Making a Difference With Every Smile...

"Mygoal is to make a difference in every patient's smile. I enjoy having the opportunity each day to make a positive impact on my patients' oral and overall health. We know so much more each day about the link between the mouth and the body. We now know their is a link between oral health and diabetes, heart disease, and much more. It is my responsibility to help educate my patients on that connection.

Not only am I a dental care provider, I am also an advocate for my patients. I am grateful to have such a caring and dedicated team by my side to help me in this mission. At Dekalb Dental Group we will do whatever it takes to put our patients first!"
