Dr. Scott Siemen
Associate General Dentist
My interest in dentistry began with my grandfather who was a dentist, so I was always interested in the profession. From there, I chose dentistry to help people improve their health. My general approach and philosophy in practice is to learn as much about each patients’ concerns, fears, wants and desires in order to create trusting and compassionate relationships. I enjoy learning each person’s dental story and then creating an individualized plan for long lasting health and beauty. Additionally, I love helping anxious patients overcome their dental fears, being part of a team that cares for the overall wellbeing of each patient and interacting with people to directly impact their health and self-confidence.
Dental health is an essential component of overall health. My strong points are my experience in diagnosis and planning. I perform restorative procedures including fillings, crowns, bridges, implant restorations and full and partial dentures. In addition, I have advanced training in cosmetic dentistry like bonding and porcelain veneers. I also perform extractions and root canals.
