Infection control is very important to us. To protect our patients and team, we strictly maintain sterilization and cross-contamination processes using standards recommended by the American Dental Association (ADA), the Occupational Safety and Health Administration (OSHA) and the Centers for Disease Control (CDC).

I even had to bring my 5-month-old and they took such good care of us!Posted on Google Janessa AllenTrustindex verifies that the original source of the review is Google. I have a severe phobia of the dentist due to mistreatment from a past dentist when I was younger. I have never been cared for so graciously and kindly by a dentist/hygienist like I was treated today. And my teeth look so much better and more white! I’m actually looking forward to my next cleaning. Thank you from the bottom of my heart!

The best dentist around. From the friendly and helpful reception staff, to the oral hygienist, and Dr Sewell himself, this is a great place to visit for personal care and attention. They do not try up-sell you on stuff you don't need and don't overcharge. They do a thorough job and carefully explain what is needed and at what cost. I am so happy that people referred me here.
