My husband and I both decided to do Invisalign together at Dr. Flanagan’s office and it was a really great experience. The process itself was relatively painless. Neither of us experienced a lot of soreness throughout the process. We were always able to make appointments that fit into our schedule and we had less office visits than with traditional braces. We both work full time and we have two small children, so this was important to us. The staff was very welcoming and friendly. They were quick to respond to questions we had and accommodate our needs. We enjoyed working with them. We are also very happy with the results of our smiles!

First, I have to say that from the moment my son and I walked in until the time we left, the staff was super friendly and informative. The office is inviting and very well kept. We met with Dr. Flanagan and left feeling very well informed.

I was impressed with the approach he wants to take regarding my sons orthodontic treatment and how he is focused on addressing crowding and my son’s bite.

I will definitely recommend Dr. Flanagan to my family and friends!!
