Meet Our Team

Welcome To Our Practice


Our goal is to partner with you to achieve your optimum dental health. Recognizing that comfort, appearance, and long-range economy are of prime importance, the treatment that is recommended for you is based on what Dr. Hollinsworth, Dr. Brent and Dr. K would recommend for their own families considering your wants and needs.

Our caring and upbeat staff want to make your time with us as pleasant as possible. You will always be treated as a guest when visiting us, and we offer amenities such as blankets and pillows to make you comfortable.You can bring in your own iPod or phone to play your music,too! If you are highly anxious, we offer nitrous oxide or "laughing gas" with a stuffed animal to hold if you like.

We will always strive to inform you about your dental health and current needs so that you are comfortable with your treatment . If at any time you have questions or suggestions, please do not hesitate to talk to any of us. We always welcome the opportunity to more fully meet your needs and to deserve the trust of those who refer new patients to us, for that is the nicest compliment we could ever receive.

Establishing a rewarding and lasting relationship with you is vitally important to us. We pledge excellence in all we do, and we look forward to helping you make the most of your smile now and for all the years to come.
