About Us
Our Message
Our philosophy is a simple one rooted in medicine’s first rule –first, do no harm. We believe in treating the patient then the disease. Simply put, your well-being and comfort is our priority. We especially feel this is an important virtue when treating our children at our office. Instilling fear of the dentist into a child is only likely to produce fear of dentistry as an adult. We believe respect and building trust with our patients is an important step in establishing a rapport that leads to a beautiful, healthy smile for a lifetime.
As in treating the disease, we employ ever-present modern technologies and materials and pride ourselves in maintaining a clean, modern facility. We believe the patient deserves the best in care and in quality when it comes to their dental health.
The Team
At Greenville Family Dentistry, our caring team takes the time to listen to your concerns and understand your symptoms. We believe that open communication plays an important role in accurate diagnosis and effective treatment.
We also take time to discuss your treatment options and payment details so you feel informed and confident in your care. An informed patient is key to achieving the best results.
