My daughter had braces and we absolutely loved this place!! They are so caring & quick with getting back to you. We loved them so much that I now as... a woman in my 40s has braces for the first time in my life. I wouldn't dream of going anywhere else for orthodontist care.read more

I took my daughter into Flanagan orthodontics for a braces consultation today after not being 100% comfortable with the first place we tried. We... immediately felt comfortable and welcomed. Lauri is seriously one of the friendliest people I’ve ever met and I instantly knew this is where we’d be proceeding with her braces treatment. Dr. Flanagan was also very kind and took the time to patiently explain the whole process. So far, I’m very happy and so is my daughter!read more
