About Our Practice

Welcome to Lost Sierra Dental

Located in the heart of Quincy’s historic Old Town since 1990, our practice was founded by Dr. Herndon as a place for patients to get comprehensive dental care, including saving teeth from gum disease and replacing unsavable teeth with dental implants. Our focus is on you—our patient—and meeting your needs with the utmost precision, care and comfort. Our doctors will help you to achieve optimal oral health, which plays a vital role in your overall systemic health, and a confident, comfortable smile.
