Check out what some of our happy patients are saying about us:

Dr. Nguyen is truly an artist and a stand out in his field. From start to finish he treats each patient with a critical eye for detail while keeping their best interests at heart. With an engineering background he brings that experience only enhances his attention to detail. Dr. Nguyen  I had retainers as a child for many years and each time my parents tried to get me braces they were told I didn’t need them. We were repeatedly told I had a small mouth and retainers would do the job. As an adult I began chipping teeth and until my dentist refused to repair them one more time until my bite was repaired did I finally agree to meet my angel, Dr, Nguyen!! I wish I had visited him years prior! His staff makes you feel like family and many have become lifelong friends! The office is always impeccable and comfortable. Both Dr. Nguyen and his staff walk you through every step they perform. Unlike many other Orthodonists there are NO hidden costs and everything is all inclusive. Your retainers after your braces, all appointments while the braces are on and the follow-up appointments after!! I highly recommend both Dr. Nguyen and his entire staff!!!!

Dr. Nguyen and his team run a wonderful orthodontics office. The treatment plan for my son is holistic. Staff is courteous. Dr. Nguyen and his assistants explain procedures thoroughly to us to ensure that we are comfortable about the treatment. In occasional cases when we need emergency visits, we were accommodated promptly. Cost is reasonable, and the payment schedule is flexible to work with my FSA plan. I will not hesitate to recommend Dr. Nguyen and his office to anyone for the excellent service provided.

This was my second time having braces. I absolutely recommend Dr. Nguyen, he is an amazing orthodontist. My first time was when I was 13 years old and then when I was in my 50’s!! I just got them off last year and I am going to miss Dr. Nguyen’s office staff. They are wonderful!!! Dr Nguyen is so easy to talk to and he always made me feel comfortable no matter what kind of questions I had for him. I recommend Dr. Nguyen and his wonderful office staff to everyone.

Edna Y. from Laguna Beach, CA (Source: Yelp)


Our twins have been going to Dr. Nguyen the last few months.  They absolutely love him and his team of wonderful staff.  We have researched around for the right orthodontist for our twins for awhile and even though Dr. Nguyen is not located directly in our city, his overwhelming reviews from the social media and high endorsements from other dentists prompted us to have a consultation with him and his team.  We immediately felt comfortable with his knowledge and his willingness to spend as long as needed to thoroughly explain to all of us each time.  Dr. Nguyen and his staff sincerely care about all of their patients and take special care to make every one feel incredible.  We are looking forward to seeing the bright beautiful smiles our girls soon to have at the end of the process.  We would highly recommend Dr. Nguyen’s practice to all of our friends and family!

Expect the best from Dr. Nguyen and his staff. I would highly recommend him. Professional, highly skilled and personable. He can handle the most extreme cases. I couldn’t bite down correctly to chew. I’m now able to eat without any issues and further issues that would have occurred have been put to rest. The entire staff makes you feel at home. A big thank you to everyone there

Eric H. from Laguna Niguel, CA (Source: Yelp)


Excellent!  Dr. Nguyen is very professional and very smart and kind.  I love how he speaks to my kids directly and gains a relationship with them individually.  Both of my boys needed their bite corrected.  One of the underbites was very significant and Dr. Nguyen succeeded without major intrusiveness.  I love supporting a local business and a family who who is very invested and active in making our community a better place.

Janet M. from San Juan Capistrano, CA (Source: Yelp)


We went to Dr.Nguyen for both my daughter Riley and my son Cooper and you should see their bright and beautiful smiles! They are both in high school now and we couldn’t be happier with the results we got from getting braces for both kids at Dr.Nguyen’s practice. Not only did he do a great job, he also took the time to explain what he was doing every step of the way. We especially liked the monitor where we could see the kids progress with the photos he took. He was also very careful not to take their braced off too early which us as parents appreciated.. (our kids were eager to get those things off!). And I would be remiss if I didn’t mention his wonderful team. I love them!! Every time I called..and I called a lot, they were cheerful, patient, and helpful. In addition, they run that office so well that we never had to wait when we got there.. ( once in 2 years, I think when they had an emergency ) and that is so refreshing!! Thank you to everyone for making our experience the best!

I can’t say enough about Dr Nguyen and the staff. Everyone has been so professional and kind. From the moment we walked in the staff treated us like we have been friends for years, it was so refreshing. The way Dr. Nguyen treated my son was as though he was the most important patient he had ever had. I am confident in his expertise and plan for my son’s mouth. My son is so happy that after 2 other consultations with different orthodontists we are now working with the team at Dr. Nguyen’s office.

Our experience with Dr. Nguyen and his staff has been wonderful. They are thorough and quick with each appointment. I am usually there with all 4 of my children and they make a point to include them all in each appointment. I feel we have been given an honest professional opinion and evaluation, and my daughter had a good experience with her braces and retainers.

J. from Temecula, CA (Source: Yelp)


Dr. Nguyen and staff are amazing! Dr. William Nguyen is a serious artist. He takes every case to perfection. His team is knowledgeable, hospitable, great chair-side manners, gentle, easy appointment scheduling, understanding when you have to cancel, easy financing and a just an all around painless experience. There are so many orthodontia choices in South Orange County but I know I made the right one with this office. Without hesitation, I highly recommend Dr. Nguyen and his team!

Exceptional service and beautiful results. I just completed my Invisalign treatment. Dr. Nguyen is a caring, talented professional who uses his background in engineering, the latest advances in the field and his considerable experience to customize your individual treatment plan. I am so pleased with my new and improved smile. He is a perfectionist and it shows in the outcome. Thank you Dr Nguyen and your wonderful, highly professional staff!

Both my daughters have had the wonderful experience of having Dr Nguyen as their Orthodontist. Nurse Debbie was always so friendly and interested in what my girls were participating in. Nora at the front was always so happy and sweet. The entire staff was happy and positive – a fantastic experience and Highly recommended

Ron S. from Dana Point, CA (Source: Yelp)


If you’re looking for an orthodontist that genuinely cares for the smiles and overall health of your children, you MUST choose Dr. Nguyen and his excellent team of professionals. Dr. Nguyen is an orthodontic genius and a genuinely caring and nice person especially to the kids he helps. And most important, our son’s teeth and smile are beautiful. And if the thought of financing a beautiful smile is daunting, don’t worry as they will willingly work with you. He is board certified and his staff are equally kind, nice, and experts at what they do.

Jennifer Basilio (Source: Google)


Dr. Nguyen and staff are great! We have been patients of theirs for 4 years between 2 children. They are gentle, explain well and in easy to understand language, and always check-in with you after the longer sessions. In emergency situations, they are always very willing to work you into the schedule or even meet you after hours. We are very proud to refer Dr. Nguyen to our friends & family.

Rachel J. from Laguna Niguel, CA (Source: Yelp)


I can’t speak highly enough about this group!  Dr. Nguyen and his staff are always a pleasure to work with and they really go above and beyond to help get you through the process.  Getting my son setup with braces was easy and I was able to work out an affordable payment plan to cover costs since we didn’t have an insurance plan to pay for it.  When we had a slight emergency after hours, Dr. Nguyen had no issue meeting us at the office to fix the problem WITHOUT any additional costs or fee….I mean who does that anymore?!?  They are always accommodating with our work/school/sports schedules and with two local offices to visit I have never had any issues getting my son in.  Dr. Nguyen LOVES what he does and it is evident every time we visit.  Can’t wait to see my sons new smile!

My daughter had 6 years of orthodontia treatments prior to seeing Dr. Nguyen. Her teeth were very off, and she didn’t feel confident smiling. Dr. Nguyen was able to correct her teeth. We didn’t think it was going to be possible! She is thrilled, and so are we.

Scott C. from Laguna Niguel, CA (Source: Yelp)


Dr. Nguyen has sponsored school visits, belongs to professional organizations, is board-certified beyond what is usually required to practice orthodontics, and always seems to be ahead of the curve on new technology to enhance his practice.  His staff are pleasant, with a comfortable mix of personal and professional.  Our child’s teeth are straight and staying that way (despite probably not wearing the retainers frequently enough).  Dr. Nguyen could have declared victory, gave us a hearty handshake and sent us on our way.  But I think his personal standards for care are much higher than that.  We still go for maintenance check-ups every 6 months to 1 year – all without additional charge – just to make sure that the treatment is complete.  It is service above and beyond what you expect from an orthodontist.

Adults are motivated by different reasons to pursue orthodontia and, in my case, it was a combination of aesthetics and functionality. Having a medical background myself, I made sure to research and interview my dentist’s referrals and chose to go with Dr. Nguyen because of his training, experience and attention to detail. Anyone can straighten teeth, but not everyone makes the effort to strive for perfection in an effort to get the best possible results. Dr. Nguyen’s staff went above and beyond in accommodating requests for any between-appointment adjustments and never made me feel like I was being unreasonable. I must admit that I’m surprised by how far orthodontia has evolved since I first had braces 40 years ago! In fact, it’s been a completely different (positive) experience. Dr. Nguyen has corrected years of shifting and even has helped resolve jaw pain, reinforcing my belief that it’s never too late to look good and feel great at a competitive price. With Dr. Nguyen it’s not a one and done…here I am over a year after getting my braces off and the complimentary check-ups really speak to how seriously Dr. Nguyen takes his work and commitment to patient care. I highly recommend gifting oneself with Dr. Nguyen’s orthodontia care!

Everyone at this office is so friendly! I love going to my checkups because they make me feel so welcome (Plus I feel safe going to their office since they have taken precautions with COVID). Dr. Nguyen takes the utmost care with his patients and I’m glad I chose his office for my orthodontic care. My teeth have shown a lot of improvement in a short amount of time and I know it’s because he’s so meticulous with his work.

Kelly M. from Mission Viejo, CA (Source: Yelp)


At 46 years old I made the decision to have braces put on for the first time in my life. Based on a referral from my dentist, I was very pleased with the choice of Dr. Nguyen. His approach to fixing my smile was one of a highly skilled engineer. I not only had three gaps to close, but a tooth that was so far pushed back in the front you could barely see it and a tooth on top that was turning sideways. Truly a hot mess. He sent a plan for me, we met every 4 weeks and 22 short months later I have a smile I never thought I could have. Dr. Nguyen is amazing. He is highly skilled, very professional and genuinely cares about you and your smile. He tops it off with having the best staff to support him. They are all knowledgeable and kind. Thank you for everything you did for me and my beautiful smile and for the welcoming family feel whenever I came in for my appointments. Sincerely, Kelly

Dr Nguyen is currently treating two of my children, so far we are very happy with him. I love the way he runs his office, he communicates well with his staff. The staff seems happy and they all get along so well. They understand the doctor and each other even before the sentences are done sometimes, it’s fascinating listening to them. His office is a well oiled machine, everyone knows exactly what they need to do and do it well. My daughter who is 12 was anxious to get her braces. After the consultation, Dr Nguyen recommended we wait until she reach her physical maturity level. He took time to explain to my daughter and I, showing us her spine x-rays and where it should be at until she’s ready for her braces. While treating my middle son Dr Nguyen had my daughter under observation and last week she finally had her braces. The day after her braces were put on his assistant Debbie called on his behalf in the evening to check on her. I thought I was really kind of Debbie, that goes to show how caring this office is. My oldest son had his braces done by another orthodontist who used to teach at an University, he was supposed to be one of the best in his field but in my opinion his level of expertise would not measure up to Dr Nguyen. My regret is that I didn’t find Dr Nguyen soon enough for my oldest son.

Best Ortho we have ever had. He and his staff are incredible. They make you feel so welcome in person and over the phone. We have seen better results in 3 months being at Dr Nguyen’s office than 2 years with my sons previous Ortho. Five stars ⭐️ ⭐️ ⭐️ ⭐️ ⭐️.

When it came time for my daughter to get braces I took her to the practice I had mine done 10 years earlier, as an adult. I was surprised to find that my orthodontist had retired, but I was told by his remaining staff, daughter-in-law included, that he researched extensively for just the right person to take care of the families in our community. His due diligence gave us the best orthodontist you could find. Dr Nguyen was phenomenal with my daughter and the results are perfect. My daughter got her braces late, 16yrs of age, so it made her case more challenging. Dr Nguyen was thorough, patient, knowledgeable, strived for perfection with his results, didn’t rush the process, and was extremely meticulous. These are all the things you want and should look for in an orthodontist. In addition my daughter loved him. He engages with the kids involving them and explaining the process to them, and I also loved that he would always have educated academic conversations with them. His office staff is amazing as well. They are friendly, accommodating, very helpful, and know their field. They all work very well together with Dr Nguyen. It’s a very well oiled machine. My son his starting his orthodontics with Dr Nguyen in two weeks. We look forward to another 18 months with Dr Nguyen and his staff and to the perfect results we know we will receive.

Absolutely love Dr Nguyen & his amazing staff. He is technical and very particular about his work while also kindhearted and humble. The entire office is timely, always calls to confirm appointments and never gives me a hard time when life happens and I need to move my appointment. Above all my teeth look incredible…and they fit ME. Dr Nguyen doesn’t have a one size fits all approach. He worked with my bite, facial features and natural look to design the best look for me. Highly recommended!

Melinda M. from Laguna Niguel, CA (Source: Yelp)


We are new to Dr. Nguyen and just starting the braces faze of our life with both my boys.  I took my sons here after seeing a few other orthodontists.  All seemed just fine, competitive pricing, but when my sons walked in to Dr. Nguyen’s office, they just loved it!  The staff was so friendly, they have a great incentive program to get your kids to brush and Dr. Nguyen was just fabulous.  He doesn’t mind the parents watching as he places the braces on your kids teeth.  His office is care free, friendly, and my final decision was their availability should we have a braces emergency.  Their schedule is excellent with morning and evening appointments so your kids do not have to miss school.

The best Orthodontist in town…hands down!! The entire staff exude warmth from the minute you entered the door. Dr Nguyen is compassionate and takes the time to examine and determine the best possible treatment plan without the cost of tooth extraction. My twin girls are excited about getting braces….and I think the “reward system” of ortho bucks is always a plus �

Kathy N. from Dana Point, CA (Source: Yelp)


I am copying Wm K’s review as he says it all perfectly. Dr. William Nguyen is a serious artist. He takes every case to perfection. His team is knowledgeable, hospitable, great chair-side manners, gentle, easy appointment scheduling, understanding when you have to cancel, easy financing and a just an all around painless experience. There are so many orthodontia choices in South Orange County but I know I made the right one with this office. Without hesitation, I highly recommend Dr. Nguyen and his team! I would like to add, Dr. Nguyen is an expert in his field and a master of moving teeth in their proper spots. My daughter had three impacted teeth (not her wisdom teeth) in both upper and lower. They were in a lateral position and backward position when we began the orthodontia work. It is a genetic condition that runs in my family. Both of my brothers had the same condition 30+ years ago and I witnessed first hand the difficulty and complexity of the masterwork involved as they both were patients of the orthodontist I worked for while I was in college. I do not work in the dental field, nor am I personal friend. I am sharing this only because I realize the challenge involved. Some orthodontists would not even take on such cases due to the uncertainty of the outcome and would opt for surgical extractions and implants. Dr. Nguyen took on the challenge and succeeded beautifully. I have included before and after x-rays to give you an idea of the transformation. Please keep in mind, this is a lengthy process and the patient needs to understand that, but well worth it in the long run. Highest recommendation! This link is simply a share for a coupon for free consultation:… Again, I do not work for Dr. Nguyen, nor am I getting paid for this review. I simply would like to share my experience and save you the headaches, time and money of trying to find the right orthodontist. He is your guy.

We have been going to Nguyen Family Orthodontics for approximately two years. During this time, they have consistently been friendly and professional. The office is a very welcoming environment and you are treated with genuine kindness and respect. Dr. Nguyen considers the best course of action for his patients and is meticulous about details to ensure amazing results. My daughter is now happy and confident with her smile. I highly recommend Nguyen Family Orthodontics for all your orthodontic needs!

I would like to thank Dr. Nguyen and everybody else there for the best customer service they have to offer! They treated my teeth as best as they could and my teeth today look as best as they’ve ever looked! I highly recommend you go in and get your teeth fixed because they dont false advertise, you will walk out of there with a better looking smile!

So wonderful to have not only a fabulous orthodontist but his amazing team and support staff. It’s a pleasurable experience from the moment we walk in through the door to the time we literally leave. I never thought a child having braces would be so easy and pain free! For the parent as well as the child! Thank you Dr. Nguyen, for being so fabulous and having such a great team!

Kelli H. from Rancho Santa Margarita, CA (Source: Yelp)


Dr. Nguyen is the best! My daughter’s dentist referred us, and even though we live in Rancho Santa Margarita and the office was a bit of a drive, it was so worth it. In fact, when it was my son’s turn for braces, it was a no brainer! The office staff is genuinely nice and cares about my entire family. It is easy to schedule appointments. The waiting room time isn’t long. And Dr. Nguyen’s work is impeccable. There’s no such thing as “good enough” in his vocabulary. It must be perfection. And both of my kids’ teeth are proof of that. We couldn’t be more pleased!

I’ve known Dr. Bill personally for a few years now and when it came time to choosing an orthodontist for both our kids, there was no choice. Dr. Bill is very approachable and has great beside manner. My son has been seeing him every six weeks for the past year for his braces, and he loves Dr. Bill. We have been able to see noticeable changes is his bite. We have the utmost confidence in Dr. Bill’s recommendations so when he suggested a tongue crib to stop our daughter from sucking her tongue, allowing her front teeth to grow in, we went with it. Three months into treatment and again, the changes are very noticeable. With Dr. Bill, you get caring, friendly and personalized service from someone who is very knowledgeable about what your child’s orthodontic needs are and he’s got a highly organized and professional office staff to boot. We cannot thank Dr. Bill and his staff enough and wouldn’t hesitate to recommend him.

Dr. Nguyen and staff has provided my son with top notch excellent care! They were always very caring and checking on him both for his orthodontist care and his medical. My son’s teeth look amazing. Dr. Nguyen and staff always made sure he was comfortable during each visit. Dr. Nguyen has now helped two of my children have amazing smiles and the youngest just got his braces on. I couldn’t have found a better Orthodontist!!

Janet Murr (Source: Google)


We could not be happier with Dr. Nguyen. He has been our orthodontist for both our kids and they have beautiful smiles. More importantly, they have teeth that are aligned and straight and look amazing. My son in particular started out with a severe overbite and Dr. Nguyen’s careful attention to detail has resulted in a perfect bite. What I like most about him is that he takes the time to explain things to me in a way I can understand them. I would be remiss if I didn’t mention his wonderful staff. I am one who always has to reschedule or check when my appointment is or is running late no matter how much I try and they always have a friendly smile for me and know our whole family. In addition, they handle everyone who comes in that same family! Thanks everyone at Dr. Nguyen’s office! Sincerely, Janet Murr

R. P. from Laguna Beach, CA (Source: Yelp)


My husband and I were very dismayed from a previous orthodontist on phase 1 of our son’s treatment, so it took us time to move forward even though we knew our son needed a second phase. Dr. Nguyen is​ a recommendation from our son’s dentist. We had lots of questions before, during, and after. In the end, our son’s teeth look great! Dr. Nguyen is skilled, precise, and honest in his work. I don’t think you could put yourself or a loved one in more capable hands.
