Dawn, Office Manager 

Welcome to our practice!

I entered in to the dental field as a dental assistant which has allowed me to understand the true concerns and the anxiety some patients face. I enjoy helping patients so much that I decided to expand and learn more about dentistry. Over the past 30 years I have had the opportunity to build personal relationships, working through treatment concerns and creating financial plans. It is very gratifying helping patients achieve and maintain their oral health. This has inspired me to grow in all those skills as much as I can. At Manhasset Miracle Smile, we have top notch patients and we provide the highest level of dentistry. This all just adds to a life that is fulfilled with family, friends, and enjoying the outdoors with my son.
