This place ROCKS!! Staff is all amazing!! The Doc makes you feel like family. Couldn't ask for a better Dentist. Thank you all so much Life time client
Cam Schieno
We had to switch dentists after our previous one was no longer in our network, and it turned out to be a blessing in disguise! The office was able to get us in right when we needed to be seen, and the entire staff was so friendly and welcoming. Dr. Kolten is extremely kind, gentle, and took the time to explain everything in great detail. We’re so glad we made the switch and highly recommend this office!
Heidi Chase
Best dentist I have used since I was a teenager. They treat you like family and still give you excellent care. They explain everything before they do it and even talked about the new machine that was used on me. From the office ladies on up to the dentist super knowledgeable and friendly. I recommend them to everyone.
Lori Kessel
Exceptional experience here with Dr. Kolten and his staff! I had a very sensitive tooth that needed a crown. Dr. Kolten treated the tooth with a desensitizer before he was able to do the same-day crown! I’ve never been to another dentist that used a desensitizer before. It was a game changer. And being able to get my permanent crown in the same visit was awesome!! They also brought me a big warm blanket while I waited for my custom crown. Definitely recommend Legacy Smiles to anyone and everyone!
Jordan Sharp
I love going to Legacy Smiles! I honestly can't wait until I get my teeth cleaned next! I have been going to there for over 14 years now and wouldn't go anywhere else. The staff is great and makes you feel like your part of the family! I highly recommend them for all your dental needs!

Everyone is very friendly and welcoming. I am a new client at this facility and they showed their appreciation and concern towards me. Answered the many questions I had and I was able to make an appointment the next day! I have not been to the dentist in a long time, I am glad I chose Legacy Smiles.
