About Flanagan Orthodontics: Winnebago Location

A conservative approach that avoids pushing unnecessary treatment, paired with a lifetime retainer option families say saved money across several kids.

Reviews frequently note a conservative treatment philosophy under Dr. Dennis Flanagan, with several mentioning that unneeded procedures weren't pushed on their kids. A lifetime retainer option comes up repeatedly as a money-saver for families with multiple children in treatment over the years. Reviewers also point to gentle handling during bracket installation and simple, jargon-free explanations of both treatment plans and financing. Some also mention a doctor transition at the practice that went smoothly for existing patients.

We absolutely have loved Flannigan Orthodontics- both my kids went for early screenings every 6 months. The fact that we never felt rushed into multiple rounds of braces for no reason was a huge bonus. The staff are wonderful and most recently both my kids (11) have met Dr.Nudera and were very comfortable with him. Which is awesome because we were all a bit worried with the change over. He was so kind to them and explained everything to me as well. We highly recommend this office for orthodontic care!!

The level of professionalism and compassion here is outstanding. The staff were especially amazing with my child, who has autism. They were patient, respectful, and created a calm environment that made the visit go smoothly. We felt supported the entire time.

Everyone was ssssooo nice! I was expecting to go to an office where I’d be pressured into work my daughter may or may not need, then pushed into a credit card when I said I won’t be able to afford the full amount of expensive work, with uncouth doctors and standoffish staff. BUT to my surprise everyone was so friendly, conservative with the braces that will need to be done at a later time, and the candy counter was the cherry on top! Thank you everyone for such a great experience. They speak to you in easy to understand words, no scary medical terms I can’t understand, awesome prizes for the kids! Made me feel welcome and so much more comfortable with going to dentists. 👍🏼😄 can’t speak highly enough of Dr. Flanagan’s office.

What an amazing office! As we arrived for our very first visit, we saw a “welcome new patients” sign with my son’s name on it. He smiled so big. We open the door and immediately know this place is special. The warmth and friendliness of the staff was felt from the reception desk all the way through the exam/consult and as we left. My son, who is only 8, was a little nervous about going to the orthodontist, but after that initial visit, I have to say he is excited about going back. He felt comfortable with everyone. They explained things so he could easily understand and take better care of his teeth. I can’t say enough about the staff and doctor here…they are just the best!

My son is a new patient and we have had a wonderful experience so far. All the staff has been so kind, prepared us for what is to come with orthodontics and has answered questions patiently. It is also wonderful that they have little prizes and candy for their patients at the end of each visit. Can not recommend this place enough!
