What Our Clients Say About Us

  • "I started going to Dr. Hoza's office after my mother and son said how much they enjoyed their dentist and staff at the Healthy Smile Center. They certainly were right!! I have been going for almost 5 years now and have never experienced anything painful or uncomfortable. Using some of the technology and Dr. Hoza's caring chair side manners and expertise, make every visit a pleasant one for the patient. Please read on to see the wonderful transformation Dr. Hoza did for my husband."

  • "After using another facility for a couple of years, because of insurance reasons, I decided to return to The Healthy Smile Center. I was greeted like a family member returning after a long time away. I immediately felt comfortable and welcome. Everyone is so kind and helpful. I am so glad to have made this decision. As for the insurance matter, the plan you offer is much better."
    BJ Leers
  • "At the recommendation of my chiropractor, I inquired about evaluation for TMJ from Dr. Debra Balough-Crombie. Prior to receiving treatment for TMJ, I suffered daily with tension headaches, neck and shoulder pain, and frequent migraines. Dr. Debra performed thorough evaluative x-rays, and measurements to determine the extent of my disorder and the appropriate course of treatment. Within weeks of receiving my orthotic appliances, my quality of life began to change. The headaches were becoming less frequent and I was working from a good night rest. It has been 2 years since I received initial treatment. I still wear my nighttime appliance to prevent teeth clenching and my daytime appliance as needed during stressful periods, but undoubtedly the TMJ treatment I received has improved my quality of life forever. The daily headaches are gone and I get a full night rest. Thank you to the professional and caring staff at The Healthy Smile Center!"

  • "GONE! Gone are my dead front teeth, my recessed lateral incisor, and my many fillings! This dramatic change came about because I inquired about whitening. I now have five crowns and one veneer. I am thrilled with my new smile and my much whiter teeth. Dr. Hoza and his team have been wonderful each step of the way. I never dreamed this change could ever happen. Each step was carefully explained and Dr. Hoza made sure I was at ease all the time. I am glad I had this opportunity. I am so pleased with the result!"
