Sharing Smiles & Improving Lives



Our practice has a uniquely large team of doctors and staff, and this is with great intention. We wanted Cornerstone Dental Arts to be able to serve every single smile in Knoxville, and we want our patients to know that someone will always be here, ready to help them. While we may be large, we never confuse quantity for quality. Each member of our team is a highly dedicated dental professional with years of experience who is here to do just one thing: give all of our patients beautiful, healthy smiles they can be proud of.

Special care went into making our office feel like a home while maintaining an atmosphere of complete professionalism. Although we are sure our caring doctors and friendly team will make you feel welcome, we provide additional amenities to enhance your experience.

You can help yourself to a refreshment from our beverage bar, then relax in the treatment chair with a pillow and warm blanket.

What patients are saying

Randy Johnson

Worth the six hour drive!

I had to move to Virginia 2 years ago because of family. I still drive 6 hours back to Knoxville for all my dental needs at Cornerstone Dental Arts. Been a patient of Dr. Griffin since 2003.

Wayne Parker

It’s the way a professional dental office should make you feel: like family.

Whenever I leave Cornerstone Dental Arts after a visit, I always feel good about the experience—and about my smile.

DJ Miller

I couldn’t ask for a better dental office.

Everyone has been so nice and helpful! They are always happy to talk when I have questions or concerns. I came in for Invisalign and the doctor made sure to answer all my questions and went over all the pros and cons of my choice. Thank you, Cornerstone Dental Arts!

Cindy Stoerker

Whatever I say wouldn’t be enough to describe this fantastic dental office.

My husband raved about Dr. Griffin and I was fortunate enough to meet Dr. Williams and Morgan. Everyone always has a smile and soon you are treated as a friend. Would recommend Cornerstone Dental to anyone and everyone.

Katie Anderson

Highly, HIGHLY recommend this dental office!

AMAZING, KIND, and ATTENTIVE staff! Very thorough and honest!

Leigh Bagwell

Cornerstone makes me love going to the dentist!!!

At Cornerstone Dental Arts, I’m not just a patient, I’m a part of the family! From my very first visit, the entire staff has invested in my dental care and in me as a person! I trust them completely. I am so grateful that I found Cornerstone when I moved back to Knoxville. I know if I need anything at all, there is a team of folks that I can call on for assistance.

Erika Biddix

I’m so happy I found Cornerstone!

I came to Cornerstone on a recommendation, and now I recommend them to everyone! All of their staff, from the dentists to those that run the administrative side are friendly, caring, and efficient. We are never kept waiting and feel like we get top-notch care.

Lisa Beets

I have been a patient for 10+ years and have a great experience each time I visit.

Great dental office. Friendly staff and doctors that care for their patients. Even my two 4-year-olds look forward to going to the dentist. They love getting ‘Princess’ and ‘Super Hero’ polish on their teeth. Love this place.

Deborah Fouts

This place and these people are a perfect fit for me!

After having a really bad experience at another dentist I wasn’t sure I would find a place that was a good fit for me.
Cornerstone Dental Arts is such a special place. With a really great staff, I felt like I “come home” each time I enter their doors. I feel so at ease and well taken care of.

Friendly, caring, and professional staff across the board!

Danielle Cockrell

We absolutely love going to Cornerstone!!

All of the staff is amazing, super friendly and very caring for their patients!! Even my 9 year old gets excited to go to the dentist!

Madelyn Oster

The “Four Seasons” of Knoxville Dentistry!

I have been going to Cornerstone since I was a child and they always make my experience so welcoming and timely. I have never once dreaded my dentist appointment and I have Dr. Williams and his team to thank for that. Thank you for creating a space for us to come and have not only dental work done successfully but have meaningful conversations. I love to recommend Dr. Williams and the Cornerstone team to my friends and family.

Airren Parsons

10/10 recommend this place for all your dental needs.

The entire staff is amazing! Great communication and very friendly. From start to finish I had an incredible experience, which is saying a lot for a dreadful root canal. Dr.Williams does amazing work!

Ed Gray

Wish I had found them years ago!!

Highly rated professionals, who are very kind and down to earth in communicating with one. A large practice, with several dentists. You feel though you are their only client. They take your problem and quickly resolve it.

Tabatha Massengill

This place is fantastic!!!

Great atmosphere, friendly, and Dr. Stroud was phenomenal! For the first time in my life, going to the dentist wasn’t a horrible, painful experience. I have definitely found my new dentist. I would highly recommend them to anyone who needs a dentist.

Matt Kaye

I chose Cornerstone and my experience has been fantastic.

It’s been a long time since I needed a new dentist. I chose Cornerstone and my experience has been fantastic. Today I had 2 old fillings replaced, and it was fast easy, and painless. They used a laser system I’d never seen before, and I was done without shots or numbing…. there was no pain!! Great experience, I was out of the chair in 30 minutes with no lasting effect.

Jean E

Absolutely, the BEST staff and dental office by far.

Kim reminds us of my dear Aunt Mary Lou… kind and caring in every way. Dr. Griffin is skilled and so personable. MaryAnne, Gail, and Carol also have a great rapport with the customers. They make you feel like family. Thanks for all you do for us.

Jenna Vannoy

I’ve been a patient here for almost 20 years… I will never go anywhere else!

They’ve taken care of me after hours, on weekends, and even when they were on vacation! I’ve had multiple surgeries and procedures and STILL look forward to seeing them! Dr. Griffin is fantastic and so caring!!!! Dr. Williams and his staff are the best!!! I love Morgan and Carla and the rest of the team! If you are looking for kindness and compassion look no further!!!!!
