My daughter was scared about having to get braces & work with male providers! She absolutely loves the O’Neil brothers, they made this experience for her so easy & fun!

We have always been very happy with Orthodontic associates. They have been great to work with and have done fantastic work for my son. We see Dr. O’Neil at their office.

Amazing practice. Kind, professional, courteous staff. Dr. Mayers has always gone above and beyond for my family and we've trusted him to treat all three of our children. Beautiful smiles and happy, healthy mouths for life. They work with our insurance, and the monthly payment options make treatment affordable as well.
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear about your positive experience with Dr. Mayers and our team. Your family's smiles are our top priority, and we appreciate your trust in us!
Megan N.
Great friendly staff and a wonderful environment. My son was very comfortable with getting his braces on. Highly recommend!
Response from the owner:Thank you for your kind words, Megan! We're thrilled to hear that your son felt comfortable during his visit. We appreciate your recommendation and look forward to seeing you both again!
Nickey G.
Orthodontic Associates is such a professional yet personal practice! Everyone is always so nice and helpful. They always are willing to answer any questions that I may have pertaining to my 13 year old son and his newly applied braces. Both Dr. O'Neil's are great doctors! I always recommend this Orthodontic practice to anyone that may ask.
Response from the owner:Thank you for your wonderful feedback, Nickey! We're delighted to hear that you had a positive experience with our team and that we could assist you with your son's braces. Your recommendation means the world to us! We look forward to continuing to provide excellent care for you and your family.
Jennifer H.
Incredible doctors and staff. Very caring. They did my braces over 20 years ago. Now the same doctor does my daughters. I would highly recommend.
Response from the owner:Thank you for your wonderful review, Jennifer! We're thrilled to hear that you and your daughter had such positive experiences with our team. Your recommendation means a lot to us! We look forward to continuing to provide exceptional care for your family.
Michelle F.
My son just got upper braces put on. I have nothing but amazing things to say about the wonderful person who put them on him! She was always checking in with him to make sure everything was okay. I would definitely give her her credit for an amazing job, but I forgot her name. Thank you Orthodontic Associates for a great first impression on my son, with braces. I was worried about how he would handle them, but it turns out I was worried for nothing.
Response from the owner:Thank you for your wonderful feedback, Michelle! We're thrilled to hear that your son's first experience with braces was a positive one. Our team always strives to ensure comfort and support for our patients. We truly appreciate your kind words and look forward to continuing to provide great care!
Shelley K.
We have had a great experience thus far. From our consultation to issues with pain, they have made us feel seen, and taken great care of us.
Response from the owner:Thank you for your wonderful feedback, Shelley! We're delighted to hear about your positive experience with us. Our team is dedicated to providing excellent care, and we're glad you felt supported throughout your visits. We look forward to continuing to serve you!
Jess H.
Everyone here is really friendly. The work they do shows for itself! I am on my second round of treatment with this company and they offer numerous ways you can pay for services that are accommodative to financial situations :)
Response from the owner:Thank you for your kind words! Your vote of confidence in our practice is why we do what we do!
Kara K.
My kids go to Dr. Janowski. He is great, and so is the staff! Everyone is very professional and kind.
Response from the owner:Thank you so much for the positive feedback. We are honored to serve each and every one of our patients!
Toshia M.
Dr. O'neal and his team are the best! We always have positive things to say but Kate really stood out during our last appointment. She was so sweet, caring, and informative. Dr. O'neal truly found his calling and we are blessed to call him my son's Orthodontist!
