Although my college degree is in nursing, I have been working in the dental field for almost 30 years and have been at Pleasant Dental since December, 2016. After staying home with my two children through their early years I decided I needed to find a career that enabled me to be home nights and weekends. The dental field was a natural fit.

I love dealing with people and making them feel at ease in a sometimes stressful environment. It is truly rewarding to see someone’s life transformed by the simple act of giving them a healthy and beautiful smile!
