About Thornell Dentistry

Our Practice

Making Our Community Smile For Over 2 Decades


Thornell Dentistry has been providing excellent dental care to the Herriman community since 2003. We moved to our current location in 2018 to have a better office layout for productivity and patient comfort.


As soon as you enter our practice, you will notice the Thornell Dentistry difference. Our friendly front desk staff will greet you with a smile and ensure you are seen on time for your appointment.


Dr. Thornell takes his time to examine all elements of the mouth to

ensure he makes the correct diagnoses and individualized treatment

plans to help each patient achieve optimal oral health.

After Hours


When he is not practicing dentistry, Dr. Thornell spends as much time as he can with his wife and four children. Together, they enjoy water skiing, camping, and playing with their Golden Retriever.


“To me, life’s all about family. That’s the way we live our lives and run our office. We even set up our appointments and work schedule so that you and I can get right home to our families after work- it’s what’s most important.”


Even when Dr. Thornell is not in the office, he is still often providing dental care. Through several missionary programs and the
Give Kids a Smile Program, Dr. Thornell donates free dental services to children in need of care but whose families can’t afford to pay for it. He also spends time supporting the local Boy Scouts.


In the future, Dr. Thornell would like to continue traveling with missionary programs and donating his services to bless the lives of many more families to come.

A Love of Dentistry


Dr. Rodney Thornell has always had a passion for working with people and science. Dentistry was the perfect choice for Dr. Thornell to incorporate his passions into a fulfilling career. 


“Initially I wanted to be a family therapist, but once I started observing with my dentist I fell in love with it!”


Dr. Thornell earned his Doctor of Medicine in Dentistry degree from the University of Louisville, a top 10 school for dentistry with a focus on family-friendly care.


“I hold the school in very high regard and when needed I’ll refer my patients to other Louisville-trained doctors because I know they are skilled and professionals in the dental field.”

Never Stop Learning, Never Stop Improving


Dr. Thornell understands that dentistry is an ever-evolving field and puts extra effort to ensure he is current on the latest advancements in dentistry. Although all medical professionals are required to continue their education beyond their degrees, Dr. Thornell spends 15x the national average on continuing his education.


“In order to be the best, you have to learn from the best. There is always some scientific advancement, new materials, and new techniques. Through my education, I find a better way of doing something that is more effective and lasts longer. My work keeps getting better, and that’s better for you.”


Advancements in technology and equipment can make dental procedures more comfortable, efficient, and reliable. Dr. Thornell invests in the most advanced equipment to give you the best care possible.

Dr. Thornell is proud to be involved with several professional dental organizations.
