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 got my Invisaline here and I had an amazing experience! It’s a very professional and welcoming environment and the staff are extremely nice, it... feels like I’m revisiting friends every time I have an appointment! 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! Would definitely recommend Flanagan Orthodontics :)read more

They were extremely welcoming and explained everything well. They are also about helping the child, not making a profit by making kids have... unnecessary procedures.read more

I love staff and Dr Flanagan. Always feel welcome and they are all very personable. I am 61 years old and did not think I would ever have my teeth... straightened out. Dr Flanagan provided the invisalign treatment. Very affective. Thank you for everything!read more
