Took my grandkids to this office today and was totally impressed with the service. Teressa, Zoe and Dr. Ashley were all kind, attentive and informative of their needs. It was a great experience.

My daughter’s first dental appointment and we both had a great experience! Zoe was SO kind and made the experience less scary for my daughter and Dr. Culver was very knowledgeable and gentle with her as well! The entire office staff was really nice and welcoming. Definitely recommend for your little ones :)

I gave this place of business a 5 star because they are pretty awesome! However what i experienced today was a bit confusing. I took my 7 yr old for tooth extraction (first time ever getting a tooth pulled) when they came out to get him I was instructed to stay in waiting area..I proceed to ask why and was told “we try to do things without the parent “ now if you’re teaching independence I get it but, explain that to the parent and give them that option still . Mind you there were 3 parents after me that went back with their children , My son went back without me and ended up soiling himself which has never happened (he’s 7). I was not pleased, he told me beforehand that he was scared. Will I still recommend this place? Absolutely! But I will be verbal next time about going back with my son. I do want to mention I spoke to the front desk about it and she offered for me to go back but my attitude wasn’t in the right place. I believe if I went back with him he would have never peed himself.
