This is the best dentist in town and they have always worked with me, and I'm terrified of going to the dentist. These guys are very fast in the dental work they do and super gentle

I have been a patient at Southtown Dental for several years. After 50 years of not looking forward to going to the dentist, I can say that I actually enjoy going now. The hygienist, Deanna, is outstanding. Not only does she do a terrific job but she is gentle and very personable. The office staff is professional and on point. They are also very welcoming and friendly. It really comes down to the dentist care which has always been very good. Today my teeth are clean and sparkly- I look forward to going back in 6 months!
