If you’re looking for an orthodontist in Briarcliff Manor or anywhere in Westchester County, you’ll likely find a range of providers offering braces, clear aligners, and other treatments. But not all orthodontists are created equal. Choosing a board-certified orthodontist ensures you receive care from someone who has achieved the highest level of clinical excellence and ethical standards in the field.
What Does Board Certification Mean?
Board certification is a voluntary process overseen by the American Board of Orthodontics (ABO). It requires orthodontists to undergo additional training, pass rigorous written and clinical exams, and demonstrate continued commitment to education and excellence. Only about one in three orthodontists in the U.S. are board-certified.
At Orthodontic Harmony, Dr. Tracy Li Cheung is proud to be board-certified—offering her patients a level of care that goes far beyond the minimum standard.
Meet Dr. Tracy Li Cheung
Dr. Cheung brings years of specialized experience and advanced training to patients in Briarcliff Manor and beyond. As the only board-certified orthodontist in the immediate area, she’s known for combining technical precision with empathy and thoughtful communication.
She also collaborates with other dental specialists for interdisciplinary care, helping patients who may need surgical planning, periodontal support, or restorative coordination.
Why Board Certification Matters for You
When you choose a board-certified orthodontist, you can expect:
Comprehensive diagnosis and treatment planning
Evidence-based techniques and technologies
Customized treatment options for your unique smile
Transparency in communication and outcomes
Higher standards of safety, ethics, and continuing education
This extra level of training can be especially important for patients with complex bite problems, previous orthodontic relapse, or unique medical considerations.
Better Outcomes, Better Experience
At Orthodontic Harmony, your care is never rushed or one-size-fits-all. Whether you’re considering clear aligners, digital braces, or early orthodontic care for your child, Dr. Cheung provides multiple treatment options tailored to your goals, lifestyle, and comfort.
We also offer transparent, flexible financial options and collaborate with in-network insurance providers whenever possible—because we believe everyone deserves access to board-level care.

Frequently Asked Questions
Board-certified orthodontists complete extra exams and clinical reviews to validate their skill, precision, and dedication to excellence.
No. Any licensed orthodontist can practice, but board certification is a voluntary distinction held by fewer than 40% of orthodontists.
While any provider can offer treatment, board-certified orthodontists are trained to handle complex cases and use proven methods for optimal outcomes.
You can search the ABO database or ask directly. Dr. Cheung’s board certification is proudly listed and updated regularly.
Not necessarily. At Orthodontic Harmony, we offer flexible financing and work with many insurance providers to keep care accessible.

5 stars honestly isn’t enough. I’ve been a patient here for almost 2 years and needed pretty extensive treatment for sleep apnea, including surgery and an expander. None of it was easy, but the care I received throughout the entire process was incredible.
Dr. Tracy and Ayxa are not only exceptional at what they do, but they’re genuinely kind people who truly care about their patients. They always took the time to answer my questions, made me feel comfortable, and never made me feel rushed. You can tell they actually want the best outcome for every person who walks through their doors.
If you’re looking for an orthodontic practice that combines expertise with genuine compassion, I can’t recommend Orthodontic Harmony enough. I’m incredibly grateful I found them.

Dr. Tracy and Aiksa are truly exceptional. Not only are they highly skilled and knowledgeable in their field, but they are also genuinely kind and caring people. Every time I visit, I feel welcomed from the moment I walk in, and I always leave with a smile and feeling better than when I arrived.
What sets them apart is how much they truly care about their patients. Throughout my treatment, there were a few unexpected challenges caused by mistakes from a previous dentist. While those setbacks were frustrating and extended the process, Dr. Tracy and her team handled everything with professionalism, compassion, and dedication. They corrected the issues and continuously supported and encouraged me during a stressful time.
Orthodontic Harmony is, without a doubt, the best dental practice I have ever been to. I am incredibly grateful for the care, kindness, and outstanding service they provide.

I went to see Dr. Tracy as an adult for treatment of crowding of my lower front teeth that was causing me some discomfort. She came up with an excellent treatment plan and executed it seamlessly within about an 8 month period from braces to retainer. I’m very, very pleased with the result both aesthetically and in terms of comfort. For personal attention, care, and excellence look no further than Orthodontic Harmony. Thank you Dr. Tracy and Ayxa you guys are the best!

Dr. Tracy and her staff are absolutely wonderful! We’ve had such a great experience with my son’s orthodontic care, Dr. Tracy is very responsible and professional with appointments, always organized and punctual. She explains everything clearly and takes the time to make sure we fully understand the process and treatment plan. She is also incredibly attentive, patient, and caring, which makes every visit comfortable and stress-free. Her staff is just as kind, welcoming, and helpful. We truly appreciate the exceptional care they provide and highly recommend Dr. Tracy and her team!

I was disappointed to learn that I paid ~$6500 for treatment only for this office to not have a finalized scan of my teeth on file. I was given active clear aligners at my final appointment in addition to several inactive trays and told that if I needed more trays I’d need to get my teeth rescanned and it would cost around $1200-1400. I ended up asking my dentist to scan my teeth as his office can mail you new trays at a moment’s notice if anything happens. This was especially disappointing because Dr. Cheung knew that I only lived here while my husband attended school, I’d never be able to get to her office to get rescanned if something happened to my trays.
Additionally, I was told the office could remove and replace my brackets/buttons for the clear aligners prior to my wedding as a complimentary service. In the end, Dr. Cheung felt I was far enough along in my progress that we didn’t need to put those particular brackets/buttons back after the wedding. I was fine with this because I trusted her opinion, but this resulted in a tooth on my upper left side sitting higher than the rest of my teeth. I was told this would get better, but it did not.
When I was initially invited to do a Google review by Dr. Cheung, I would’ve given 5 stars, but it was what happened at the finish line that really ruined the experience for me. My smile turned out beautifully, I just would have expected my tooth to sit flush like the rest of my teeth and for my final form to be on file without an additional cost.

This practice was recommended to me by a fellow parent for their caring approach to orthodontistry. And they exceeded our expectations! Dr. Tracy has the most wonderful bedside manner, which matters a lot when it's a child's first medical happening. She took an educational approach to teaching him and us about his expanders, with beautiful results 9 months later. The office has all of the things you want: clear communication, excellent management of payment and insurance matters, clean and convenient office and on time appointments!!! It really felt like having a family care for us! I highly recommend! We drove 30 min each way for the appointments and it was worth every minute for the supportive collaboration and great work.

Bar none. First off, their office is immaculate and extra clean. Dr.Cheung and her team are in a league of their own. This is my first time doing any type of orthodontic treatment (I needed alot of work). She is very thorough, precise and took her time to come up with my personal treatment plan, which she customizes for each patient and walks you through the whole process. It is a commitment on behalf of the patient as well which she helped me understand and iwas able to get on board and work with her. Im nearing the end of my treatment and it’s bittersweet because they’re really a pleasure to deal with. Bonus: Although I was ready to pay out of pocket for my treatment, she was able to work with my insurance! Thank you again Orthodontic Harmony team you!

Dr. Cheung and everyone at Orthodontic Harmony have helped me through my orthodontic journey in an unexplainable way. They made sure I was always informed, comfortable, and satisfied every step of the way. They helped me coordinate with my surgeon and my dentist to make sure there were no loose ends. I genuinely believe my orthodontic journey wouldn’t have been nearly as success without Dr. Cheung on my team.

My daughter and I had an excellent experience with Dr. Tracy at Orthodontic Harmony. She was recommended by our pediatric dentist and we very much trust his opinion. She was very clear about each step of the process and took the time to make sure we understood next stops as well. I would 100% recommend her to anyone seeking an orthodontist in the area.

We’re fortunate to have found Dr. Tracy Cheung and her team at Orthodontic Harmony. We, parents of a teenager, were complete novices in visiting Orthodontists’ offices to learn about the entire process of getting braces for our daughter. Dr. Cheung, her assistant, Ayxa, and staff immediately welcomed us and eased our apprehension. Among the myriad of great attributes of Dr, Cheung, such as her friendliness, professionalism, and patience, what we’re most pleased with is her integrity. We followed her clear guidance and saw the reinforced result. We firmly recommend Dr. Cheung, Ayxa, and everyone at Orthodontic Harmony to anyone who seeks the finest orthodontic experience.

My experience has been excellent. I came into the consultation not sure what to expect and with frankly low expectations of results due the extreme crowding. Fast forward and I have a great straight smile and the entire staff worked together as my team to get best results. The practice is pristine and so clean and they have the state of the art equipment for imaging to get best fit possible. I Highly recommend!!

I can’t say enough great things about Dr. Tracy Cheung, Ayxa and the team at Orthodontic Harmony. This was my last option for a third opinion of the process I needed to take for my smile. After a sleepless night and extensive research at 2 in the morning, I found Dr. Tracy at Orthodontic Harmony.
Not only is she a true expert but she as well as Ayxa are also incredibly kind and patient. Scheduling was very easy and once I came in for my appt, The protocols they follow to ensure cleanliness and safety is impressing!
Dr. Tracy explained each step of my treatment and what to expect, so I felt comfortable, confident and overall safe and completely at ease with the treatment option I was given.
The communication between the staff and patients has shown me that we are highly considered, thought about and cared for. The follow ups and the willingness to accommodate you if you have any questions or concerns is such an important factor because as patients we never just want to feel like just a patient but like family that matters. And Here, I completely feel that.
I’m so happy I’m at the hands of a skilled and excellent Doctor along with her team. I’m looking forward to continued progress (which I already see in just 6 months)
I truly appreciate the level of detail and dedication put into their work. If you’re looking for an orthodontist who combines expertise with kindness and excellent patient care, Orthodontic Harmony is the place for you. Where you walk in as a patient and leave as family.

Very nice orthopedic office. The staff is amazing and they do such a great job. They are great with getting back to you right away when you need to contact them. Also the doctor genuinely cares about how you feel about things and making the right decision for you and your family at the moment (both what’s going on physically with your teeth and financially in your wallet).

We highly recommend this practice to anyone who needs an orthodontist. Dr. Tracy has been working with my son for about 2 years as he prepped for, got braces, and went through the various steps. My son is amazing, but he is a teenage boy and also tends to chew on everything! Dr. Tracy was so supportive, encouraging, and positive with him, which made the entire process so pleasant. He struggles to remember certain routines, but she never made him feel badly and always worked with us to figure out the best way to help him do what he needed to do.
We had to move about 1.5 hours away in the middle of this process, and we chose to continue commuting back and forth to Dr. Tracy's office rather than finding someone new. It has been worth it because everyone at the office is incredibly friendly, supportive, and encouraging!
In addition, the change in his teeth and smile is significant and we are really happy with the results.
I would also add that this office is so on top of scheduling. We have never had to wait to be seen and are always in and out in a timely way - while never feeling rushed. I truly could not imagine a better experience!

Orthodontic Harmony has been treating my two children for the last 10 months. Doctor Cheung listened to my concerns about my child’s jaw alignment and tailored a plan of treatment that was specific to him and me! She did not jump into a treatment plan. Rather, she listened to our concerns as a family and made a plan that was best for us all! I have nothing but good things to say about both her and her staff.

We're so grateful for the care and attention that was provided. Highly recommend!

Wow! Where can I begin? I’ll start by sharing that I had a cross bite, flared teeth caused by a previous orthodontic treatment done elsewhere and of course my teeth were misaligned. Upon my first consultation Dr, Tracy knew exactly what I needed to start. My top teeth were crowded and I needed a palette expander to create more room in my top teeth. After that I had braces to correct my misaligned teeth. Both Dr. Tracy and Ayxa were very patient with me, interested in my concerns and thorough with every step that was performed. Their level of knowledge and professionalism exceeded my expectations. My braces came off today and I cannot express enough my gratitude towards this great team whom literally has helped me regain my confidence. My smile looks amazing :) and I don’t have to feel insecure about my teeth ever again! Thank you Dr. Tracy and Ayxa for all of your hard work and dedication because it is clearly evident and I will be forever grateful!
