About Your Dentist

"I enjoy building relationships with my patients. I enjoy learning about them and their dental needs and goals. Only then can I truly give them the dental care they want and need."

In addition to his formal education, Dr. Nguyen will continue to seek out advanced educational opportunities to better serve his patients.

Making a Difference With Every Smile...

"My goal 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 there is a link between oral health and diabetes, heart disease, and much more. It is my responsibility to help educate my patients about 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!"

Caryn Ayarzagoitia, DDS

"It is incredibly rewarding to make my patients comfortable prior to their procedure, relieve their pain and then see them smile back and be proud of their oral health. In addition to the dental treatments, I enjoy seeing my patients happy and satisfied with the education I provide them."
