Roujin C.

Came here on a friend's recommendation for Invisalign totally worth the drive to San Gabriel :) The whole place feels super comfortable, and everyone is so friendly that my usual "dentist anxiety" just... disappeared. They walked me through the Invisalign process step by step with super clear explanations, no rushing, no pressure, just honest answers. Loved how they used all this advanced tech to show a 3D preview of my teeth - kinda cool and low‑key mind‑blowing. Overall super professional but still warm and chill. Strongly recommend if you're thinking about straightening your teeth!

I was recommended this orthodontist by our dentist. The office is super comfortable and really kids friendly. Maria from the front desk has been very helpful making my appointments and explaining my plan. The doctor is incredibly patient and uses advanced technology, but explains everything in super clear, simple terms so we know exactly what's going on. Overall feels professional but cozy at the same time. Strongly recommend if you're starting braces and want a place that treats you like family!

A friend recommended this ortho office on Huntington Dr and wow, so glad we came! Super kids friendly -- my daughter actually looks forward to her braces checkups, which is wild lol. The office feels really comfortable, staff is genuinely friendly, and the doctor is sooo patient. They use advanced technologies for both braces and Invisalign and always give a clear explanation of every step, no rush, no pressure. I'm doing Invisalign myself and already seeing great results and a more beautiful smile :) Honestly feels like they really care, not just about teeth but about the whole experience. Strongly recommend!

My daughter came for a follow-up visit after school. The doctor's meticulous care and professional expertise every time. The staff are also wonderful--highly recommended!!

Not only is the MD amazing and friendly, but his staff is very welcoming, friendly and attentive. The office was clean, updated and you can see all the new technologies. What I liked most is the doctor was very straight forward and gave me his personal opinion as if I was his family. He was the only MD that was willing to save my sons adult tooth without any extractions and that's why I'm excited my son gets to start this ortho journey with such a great doctor.

I see why this office has a perfect 5-star rating. I'm happy to add another one. If I could, I'd…read moregive them 10 stars! Dr. Luu is one of the kindest, most professional, and gentlest doctors we've ever met. We signed our treatment contract in August 2024, and every part of the process met or exceeded our expectations. My daughter, Jasmine, would frequently come home with extra rubber bands and other little items she needed, and we were never charged extra or surprised with unexpected fees or add-ons. My daughter just had her braces removed, and the results are fantastic! We had been a little worried about possible discoloration after treatment, but there was none at all. Her smile looks beautiful. Looking back, the only thing I wish we had done differently was purchasing the extra set of retainers at the discounted rate they offered. We decided not to at the time, but if you're given that option, I'd recommend taking it--it's nice to have a spare set just in case. Wonderful service, an amazing doctor, friendly staff, and a truly positive experience from start to finish. I wholeheartedly recommend Dr. Luu to anyone looking for an orthodontist. Dr. Luu, thank you so very much for everything. We are so grateful to have had you as our orthodontist throughout Jasmine's teeth-straightening journey. It has been an absolute pleasure, and we will always remember your kindness, professionalism, and wonderful care. We wish you and your entire team all the very best!

My dentist actually recommended Primrose Orthodontics, so here starts my little self-care journey (teeth edition). Dr. Luu and team were great from the very start, from scheduling to actual care. I was ready to drop a pretty penny that was just hanging out in my HSA, but Dr. Luu was transparent and offered me a lot of options and actually recommended I go with the faster and less expensive option since I just needed refinement. Beyond excellent patient care and prompt communication, prices are affordable and I felt like the team spent a lot of time making sure all my questions were answered. They were even accommodating when I told them I had to move some stuff around my HSA before proceeding. Anyway, I'm 6-7 (ayyy) months in, my teeth are straight, and I'm wearing clear retainers over a new smile. 10/10 would absolutely recommend them! Thanks Dr. Luu & co.!

My 9 year old son has been seeing Dr. Wong for over a year after we found out he had a cyst on his upper gum and needed surgery before starting braces. We had a difficult time finding the right surgeon, but Dr. Wong guided us through the entire process and made us feel confident every step of the way. He referred us to an excellent specialist for the surgery, and everything went smoothly. We are very grateful for his care, knowledge, and support. The entire team is wonderful. The nurses and staff are always friendly, caring, and professional. Appointments are always on time, and we never have to wait. We highly recommend Dr. Wong to any family looking for a caring and trustworthy orthodontist. Thank you for taking such great care of our son!

Before beginning treatment, I spent a great deal of time researching orthodontists because I wanted to make sure I chose someone who would provide the best possible results. Choosing Dr. Wong was the best decision I could have made. From the very beginning, Dr. Wong took the time to explain every step of the process and always made sure I understood my progress. At every appointment, he was professional, encouraging, and genuinely cared about making sure I felt comfortable and supported. His positive attitude and attention to detail gave me confidence throughout my entire treatment. Today, my braces finally came off, and I could not be happier with the results. Seeing my new smile for the first time was an incredible moment. My teeth are beautifully straight, and honestly, I could hardly believe the person looking back at me in the mirror was me. I am truly grateful to Dr. Wong and his entire staff for their kindness, professionalism, and dedication. They made this experience a positive one from start to finish. Thank you, Dr. Wong, for everything. You and your team are simply the best. I highly recommend your office to anyone looking for exceptional orthodontic care.

After months of frustration dealing with this dental office, I feel other parents should be aware…read moreof my experience. My dental insurance has a $2,000 yearly maximum, so I am very careful about treatment costs and insurance usage. When I scheduled my son's appointment on March 5, I clearly stated that I did NOT want a cleaning. Despite that, the office still performed one. Since everything had already been started, I did not stop them. I was also told to wait for insurance pre-approval before proceeding with treatment. Later, I was shocked to see my insurance paid $620 for a check-up, child cleaning, fluoride, and 5 X-rays. The claim was processed on March 10. I followed up several times on 3/13, 3/16, and 3/18 requesting the treatment plan and pre-estimate because I had already confirmed with my insurance that the claim had processed. I finally received a response on 3/27. The office manager, Jenny, presented two treatment options with large upfront deposits because pre estimated come back $0. However, I only wanted my son's two front baby teeth extracted. Jenny told me I needed to pay a $300 deposit for extracting teeth O and P. I specifically asked twice whether the deposit would be refunded if insurance paid more than expected, and she confirmed it would. At no point was a deductible mentioned. I scheduled the extraction for April 2 and paid the $300 deposit. Insurance later paid the office $412.80 for that visit. On April 20, I called to follow up and informed them the insurance claim had already been paid and that I had resolved the previous pre-estimate issue. The front desk told me the $300 would be refunded once they received the insurance payment and that they would resubmit the pre-estimate. I called again on May 7 and was told the pre-estimate had finally been approved and Jenny would call me back the next day. After waiting two more weekends without a response, I called again on May 18. During that call, Jenny first said they would refund the $300 deposit but keep $100 for a deductible that had never previously been explained. She then discussed another treatment plan involving teeth L, S, K, and T and demanded a $1,430 deposit upfront without clearly explaining: * how much insurance would cover * which charges applied to which teeth I specifically asked about tooth #S because the dentist had previously recommended extraction due to my child's discomfort. Jenny shifted the discussion toward fillings and said the treatment depended on the dentist's preference to complete multiple teeth in one visit so my child would not need anesthesia twice. However, the explanation was confusing because the teeth L and S she mentioned were on opposite sides of the mouth. I then asked a simple question: if tooth #S was extracted and there was bleeding, could the dentist still perform a filling on adjacent tooth #T? She could not answer. Instead, she said extracting tooth #S would require a $150 deposit. I asked: "If insurance pays more than $150, will I get refunded?" Her response was: "It depends on how insurance pays." I then asked: "How much does insurance need to pay for me to receive a refund?" Again, she could not answer. What concerned me most was that she said she had worked there for 39 years, yet still could not explain the cost of a simple extraction or how refunds were determined. At that point, she said they would only refund $200 from my original $300 deposit because they were keeping $100 for the deductible, then told me to "go to another dentist because they couldn't answer my questions" before hanging up on me. I later went to the office to pick up my $200 refund check and copies of the X-rays. I attempted to speak directly with the doctor to clarify the treatment plan and costs, but another dentist, possibly the owner, instructed the office manager to simply hand me a treatment plan dated March 5. After months of follow-up calls, insurance delays, confusion regarding deposits and refunds, and constantly changing explanations, I was ultimately handed the same treatment plan created on the first visit -- without any updated cost breakdown or finalized insurance estimate. Insurance covered $1,032.38 and I paid $100 out of pocket, making the total $1,132.38 for a child's cleaning, check-up, fluoride, 5 X-rays, and extraction of two baby teeth. Others can decide for themselves whether that seems reasonable. As a parent, I understand dental work can be expensive and insurance can be complicated. However, patients deserve clear communication, transparency about costs, honest explanations regarding deposits and insurance payments, and respectful treatment when asking reasonable questions. Unfortunately, that was not my experience here.

I remember when he pulled one of my teeth out in our early sessions and said: "I'm not going to lie. This will hurt a little bit." I was in 6th grade at that time. Before seeing Dr. Niu, my prior orthodontists had often lied about pain level and claimed nothing would hurt. Dr.Niu is honest and direct with patients. You can tell he does this line of work because he genuinely loves it. He won't try to overcharge you for unnecessary services. Instead, he'll tell you exactly what you need and work on your teeth diligently. Thanks to his careful planning and excellent treatment, I won't need to pull my wisdom teeth out. He's great with kids and adults. When I have kids one day, I'll bring them to Dr. Niu's office. Would highly recommend!
