Providing you with personable, efficient care
to maintain your beautiful smile.

It’s a pleasure to meet you.

Drs. Cass and Stephanie Cook married in 2009 after graduating from the University of Florida College of Dentistry together in 2008. They actually grew up in the same county, but never met until the day they started dental school. Dr. Stephanie always wanted to live here and they moved to the area in 2009 as soon as Dr. Cass finished his residency. They started Cook Family Dentistry in December of 2011, where Dr. Cass has been the primary dentist. They have since had three kids- Benton, June, and Kathryn, so Dr. Stephanie has stayed busy being Mom and an online health and fitness coach.

Our team at Cook Family Dentistry has a combined dental experience of over 40 years. Providing our patients with the most outstanding dental experience is of the utmost importance to us. We enjoy providing quality care as each patient has his or her own personal needs and concerns.

We want to serve our patients with compassion, excellence, and value. We take pleasure in making a difference in the smiles and oral health of our patients.

Our staff is highly qualified in meeting our patients’ dental health expectations. Our most sincere wish is that when you visit Cook Family Dentistry, you feel right at home.
