The Piedmont Dental By Design team · Grand AvenueFor 30 years, Piedmont Dental By Design has remained a locally owned, family-oriented practice — devoted to restoring and enhancing the natural beauty of your smile using conservative, state-of-the-art procedures that result in beautiful, long-lasting smiles.
Today the practice is led by its co-owners, Dr. Jill Martenson and Dr. David Ma, who share the same values that have guided the practice for three decades — trust, comfort, and personalized care.
What does Piedmont Dental stand for?
From sterilization to continuing education, six values shape every decision in the practice. They're what we measure ourselves against — not what we say to win patients, but what we follow to keep them.
We maintain a standard of excellence in personalized dental care, allowing us to deliver the quality services our patients deserve. Through comprehensive treatment planning and the use of restorative and cosmetic dentistry, we help you achieve optimal dental health. In an emergency we prioritize seeing and caring for you promptly.
Preventive care and education are key to optimal dental health. Our focus is on comprehensive dental health care rather than just disease care — thorough exams, oral cancer screenings, X-rays, cleanings, sealants, and fluoride treatments to prevent issues before they begin.
We build trust by treating each patient as a unique individual. Dental visits can be anxiety-inducing, so our team is committed to a relaxing and positive experience with personalized care from the moment you walk in.
Dr. Martenson and Dr. Ma stay current with advances in cosmetic dental science. Our office uses state-of-the-art technology including digital radiography — reducing radiation exposure by 80–90% versus film, with instant detailed imaging that catches hidden issues earlier.
Our highly trained team is dedicated to maintaining your dental health through continuous education. We stay current with the latest techniques, products, and equipment by attending industry events and as active members of the AACD, ADA, and CDA.
We prioritize infection control by adhering to strict sterilization and cross-contamination protocols based on guidelines from the ADA, OSHA, and CDC — protecting both our patients and staff at every visit.
At Piedmont Dental By Design, we take great pride in offering the very best in personal care. Our warm, family-oriented team values each patient relationship and prioritizes your comfort, making sure you receive the highest level of care tailored to your needs.
Choosing the right cosmetic dentist to restore or renew your smile is crucial to achieving a beautiful, radiant result. From routine cleanings to complete smile transformations, our team is dedicated to your dental excellence and comfort.
