What Our Patients say


Angie W.

All of the staff were super friendly and wonderful! Jennifer Waters is by far the best dental assistant I have ever encountered. She was excellent and helpful in explaining what steps were being done in my visit and I felt in great care! I was very impressed by the clean, modern and hi-tech office!


Julie M.

Thank you for the wonderful, painless dental work! Your work was amazing – saving two teeth that other dentists told me needed to be pulled and replaced with implants. Your expertise also filled a tooth other dentists said needed a crown Your work added up to a large savings for me and is greatly appreciated! I have recommended you to anyone who is looking for a dentist or is unhappy with the one they have. My husband, who dreads going to the dentist, is looking forward to his first visit. Your whole office and staff is positive and welcoming.


John R.

As a medical professional, I envy the friendliness and welcoming attitude that your office staff convey. I know all too well that this doesn’t happen by accident. Kudos for your overall office atmosphere!


Kathryn P.

Shannon was probably the best Hygienist I have ever worked with. I can really tell that she loves her job. You guys do a great job with your marketing as well as educating your patients. Your excellent customer service helped me to feel relaxed and at ease during my visit. You have definitely won my loyalty to your business for as long as I am in Knoxville.
