There are so many orthodontic locations in Rockford. Finding Flanagan Orthodontics was like finding a golden needle in the haystack! I am forever happy that I kept looking and looking until we came at the door step at Flanagan Orthodontics. When my daughter and I stepped in we instantly knew there is something special and good about the place. No fret, no worries, and no pressure! They get it, they understand what parents are going through in this process, even kids. To this day we are forever thankful for Dr. Flanagan and his wonderful team of professionals. Everybody have a job to do and they are so proficient and knowledgeable at it. They are a well oiled office machine and run the business like a clock never missing a beat. They deliver what they promises up front every step of the way. My daughter is extremely happy that her daddy picked a good orthodontic care facility(her friends tipped me off when I asked where did they go for their braces and most got it at Flanagan!) ;-). If you are new and looking for an orthodontic shop around at several locations and then make Flanagan your last stop and I guarantee you it will be your last stop because you will instantly feel and see the different and know 'This is the place we've been looking for!'. Thank you everyone at the Rockford location. Your the BEST! I am usually picky and critical when a service is not delivered as promises and not afraid to make it know, but I am happy and smiling this is not the case with Dr. Flanagan. He delivers because he knows every aspects of this business. Experiences and his loyal team members/staffs got him where he is today. He's one of the kind and curved his own niche with what Flanagan Orthodontics is all about. Check them out, last!

Went in for an initial consultation with my 8 year old daughter. They are extremely personal and do everything they can to make the kids feel comfortable. The advancements that they have made in the Orthodontic field will make it a very comfortable experience for her.
