Best orthodontist experience, i love all these ladies. They’re so sweet and made my many years having braces comfortable 🧡
I can’t say enough wonderful things about Dr. Moynihan at Troy City Smiles. She is truly one of a kind. She's not only an incredibly skilled orthodontist, but an even better person. You can tell she genuinely cares about every patient and takes everything to heart, always keeping their best interests front and center. What really sets her apart is how authentic she is. She’s warm, thoughtful, and has an amazing sense of humor! I’ve belly laughed every single time I’ve talked with her. She has a way of making you feel completely comfortable & confident in her presence, which speaks volumes about how she shows up for those around her. She brings so much heart into what she does, and it shows in every interaction. I have no doubt she’ll continue to do incredible things and have a lasting impact on everyone she meets. If you have the opportunity to be treated by Dr. Moynihan, rest assured that you’re in the best hands possible.
Kayla is absolutely wonderful every time my son and I visit the orthodontist. She has such a kind, friendly, and professional demeanor that immediately makes you feel comfortable. What really stands out is how personable she is—she doesn’t just focus on the work she needs to do, she truly cares about the patients she interacts with. Kayla always takes the time to be welcoming and thoughtful, and it makes every visit a much better experience. We always appreciate seeing her! The entire office is always so welcoming as well. Dr. Katherine and her whole staff are fantastic—friendly, professional, and clearly dedicated to making patients feel comfortable and well cared for. It’s truly a great team. 😊
Dr. Katherine is the best orthodontist out there. She’s amazing, kind and always made me feel very comfortable being there. As a patient who used to hide my smile, her being my orthodontist helped me show it again! I would highly recommend coming here!
The staff are amazing. Always make my daughter feel comfortable. And Dr. Katherine Moynihan is absolutely amazing and so kind. Definitely recommend!
I had a very good experience with Troy City Smile. They take excellent care of their patients and answer all their questions. I'm very pleased with the results. Thank you very much for your excellent work!😁
Phenomenal office, my daughter got braces, her teeth were severely crooked.. now, they are perfect. The doctor and staff are all awesome, friendly and caring. Minimal wait time, I would highly recommend them!!
Dr. Moynihan and her staff are very pleasant, knowledgeable, and prompt. She had my daughter right on target as far as the amount of time she would have her braces on to correct her jaw. The way her teeth were aligned was affecting her breathing while she slept. She took every step possible to help me to have the insurance cover our treatment. I highly recommend this office.
Dr. Moynihan is a wonderful orthodontist! My first impressions were that she is very thorough and caring. I was impressed that she factors airway and systemic health into her treatment, instead of just making the teeth straight and not caring about the rest. Also, from personal experience and in speaking with others whose children are seen here, it's so great that they are willing to work with such a variety of kids' ages and insurances -- they treat everyone equally regardless, which cannot be said for other offices that my family and I have encountered. Very happy to have her locally and highly recommend!!
I recently finished my Invisalign treatment with Dr. Katherine Moynihan, and I couldn’t be happier with how everything went. As an adult starting orthodontic treatment, I was a bit nervous, but Dr. Katherine made the whole experience comfortable and straightforward. She explained each step in a way that was easy to understand, so I always felt informed and knew what to expect. Dr. Moynihan has such a positive and approachable attitude—it’s clear she genuinely cares about her patients. She was patient with my questions and took the time to make sure I was comfortable at every stage. Her professionalism and warmth made the entire process smooth and stress-free. I highly recommend her to anyone thinking about Invisalign or other orthodontic treatments!
Dr. Moynihan is a great doctor that took very good care of me, especially with my Invisalign treatment. Everyone that works here is very professional and I would definitely recommend this place to anyone!
Absolutely wonderful place! Dr. Moynihan is a gem. She is very informative and kind. I never had braces as a kid so I don’t know anything about this process and they’ve made it so easy for my kids and myself throughout this step in their lives. Highly recommend!!
Dr Moynihan is the absolute best! What she has done for my daughter's smile is amazing!
Amazing team! My daughter is glad to be back always a great experience. Its always very welcoming. She always comes out with a smile. ☺ ❤️ 🪥😁💞
I wish i could give 10 stars! Dr. Moynihan and her staff are extremely kind and professional! I’m 35 years old with braces so this wasn’t easy for me. What i can say with confidence is i wouldn’t want anyone else treating me! My daughter is also a patient here so that should speak to my level of trust in her! HIGHLY RECOMMEND!!
Wish I could Give her more starts!!! Excellent service & very professional!
Prompt and welcoming. My kiddo is happy to go back to someone we know and trust.
All the staff were very pleasant!
The office staff were very nice and my daughter’s appointment was quick.
Attention to detail is evident at Troy City Smiles, in both the practice and the level of care received. We feel our son is in good hands with his braces and are confident the end result will be a beautiful smile 🙂
New building, but same nice girls. Nice to see everyone again from their previous location but just be patient with them while they get acclimated to their new building
