Why Choose Us

Practice exterior

“My experience with Tori was the best!!! She was super gentle with my teeth and even offered me some numbing gel when they were sensitive. I have never had someone so concerned with my comfort while cleaning my teeth. She’s the only one I trust with my teeth now!”

- Brook F.

“Windham dental group is the most professional and courteous dental office I have ever had the experience of being a patient of. Dr. Dennis Flanagan and his entire staff are incredible! Thank you for making my dental work pain free and for giving me the confidence to smile in public once again

- Andrew W.
