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

All I can say is wow… When I scheduled my consultation, I was NOT expecting to get braces that same day. Never once did they “pressure me into a sale”. The staff’s knowledge and their advanced technology really impressed me. Never once did I feel rushed. After getting my braces on I was given a Sonicare toothbrush, I thought this was awesome considering how many thousands of dollars I was about to invest into braces. This is the BEST toothbrush I have ever used and I am thankful that they thought to include such a nice brush in my braces package. The night that I got my braces on, Dr. Soper himself gave me a call to check on how I was doing (how sweet is that). I feel very involved in my care, they sent a letter out to my normal Dentist and thought to CC me on the letter. I’m very grateful that I chose Advanced Orthodontics for my treatment!

Absolutely love Dr Soper. He is genuine kind and competent. Our son trusts him and has no anxiety about seeing him, and that we feel is due to his kind demeanor. His practice is extremely busy and that speaks volumes. Dr soper is honest and fair. He puts his patient needs first and is very respectful. We feel very lucky to have him as a provider and were referred by a staff member who used to work for him and all her children had their orthodontist work performed by Dr Soper. Thank you.

Dr. Soper and his team are amazing. We have been traveling from Auburn to Bellevue for now 3 kids in braces, and would not change a thing. Flexible scheduling, awesome front desk staff, caring and concerned technicians, and a fantastic chair-side manner.

Advanced Orthodontics has been the best dental experience both my wife and I have experienced. Matt and his team continue to take care of our needs after the invisiline treatment was completed. The customer service that has followed with repair and options is spot on. Thank you Advanced Orthodontics.

I had a wonderful experience with Advanced Orthodontics. I could tell that the Dr. Soper and his team truly found it important to provide quality dental care, and that’s what they did. Everyone was extremely kind and considerate, creating at atmosphere that I was very comfortable to be in. Additionally, the team was very knowledgeable about the treatment, which is shown in the results! Each appointment was quick and enjoyable, and the whole process went by very smoothly.

As someone who has suffered crippling dental-phobia my whole life the team at Advanced Orthodontics will always be credited as the ones who helped me get over this fear. I have been seeing them for over 2 years now while getting my adult braces and the experience has simply been amazing. The team led by Dr Soper are very friendly, knowledgeable and empathetic. They have supported me through the whole process and been very respectful of my desires and required outcome. I would recommend the team to anyone looking for Orthodontic work in the Seattle Metro area.

Lesalle M. from Bellevue, WA (Source: Yelp)


My experience with Dr. Soper and his staff was nothing but exceptional. Everyone was professional, friendly and accommodating. I had braces in for little over a year and the entire process was seamless and the results fantastic. I highly recommend this office for all your orthodontic needs.

We are so glad to have chosen Dr. Soper and his team at Advanced Orthodontics for the treatment of our son’s orthodontia needs! My son’s teeth look great! The team here always made him feel comfortable and answered all our questions! I was always able to get in if we had an “emergency”. And when I had a question about my youngest son’s teeth, they were able to do a consult right then and there. I wish we could see them for all our regular dental needs and will be sad when our youngest finally “graduates!”.

Dr. Soper is very knowledgeable and professional. He lets us know all the options and results of treatment, which makes it very easy to make a decision. Also he keeps up with all the latest technology in orthodontics, the name “advanced orthodontics” is so right about it. All the staffs are so nice and you will feel welcomed. Highly recommended!

Derek Y. from Seattle, WA (Source: Yelp)


This entire office embodies what it means to be people people. Outside of providing amazing service for my Invisalign treatment they have gone above and beyond while I experience personal tragedy in my family and proven they are real people and not just another Orthodontic practice. They step up when it matters most!

Tommy B. from Bellevue, WA (Source: Yelp)


Dr. Soper and Dr. Roloff are extremely professional orthodontists. They provided outstanding service to all their clients. The rest of their staff are excellent communicators with their patients. The equipment used by their office is cutting edge technology, which helped shorten the length of time I had to have my braces on! I really can’t say enough good things about the doctors and staff. I highly recommend Advanced Orthodontics!

Jenny L. from Seattle, WA (Source: Yelp)


Dr. Soper and his staff are super fun and professional! I came in for a consultation for braces and got them on the same day by Yana. Yana was super quick and professional and got my braces on within an hour! All the equipment and technology they use is very modern and high tech which I appreciate. You can tell Dr. Soper cares about the outcome of his patients teeth and how their smile will turn out. He took the time to explain how my teeth are now and where he would like them to be at the end of my treatment. I really trust Dr. Soper and his friendly staff including Ashley!! I am so happy I found a great ortho office that I love!

Pat M. from Tumwater, WA (Source: Yelp)


My girlfriend and I came on a consultation and it was better than I expected. Tuesday, the lovely treatment coordinator, was fabulous and got to know us on a deep and personal note. Took the time to listen to our needs and even helped us with our Financial Arrangement. I have heard about Dr. Soper and thought there was no way he could live up to the reputation that proceeded him; I couldn’t be more wrong. Dr. Soper was perfect and took the time to explain what we needed and inform us of something we never would have know without his state of the art x-ray and knowledge he has accumulated over his professional years. Overall the experience was amazing. Our next review will be how the braces have worked: will keep you posted on the progress. A+++++++ in service, friendly staff, clean environment, and professionalism. Could not be happier and we have only been in the office for 1 hour and halfway through our same day treatment!!!

Aparna P. from Redmond, WA (Source: Yelp)


Dr. Soper and his office are very professional. Dr. Soper is knowledgeable and takes time to answer any questions concerns. I received a call from the Dr in the evening after I got my braces to check how I was doing – I think that was very thoughtful. The staff is also good and patient. Overall I highly recommend this place for Ortho work.

Michelle B. from Bellevue, WA (Source: Yelp)


The team at Advanced Orthodontics has been incredible to work with. My son needed a lot of ortho work done including expanding his jaw and aligning his teeth. Dr. Soper is great about explaining what was needed and why and his staff has been superb in making some difficult ortho appointments and treatments manageable and even fun for my son (and me). The client service and dental care have been exceptional each and every time.

Dr. Soper is the best Otho in town and his assistants are all amazing. Yana you are awesome the whole team is perfect! We have seen Dr. Soper and his team for over 8 years now. Have always had a great experience. Thank you.

Gail Y. from Issaquah, WA (Source: Yelp)


I just finished my 9 months of treatment with Advanced Orthodontics and my experience was amazing. Everyone at work couldn’t believe how beautiful my smile is. Dr. Soper and Dr. Roloff and a fabulous team, so knowledgable, positive and excellent listeners. The staff and assistants are also superb. My appointments were on time and often I got in earlier than the assigned time. They predicted one year of treatment but I was done in just 9 Months. I would highly recommend them to anyone considering orthodontic treatment. Gail Y.

Advanced Orthodontics has been pretty good so far. Just started treatment so I’ll need to update this in a year. The consultation was easy to set up and benefits/costs were explained well. I did wait awhile before meeting the ortho but I assume it was just a busy time. Just started my treatment as of this week, but I have no complaints. The team at Advanced Orthodontics are professional and easy to work with. Overall, I would recommend them to a friend.

Lauren T. from Seattle, WA (Source: Yelp)


Advanced orthodontics went above and beyond to accommodate my needs. First, I wrote down the wrong appointment time and the day of they were able to give me the appointment I needed. Then, I was running a half hour late to my appointment and they still happily fit me in. The staff was wonderful and friendly, and I am so gracious that they made the whole experience into an extremely pleasant one! My son can’t wait to go back for his next appointment!

While my initial engagements and treatment at this office was excellent, midway through, a disappointment happened. Wires on my treatment broke late on a Friday night — imagine broken wire on your front teeth! After leaving a voice mail on Friday night and then another voicemail at opening of the office on Monday morning (7:30 am), I had to call a second time on Monday to get an appointment for Tuesday (none sooner). I was 10 mins late to this appointment (yes – late, my bad). I took time away from work to get there, arrived and was returned back with the explanation that I could not be seen since there was not enough time for it. The reception staff was pretty rigid and not sympathetic by any means. They suggested there was time to see me next day – none of which worked due to my work schedule. So here we go, wires on the loose, from Friday to Thursday (almost a week later, next possible appointment was that), and treatment that is regressing. Love this office and the practice. Yet, scheduling and responsiveness can do better.

Mat K. from Auburn, WA (Source: Yelp)


We have seen Dr. Soper and his team at Advanced Orthodontics for years with our kids, from our first evaluation 6 years ago with our oldest, to our first treatment with our youngest. We make the trip from Auburn to Bellevue thru eastside traffic with the kids for treatment because Dr. Soper and his team are worth the trip. They are kind, caring and compassionate with the kids. Braces can be tough on a kids self esteem, and my kids are handling it phenominally because the staff is so supportive. The team explains everything that is going on during treatment, from expected discomforts to long term gains for all to understand. We could go to a local orthodontist, but we choose to make the drive because it is well worth it. I could not recommend them any higher. Wish there was a 6th star.

I have been going to Advanced Orthodontics for over ten years now and every experience at their office has been wonderful. The staff is great and all genuinely want to engage with you. Dr. Soper is very funny and knowledgeable. He makes orthodontics as painless as possible. Everyone is professional and friendly. I have and will continue to recommend Advanced O.

My experience with Dr. Soper has been nothing but excellent from the very beginning. I am in my braces for the last 6 months. The staff is always on time. Quality care provided with kindness. I am always informed about what will occur with a smile. I am 57 and this is the second time in my adult life I needed orthodontics. First time was 37 years ago. I went in with experience of what to expect. This has been a superior experience so far. Deborah Flynn.

The staff at Advanced Orthodontics are “awesomely awesome” according to my son! We have been going there for 2 years and they have been wonderful. We are seen promptly and are provided with excellent explanations of what is being done and what we need to do at home. Thank you for making our orthodontic experience fantastic!

Today was just another example of why I am so glad I chose Advanced Orthodontics. I left the office with a great big smile on my face, having felt like I matter. In a world where everyone is so rushed, I cannot express how wonderful it is to have the whole team make me feel so welcome and valued. I cannot recommend Advanced Orthodontics enough for the quality of care, skill and professionalism, and that everyone is just so kind and friendly.

Zhanar Baizhanova (Source: Google)


My experience at Advanced Orthodontics has been great. Dr. Soper is professional and truly cares about his patients. I had a concern and he listened to me and resolved it. The assistant staff is also very good at their job. I particularly like Shawna. She is been great and gentle during my regular visits. The front desk is very friendly and helpful too. I highly recommend Dr. Soper for anyone considering braces.

Thelma M. from Washington (Source: Yelp)


We started our journey after a referal from dr mandich and with no regrets. The staff have always been pleasant & courteous, and the dentist knowledgeable and professional!! Everyone worked together on scheduling and making sure that my sons crossbite was fixed in the time quoted. Thank you Advanced Orthodontics.

L. B. from Meridian, MS (Source: Yelp)


Dr Soper and his staff are excellent. Really enjoyed the service for all my children. Erin is exceptionally knowledgeable and helpful with the insurance claims. My oldest is out of his braces and his teeth look perfect. The middle two are still in braces and the care and treatment received at advanced orthodontics is superior. The youngest will be going there eventually, too.

Hamza A. from Bellevue, WA (Source: Yelp)


I had a fantastic experience with Dr. Soper over 24 months as he worked on my teeth. I never had braces as a child and required quite a bit of work (in coordination with my dentist and an oral surgeon) and Dr. Soper and his staff were certainly up to it. We initially started with lingual braces (at my preference) but after we found that these were moving too slowly Dr. Soper switched me to regular braces for no additional charge. Even though the treatment went 6 months beyond the initial estimate I was never asked to pay an additional fee. I would highly recommend him. The assistants are also, for the most part, top quality though they do change from time to time.

Dr. Soper is wonderful ! He has an amazing staff as well. I was at a previous orthodontist and switched to Dr. Soper. Based on a friends recommendation and, I have only continued to be impressed and thrilled with the work he has done for my 3 kids. I have previous dental experience myself. Prior to Children, I worked at a dental office for 6 years. Dr. Soper and his staff are top notch. You know this when you have worked in the field. I love how personable Dr. Soper is. He takes time to actually talk to the parents.

Alex G. from Seattle, WA (Source: Yelp)


Just finished two years of treatment with Advanced Orthodontics, and their team is excellent! Both Dr. Soper and Dr. Roloff are wonderful, as are all of their assistants and staff. They always greeted me with a smile, started my appointments on time, and took good care of me while I was there. They explained my treatment options and set expectations clearly up front, and I’d highly recommend going in for a consultation if you’re thinking about braces but have questions or just aren’t sure. The office is clearly geared towards kids, but I felt very comfortable as an adult patient. My treatment required jaw surgery, and they recommended and worked closely with Dr. Audia, who is brilliant (and right across the street). I don’t think orthodontia will ever really be fun, but the Advanced O team definitely made it the best it could be. And now I can smile again!

Mark M. from Bellevue, WA (Source: Yelp)


I went to Advanced Orthodontics (Dr. Brienne Roloff-Chaing and Dr. Barton L. Soper) for adult braces based on the recommendation of my dentist. Both Doctors worked seamlessly with my dentist and periodontist to provide all-around care and treatment for me and my teeth. In just over a year, I have a perfect smile and healthier gums. The Doctors and staff were always happy to see me and took excellent care of me and my smile. They uses the latest equipment and technology to speed up the entire process. I highly recommend Advanced Orthodontics to anyone seeking orthodontic treatment!

Lily O'Donnell (Source: Facebook)


Fantastic doctors, staff, facility, and overall environment! Dr. Soper and his associates are very knowledgeable and their quality of patient care is excellent. From the moment I walked into the waiting room, I felt at ease and not pressured. The office is fully equipped with the most up to date systems making appointments very smooth and efficient. I really feel valued as a patient and know that I am under the care of great doctors.Roopa Satagopan.

I was super impressed during our consultation with Dr. Soper. He connected with my daughter immediately, putting her at ease and was very patient in answering all of our questions. He was very knowledgeable and gave excellent guidance on a special case that we were working through in my daughter’s treatment. Best of all, he’s also incredibly personable and a pleasure to be around.

Kathy W. from Sammamish, WA (Source: Yelp)


We are extremely happy with all aspects of this office. It is easy to schedule and the techs are always on time. All techs are super pleasant and knowledgeable and great with the kids. Dr Soper is so easy going and interacts with the kids and parents in a very warm manner. We are pleased with the product they offer. They are always available to answer questions. You cannot ask for a better. House in orthodontics. The price was what we expected as well.


Because everyone deserves an incredible smile and the confidence it brings... Dr. Soper loves working with children and adults, creating beautiful smiles that give each individual a lifetime of confidence. He truly loves the joy in peoples’ eyes when they first see their finished smile and the confidence they show when they walk out the door to meet their friends and colleagues. His professional peers have recognized his level of excellence by nominating him numerous times to Seattle Magazine and Seattle Metropolitan Magazine as an outstanding orthodontist. Dr. Soper shares his knowledge with his students in both the undergraduate and graduate programs for which he is a professor at the University of Washington School of Dentistry
