I would highly recommend and we only did a consultation. The staff made my son and I feel very welcomed and comfortable. I had a very clear... explanation of everything and all my questions were answered. We were referred to some other orthodontist but I’m deciding to stay with Dr.Flanagan. So my son is now officially apart of Dr. Flanagan’s kids club.read more

Great experience, my teeth were very crooked prior to coming here. I needed to have corrective jaw surgery to fix my bite prior to finishing my... orthodontic treatment. Dr. Flanagan communicated frequently with the oral surgeons, monitoring my bite and teeth positions while my teeth were moved into preferred positions prior to surgery. Once my teeth were in their correct location I had the surgery and resumed the rest of the orthodontic treatment, my teeth have never been more straight! I love my smile and more importantly my bite is aligned and makes chewing food that much easier!read more

I love Flanagan! I've been seeing them for 8 years now for braces, headgears and finally a retainer and the office is so friendly and welcoming. I... looked forward to my monthly braces visits because everyone there was always very conversational and remembered me. My teeth are straight as can be now and I highly recommend seeing them!read more
