Personal Attention / Professional Excellence

"I have a sincere concern for my patients and want to partner with you as a facilitator to provide you with the high-quality dentistry you deserve. I have a servant's heart and truly enjoy making a positive change in your dental health. When I hear my patients make comments like 'Why was I so worried?' or 'That was the most painless appointment I've ever had,' I know I am doing things right.

My team and I love caring for our patients and helping improve their lives. We offer complete, state-of-the-art dental care, with a commitment to honoring and caring for the needs and desires of the people we serve. Our vision is to provide the highest quality of dental care and to transform the quality of life of our patients and their loved ones in profound ways.

The Dental Prayer:

Lord, be with me daily as I practice Dentistry.

May I treat with gentle hands all who put their trust in me.

May my calm assurance help to erase their fears.

To relax the tense adults and dry the child's tears.

May I treat each patient with competence and skill.

Whether a difficult procedure or a tooth that I must fill.

And reward me with my patient's lovely, healthy smile!


My Mission

To help and serve as many people in need as possible. My favorite part of dentistry is the patient interaction. I want to be very involved in my community, not just as a dentist, but as a friend to my patients.
