My primary area of focus is in assisting patients through the denture process. From taking impressions to making adjustments, it’s a journey we take together, and I find immense satisfaction in helping patients regain their confidence and achieve a beautiful, functional smile. Dr. Hargett’s commitment to ethical care ensures that all options are explored, and our entire team works collaboratively, whether it’s assisting with procedures, ensuring a clean and welcoming environment, or simply taking the time to connect with patients and their families.
With the collective experience of our team, which spans over 40 years, our patients always come first.
