A Smile Can Change Everything

The staff are very friendly, and they offer flexible schedules and always follow up each visit. Dr. Ouellette did a great job. I highly recommend him.

We had an excellent experience with this orthodontic office! The entire team is incredibly welcoming, friendly, and great with children, making every visit easy and stress-free. The office is always clean, organized, and runs on time. Dr. Ouellette takes the time to explain everything , answer questions, and he genuinely cares. Highly recommend this office.

Dr. Ouellette and his staff are amazing! They are all skilled professionals that made my teeth look beautiful 💕. I highly recommend!

This place is awesome! The doctor takes the time with each patient and helps them understand the whole process of braces. The staff are so helpful to making sure everyone who comes here is comfortable with the process of getting new or adjusting braces. St. Johns Orthodontics is a great place in our community and I recommend this place for anyone who needs it.

Soooo Glad to of found Dr. Ouellette! Can't wait to start orthodontic treatment soon! I have heard such great things about him and Heather from my oral surgeon and her staff! Edit: 2 years later..... finally almost time to get these braces off! Wonderful experience. Great doctor and even more wonderful staff 😉 Super accommodating because I require a lot of attention 😬 and have lots of questions. I reccomend them to everyone and will be mad if my friends or family go anywhere else 🙃 Look at my teeeth change . Perfect ♡ Now im got my daughter in there too. We drive almost an hour there and almost an hour nack home just to come here. Passing by at least 50 offices e

This office is wonderful. We’ve needed to come in to fix our wire they fit us in without a problem. Always friendly and helpful.

I first saw Dr. O in 2015 for adult orthodontic treatment, and he delivered exactly the results he promised. Due to a military relocation, I had to complete treatment elsewhere, where the quality of care—particularly the retainers—did not compare. After returning to Florida, I sought orthodontic care for both myself and my son. After multiple consultations throughout Nassau County, I found other offices to be significantly more expensive, with less reasonable treatment plans. Choosing Dr. Ouellette’s office was an easy decision. Their pricing was a fraction of others, they handled all insurance claims seamlessly, and the entire process was efficient and well-organized. The team is punctual, communicative, and thorough in explaining treatment options.I drive all the way from Fernandina beach just to get the best care! It’s well worth it! I am extremely pleased with both my experience and my son’s care, and I look forward to our final results.

This is the most consumer centric orthodontist! They anticipate our communication with thoughtful texts. They are super flexible with payments and appointments. And their team from phone to chair are kind and understanding. We were stuck in traffic for 30 minutes and they talked us thru next steps! It’s a cute, clean office and the team is always kind, fast and efficient. Our child loves wearing their t-shirt so she can ‘spin the wheel’ for great prizes. 😄❤️👍🏽 Thankful for how they make tough things so much easier!

Our family had a very good experience with St. John’s Orthodontics, from the staff to Dr. Ouellette. They are professional, friendly and are quick to respond. We had braces done for my daughter and I would recommend them.

I am very pleased with how fast my teeth have not only become perfectly straight but also with my overbite! Everyone is pleasant to be around.

Update: 31 MAR 2026 — Four years in working with St Johns Orthodontics, and we’re still feeling the love! ******* Son #2 got his braces today, starting Phase 2 of his treatment after already fixing his sever overbite. Both of my sons have been helped by this practice, and I hope to get my daughter into them yet this year as well. Hands down, we absolutely LOVE St Johns Orthodontics and Dr Ouellette and his team!

We are so happy we chose St. John’s Orthodontics. The entire staff is friendly and always helpful!
