What People Are Saying

I have always had positive experiences here. I love that at least 2 or all 3 of my kids can be taken care of at once so there's no waiting on the other to be done. They are quick and polite and very family-friendly.

This practice in Lexington, was amazing. The dentist took her time and explained the treatment. I am new to SC. They took my son because of an emergency toothache. The staff was the best. The front desk secretary had the nicest smile and was patient. I will be bringing all the kids here.

Today was the first appointment that my sons and i experienced. We enjoyed the care and services rendered. Hope to have this same experience again. Looking forward towards our next appointments. Thanks

Love love this place!! They make the kids feel so great. My daughter just had her tooth pulled and she was scared. With Melissa and the Dr they kept her calm and relaxed and pulled her tooth without my daughter knowing!!

Everyone working here was so great to my daughter allison and I this morning. It was her first dentist visit and she was very nervous at first because didn't know what to expect but they were very patient and kind to her and she did excellent for them. They have a great atmosphere and an awesome little goodie bag for the first visit.
