Great place. Staff are all friendly and do their best to make you feel comfortable and relaxed. Dr. Definnes did a filling, a root canal, and a crown for me, and I am very happy with his work.

I have been a patient of Dr. Definnes for several years. I even have family members going here that did not like going to the dentist due to bad experiences with them. Dr. Definnes and his staff are professional. Dr. Definnes is gentle and genuinely care about your teeth and overall health of your mouth. My appointments have been true to the time I have been given. When I had to get root canal work done a couple years ago , it was no where near the nightmare stories I had heard from other people. The dental hygienists at this office are also great. I highly recommend this office.

Dr. Defining and his wonderful,staff are always very kind and do wonderful work on my teeth. I haven't had any cavities for five years now. I love the way Jamie cleans my teeth and love Dr. DiFinnis's hand shakes, knowledge, and kindness and smile. Thank you for making my visits happy and successful and helping me keep my teeth squeaky clean! See you in 2018!
