Combining experience with advanced education and personal care, we strive to bring you only the best orthodontic treatment options available including state-of-the-art braces and Invisalign clear aligners for those who don’t want to be seen wearing braces.

Dr. Flanagan is one of only 150 orthodontists in the World who has received special training from Invisalign for treating teens with Invisalign Teen, so you're in very capable hands while having treatment here at Flanagan Orthodontics!

Dr. Flanagan does amazing work. My sons teeth turned out amazing and we are about to start 2 more in his program. The lifetime retainers has been a... life saver. My son managed to lose 3 retainers in one week, all were replaced at no charge and they even worked with him to make a plan on how to not lose anymore. Pricing is comparable to the areas pricing. Friendly staff and a fun program for the kids.read more

The staff are incredible! Very welcoming and so informative! My kid already has braces from an out of state orthodontist and yet I learned so much... that I didn't know from just the consultation! They only do treatment that is necessary and at a cost that is beyond reasonable! 10/10 we all highly recommend!!!!read more

I felt so comfortable 100% of the time and my teeth look so much better than they did before! They were so good with attending to anything I needed and overall my experience was amazing!
