The Practice

A foundation of taking care of people.

Dysart Dental is a comprehensive family dental practice owned and operated by husband and wife team, Dr. Sam Thomas, DDS and Dr. Tracy Thomas, DDS. We are located in fast-growing Litchfield Park, Arizona.

At Dysart Dental, we aspire to stand above the rest by exuding excellence in all that we do. We have created the practice on the foundation of taking care of people. While fixing teeth is a very important aspect of dentistry, we accomplish so much more. We take on the challenge of caring for people's health with an emphasis on their oral health. More and more ailments of the body are being linked to oral health, and many diseases of the body first manifest themselves in our patients' mouths. When people achieve healthy mouths, their lives are genuinely improved. They are more confident, they smile more, they gain a new outlook and achieve things they may not have tried before, and most people simply feel better overall once their mouths are healthy.

"We do more than fix teeth. We change lives."

Dr. Sam & Dr. Tracy Thomas

Our office has a warm family atmosphere in which we provide care for every aspect of your oral health. As sole proprietors of our family business, we make sure that our hard work and dedication to health and beauty get passed on to every patient. Our training from the University of the Pacific School of Dentistry, one of the top-ranked dental schools in the country, allows us to provide state-of-the-art care from the day you walk through our door.

In addition to our technical skill, we feel that our personal character and strong relationship help distinguish our office in the Litchfield Park community. Sam's witty, fun-loving nature and ability to engage many different types of people is a benefit to our patient management, while Tracy's strong business sense and caring spirit help make Dysart Dental one of the most enjoyable and successful practices in the West Valley.

What We Believe

Three things we are not willing to compromise on.

Family first.

We treat every patient the way we treat each other. That means patience, real conversation, and an answer to every question. There are no chair quotas here. We will sit with you until you understand your treatment, your options, and your costs.

Excellence as standard.

Top-tier training from the Arthur A. Dugoni School of Dentistry. State-of-the-art Galileos 3D imaging on-site. Eleven specialty services under one roof. We invest in the best because that is what our patients deserve.

Lives, not teeth.

Healthy mouths change lives. We see it every day. The patient who finally feels confident in a photograph. The parent whose kid actually looks forward to the cleaning. The retiree who can chew a steak again. That is the work.
