a good place. She pulls out a ruler during the consultation. It seems thorough, it seems methodical. But here's the kicker: they won't be up front with the price quote or estimated cost for braces UNTIL you pay $200-300 for x-rays. I've been to around 10 orthodontists to find the right place and fit for me. But NEVER have I ever had to pay such a large price just to hear a rough estimate. Who in their right mind would pay so much just to get a quote for something they potentially might not even be able to afford?! Look for a better place that won't risk you throwing away your money for nothing. They don't budge, and they are very snakey with the way they handle consultations. read more

This place is THE BEST. Hands down the best place you can go to for braces. The staff here is amazing. They are so nice and personable. I came back here after 14 years of having my braces removed and they still remembered me and my family! They were so excited to see me and hear updates on my life. You're not just a patient here, they truly treat you like family. Dr. Peng is always professional and happy. Diane remembers every patient she ever sees, even small details! I talked to Daniel many times over the phone and he was super helpful. He really helped work around my busy schedule so I can get an appointment. Go here now! read more

We were traveling here from N. CA visiting family and my daughter's wire popped out from her top braces. Dr. Peng and his staff were super friendly and kind to squeeze her in the morning between patients to adjust and fix the wire. We appreciate it so much! Thank you! read more

This has taken me quite a while to write due to my huge disappointment and hurt and wanted to make sure I didn't write super angry. We have been going to Dr. Peng for many years. My 33 year old got braces from her when he was a teenager and I did as well years ago prior to my surgery. Fast forward I had taken in my youngest and I was set on braces as he was a teenager and so on. I voiced this to Dr. Peng and she convinced my son to go with Invisalign after discussing with her even after work hours that it was not a good idea she pressed it and finally gave in, going completely against my gut and better judgement. A few months later, SHE decided that braces were a better idea and we would need to go with braces, ON MY DOLLAR. I was upset, shocked not to mention let down. My son used the Invisalign continuously as initially pressured into, and as my son had some personal issues going on which I had explained to Dr. Peng, we made it in sometime later. Dr. Peng decided while I sat chairside by my son, to basically chew my son out, basically reprimanding him in front of patients and staff. I had to stop her and told her that if she needed to talk about anything specific we needed to do it in her office in private and not announcing her negativity amongst everyone. We returned for a follow up visit, this time I did not go in with my son. Shortly there after he walked out upset stating he wanted to get out of there and get my money back, as apparently Dr. Peng decided to reprimand him again in front of everyone again. He is a tough kid and basically teared up on the ride home very upset. I am hurt, angry and the trust I had for her for so many years is gone. Be better! I'm a nurse and I do my best to treat my patients with respect and understanding. Money should never be a factor and also treating others as you or you would like your family to be treated. Never again and I hope she looks back on this some day and recognize how wrong this was. read more

Just finished treatment recently and straightened my teeth. Best care team ever for all your orthodontic needs! Dr. Peng and Dr. A and team are highly skilled, professional, and experienced! They are simply wonderful and I highly recommend them. Thank you again for everything! read more

I have been grinding my teeth for 30 + years and I had developed a sizable gap in my front teeth. Dr. Peng was so positive and certain that she could address my many problems and I couldn't have placed my trust in a better person. She carefully guided my teeth into a perfect position and I now have a beautiful smile and wonderful dental health. I'm in my 60s and I just assumed that I would have an incomplete smile for the rest of life, but that's not the case due to Dr. Peng and Dr. Areepong. I couldn't recommend their services any higher. They are the best! read more

Thank you Dr. Peng, Dr. Areeponng and your lovely, hardworking staff for being patient with me throughout my braces journey! When I first made my consult, Dr. Peng and her team explained to me the whole process of getting my braces. After waiting a week for my XRays and teeth mold, Dr. Peng sat me down in her office and schooled me on how she's going to transform my smile. She tediously explained the process down to a science and that's when I knew that I picked the right doctors and team to work on my adult teeth. I've had braces when I was a tween, but because I didn't wear my retainers, and because according to Dr. Peng I had what's called a slight "bimaxillary protrusion," I didn't have the straight teeth I had wanted for so long. Dr. Peng is not just any other orthodontist. She explains what's wrong with your teeth, how she wants to fix it angle by angle, and tells you what to expect. I had thought I would be done by my 2 year mark, but because Dr. Peng and Dr. Areepong wants me to have the best smile, they extended me for another 2 months to make sure that every nano inch of my smile is up to their standard of perfection. I appreciate this very much and although I was dying to have them taken off sooner, it was worth it. I am definitely recommending their team to my co-workers, friends and family if I already haven't! :) read more

Saijai Peng, DDS MSD - Walnut Orthodontics - Orthodontists Near Me - Walnut, California

Had a initial consultation with Dr. Peng, she pointed out that my son has big tonsils and must be looked at first. She said that his airway concern is more important than straight out the teeth. She explained everything in detail. read more

Dr. Peng and her whole staff has been such a pleasure to work with. My daughter's case was a little more complex than others and she walked us through the whole process. At first we were skeptic on some of the ideas she was suggesting but because we put our trust in her, the outcome was perfect! Thank you Dr. Peng for your expertise and Thank you to the friendly and caring staff! I would definitely recommend Dr. Peng to anyone young or old who wants to look great and feel great about their teeth. Once agin, THANK YOU Dr. Peng and staff!! read more

My first visit to Dr. Peng was about 15 years ago at least. Now I am back to get new retainers since they are old and my teeth shifted a bit since I don't wear my retainers all the time. Nonetheless, Dr. Peng is the place to get your braces and retainers. Thank you to Diane for amazing service and just being such a sweetheart! You can count on Dr. Peng's services anytime in your life- whether it be when you are 10 years old or now 30 years old! read more

I originally saw Dr. Peng when I was in 6th grade. At the time I had a gap between my two front teeth, some of my teeth were crooked, and I had a serious over bite. Within a year and a half my braces were off, all of my issues were fixed and for the rest of my life I've had a smile that everyone compliments. At the time my braces were removed she added a "spacer" behind my two front teeth to ensure they always stayed together. After 13 years it broke off and I hesitated to get it replaced. Now 2 more years have gone by and I recently discovered that my gap is starting to return! I called Dr. Peng's office and was delighted when I went in for my appointment this weekend. Keep in mind I have not seen her for 15 years and she remembered me! It felt like a blast from the past being in their office once again. She informed me of all the details that putting in a permanent retainer behind my two front teeth would entail, she gave me honest and reasonable pricing, and she performed the task quick and efficiently. All of the staff was extremely helpful and friendly, the gap between my front teeth was instantly closed and I haven't experienced any pain whatsoever. I can't thank this orthodontist clinic enough! Dr. Peng, you're truly a star! I appreciate all of your wisdom and knowledge, you are a master of your profession! If you are trying to decided where to take your child... look no further, this orthodontist is the one for you and your family! read more

Dr. Peng and Dr. Areepong are simply the best! Both doctors utilize the most current up to date technology in their office. After consulting with a few other offices, I knew I was in great hands with Dr. Peng and Dr. Areepong. I LOVE my new smile and I would not have been able to get such a great outcome without their help. I highly recommend their office and their team! read more

Dr. Peng is such a wonderful, caring and friendly orthodontist. About four months ago, I just finished my second round of braces.. both with Dr. Peng! The reason why I had to do it again is in no way Dr. Peng's fault. I had gotten braces as a teenager. A combination of not getting my wisdom teeth pulled out and not properly wearing my retainers had made my teeth move and so I wanted to do it again. This time, I had my wisdom teeth removed first, then slapped on the braces, and now wearing my retainers ALL the time (I actually heard that most people need to continue wearing their retainers for life, if they want to keep their teeth the same). Anyhow, Dr. Peng only has the patient's needs in mind. She is a perfectionist and that is a good thing, when you are spending thousands of dollars on your smile. Everyone else in the office is just as nice, and always have a friendly smile, asks how you are doing, and genuinely care about you and your needs. Calling them, and requesting for more rubber bands is no problem (they send them to your house, too so you don't need to go in the office). I've bothered them a number of times, when I had an emergency wire sticking out or popping out, or something scratching my mouth.. They always allow me to come in as soon as possible and fix it right away. Dr. Peng also utilizes the latest technology and techniques to speed up the process, without improvising the effectiveness of braces. 1st time: 2 years, 2nd time: 1.5 years. She's really great!! When I got my retainers, she recommended that I can get clear, invisalign-like retainers to wear during the day, and to wear the wire retainers at night while I sleep. This is suuuch a big help because I was done with looking like a nerd. read more

This is the first time I ever write a review in yelp,I just took my son for a first consultation with Dr. Peng today, I'm sure Dr. Peng is a experience doctor, after all, she has been practice her dental work in Walnut for a long time, however, my experience with her was not good, she can be rude after she found out I will get a 2nd opinion, I feel terrible when I left her office. A advise for Dr. Peng, you are not just selling your dental work, you have to sell your customer service too, I'm afraid committe two years dental relationship with you.... P.S Dr.Peng, you staff are much friendly than you! read more

To Lou T. and Karl K. This is to respond to Lou T. and Karl K. both review respond to my negative review. Yes, I have bad experience with Dr. Peng. It was worse than negative. To your suprise and to my surprise too. Well, if you think just because you have been treated right then that means nobodyelse could possiblly unhappy with Dr.Peng. I wish you were correct. Because when I paid more than $4000 for first phase treatment for my son I was happily expecting to be treated right as costomer. and all my intention was assist her to help my son going through the tough process. To all the people who are happy with Dr.Peng. Congradulation! I was hoping that happen to me too.unfortunitely it didn't and I do not walk into that door commit to one-year-treatment to looking for bad experience. And just like you have rights to express your good experiece doesn't mean you have rights to question other people's bad experience. we, who had bad experience in this clinic have rights to tell how we feel too. To Lou T, Do not judge other people when you are not there when things happened. mind your own experience. Dr.Peng did apologize to me at our final meeting. so I applause for that. I am still looking for possible way to find justice.... read more

Dr. Peng and her staff are great! I'm so glad that I was referred to her office because I probably wouldn't have known about it otherwise. I had braces for 2 years when I was in middle school and my previous orthodontist had warned me that my jaw will grow into an underbite and that I'd have to get surgery once it's fully grown. That's great that he informed me, but he didn't do too much else to prepare me. Dr. Peng, on the otherhand, is extremely experienced with dealing with underbite cases. When she receives pre-teen patients who she knows will have jaw issues, she gives detailed information about what to expect and prepares their teeth ahead of time. When the patient returns in their late teens/early 20's, all they have to do is put on braces for a couple months, go into surgery, and do some fine tuning afterwards (approx 6 mo process +/- depending on the case). However, in my situation, my previous orthodontist didn't really do any of that, so my process will take 18mo-2yrs. Gah! Dr. Peng and her staff have been extremely helpful, polite, and knowledgeable throughout the process so far. After my first couple visits, I had my mold and x-rays completed. They even advised me that I can take all my records and consult with other orthodontists before I sign anything, which I think shows good ethics and real professionalism. However, after sitting with Dr. Peng for my first consultation, I knew that I didn't have to meet with any other orthodontists. She was extremely detailed in explaining my situation and provided me a couple options to choose from, was honest about what the results will look like for each, and provided her recommendation. Dr. Peng has been very considerate of my schedule constraints and was able to squeeze me in last minute. Everyone in her office is very friendly, professional, and truthful, which are all things that I can respect. The only thing they don't have in their office is the capabililty to do xrays. They refer you to an office in west covina. I have no worries about how my results will turn out thanks to Dr. Peng! read more

Dr. Peng is an AMAZING orthodontist! All these reviews are correct in what they say - her staff truly is amazing and they are always warm and welcoming. Dr Peng herself is very good at explaining the treatment process to you, and as soon as you have any questions or concerns, she is willing to stop and and patiently explain everything so you, as a patient, have full understanding of what she is doing. For me, it was my second time having braces. I had braces before, but was still left with an underbite that went untreated. My old orthodontist didn't explain the process fully enough to me, and I was left unsatisfied with my smile because all he did was straighten it and my jaw was still obviously unaligned. I felt super self conscious in pictures and I even started smiling differently and at specific angles to try and hide it. However, around the end of high school, I finally decided to consider surgery as an option, and having heard that many of my friends went to Dr. Peng for their orthodontics (and still had amazingly straight teeth) we went in for a consultation and were amazed by how professional she was and how she carefully explained my situation to me and what my options were. There was no pressure at all to start immediately, either! I'm extremely glad that I decided to get braces all over again because this experience has made it worth it! Dr. Peng found a way to make the surgery much more affordable for us, and now that I just got my braces removed, I absolutely love my new smile. She was absolutely wonderful and extremely accommodating throughout the entire 2.5 years, so much that even though I'm currently attending college in Northern California, I've been flying back on weekends the last two years to make my appointments. In return, she has been accommodating in scheduling me in! Throught the treatment process there were so many nice personal touches that made the experience very personalized. If you're thinking about getting braces, and still have doubts, I strongly recommend that you go in for a consultation and see for yourself how professional and friendly she is! You won't regret it (: read more

I just recently gotten my braces off and I highly recommend Dr. Peng, her staff are always very friendly and knowledgeable. Not only do they specialize in dealing with under-bite cases (as mine was) but they also use state of the art orthodontic techniques and device on their patients. This was my second time getting braces and the first time was a bust because the dentist really did not know how to deal with my problem and mistreated the problem. Dr. Peng took one look at my case and knew right away how to treat the problem and explained the treatment options in detail. If you have an under-bite case then i strongly recommend you go see Dr. Peng for consultation. read more

Even though I wasn't the easiest patient to work with, Dr. Peng and company were able to do a terrific job in fixing the alignment of my teeth to a point where I am actually happy to smile! Thanks for everything and I fully recommend to anyone looking to make their smile perfect! read more

This place is amazing! All the staff is awesome and very nice. Dr Peng is really professional and knows what she's doing. I know lots of people are afraid of those orthodontists who would just suck your money out of your pocket and have you stick around as long as possible, but definitely not this place. You can come in, get your braces, and take them off as soon as you can. They make sure you get the best smile from this place. Love it! Recommend to everyone! read more

Glad to know Dr Peng and have her take care of my kid's teeth. Her professionalism and clear communication is great.

This place is full of amazing staffs and skillful doctors. I came to this place two years with underbite condition. Every time I smiled I was worried about my smile. That made my look nervous and unfriendly the whole time. Now I'm walking out with brightest smile I've ever had in my life. All my family and friends said I've changed! Of course my smile now is perfect! And I smile confidentially every time now :)) Thanks to Dr.Peng, Diane, Sara and all their staffs. read more

Dr. Peng is a wonderful orthodontist and her staff is just as great. She does an amazing job at informing the patients (and their parents) on the procedures she's going to perform before she proceeds with the treatment. Not only does she explain thoroughly, but she makes sure that the patient is 100% comfortable with proceeding. If not, she will give alternative options and allow the patient to choose which one he/she is most comfortable with. Dr. Peng and her staff are very caring, welcoming, and definitely make me feel like family. I have referred many people to have orthodontic treatment with Dr. Peng, and will continue doing so. read more

Dr. Peng is absolutely wonderful!!! We have known Dr. Peng for a few years now when I walked in to take a look at me but she noticed my daughter's overbite. She suggested that we start working on my daughter right away to get her overbite corrected since she was still at a tender age to have it corrected. My daughter now has perfect teeth with the most beautiful smile! She has also been amazing working on my teeth. Dr. Peng is the nicest and most patient Doctor, we are very blessed to have found her. Dr. Peng already has a vast experience in her field but she continues to educate herself and her staff to learn about new methodology and technology to help her patients in the best way possible. Dr. Peng has the best team on her staff. They always greet you with a smile and they make you feel very welcome. Once again, thank you so much Dr. Peng for caring so much for your patients and giving us such beautiful SMILES. With much appreciation, The Rivera Family. read more

DR. PENG IS A MIRACLE WORKER! I'm 60 years old and because of my daughter's upcoming wedding I wanted to fix my teeth. I gave Dr. Peng literally 7 months to do what others considered ot be an impossible mission and she delivered! Now my teeth are very straight and nice. Thank you very much Dr. Peng, also shoutouts to Sara, Laura and Diana, they are just wonderful! So for those "old" people out there, it's never too late to have great teeth! read more

Thank you so much for your hard work! Looking back two years ago, I didn't know how to laugh or smile. I viewed fixing teeth as unnecessary and painful. I thought removing teeth was inevitable so I tried to avoid fixing it. But with your knowledge and wisdom, you made the journey less painful for me. You knew how to straighten my teeth without removing any! With my parents' encouragement, I made the right choice by giving it a go. Now, my teeth looks perfect, and my smile is bright and presentable, thanks to your group. read more

Dr.Peng was my orthodontist 30 years ago and I am now a pediatric dentist and I always get compliments on my smile! My case was not easy, my results were dramatic and have been very stable. My brother and I's cases were difficult enough that they were used as part of her board certification process. Dr.Peng took in to account my facial aesthetics and profile-I don't have a sunken lower face that is common with results of ortho from that time. Throughout my training, I came to realize how lucky I was to have her as an orthodontist as she is meticulous and dedicated to her profession. Dr.Peng is also a clinical instructor at USC and I know that many orthodontists consult with her on difficult cases. I am also sure that she holds her son, Dr.A, to the highest standard! read more
