Best dentist I’ve ever been to.
Everyone is super friendly! Everyone is sooooo friendly and make you feel like you’re their family💜 100/10 recommended ! Thank you so much

I am glad I was recommended this office.
Cardinal Dental has been my one stop shop for anything to deal with my teeth. Everyone there is charming and professional and it is credit to their continued work towards excellence.

Most places say they will go above and beyond. No one is going to beat this one.
I took my daughter here for an Invisalign appointment today. I was so impressed with the staff and this doctor that I will be moving my entire family to utilize the full dental services that are offered here.
Too many things to mention- taking the extra time, the entire staff incredibly knowledgeable, everyone is friendly and truly cares and values your time and who you are as a person. They make you feel good and you actually want to go back….. to the dentist!! I would rate more stars if I could. Thank you Dr. Blalock for taking exceptional care of my daughter today. We will be back soon.


Dr. Blalock and her entire staff are PHENOMENAL.
They create such a fun, relaxed, and welcoming environment. They work hard to make sure your kiddo (or the adults as well!) feel comfortable and calm, making adjustments as needed. We live 45 minutes away from the office but I find it 100% worth the drive for such outstanding care!

Wherever you are on your journey, we can help :)
