Connie Nash

Registered Dental Hygienist


Hi! I am Connie Nash. In 1983, I graduated from Clayton State College with an Associate degree in Dental Hygiene. I worked with Dr. Hamel during the late 90’s when our practice was focused on cosmetic dentistry. After I had my two children I focused on being a mom and reduced my working hours.  My son, Reid, is now 16 and my daughter, Taylor, is 22.  I returned to Dr. Hamel’s office in 2014 to be a part of an amazing dental team.  Our practice continues to change as we meet the needs of forever changing health challenges that face us all.  We now focus on biologic dentistry which excites me.  Being a breast cancer survivor myself, health has become of extreme importance to me.  I look forward to meeting new patients as well as faces I have missed through the years.  My love will always be dental hygiene and assisting each patient with their individual needs.
