Why Did You Choose Dentistry?
In my life, I’ve always been inspired by my mother’s example as a medical nurse. Witnessing her care for her patients with such passion always made me feel proud of her, and motivated me to do the same.

Therefore, when it was time for me to choose a career, I didn’t hesitate to choose dentistry.

What Is the Best Part of Your Job?
For me, dentistry is like a type of meditation that makes my life better in many ways.

What Do You Do Outside of the Office?
When I’m not working, I enjoy traveling, photography, and hiking with my wife and my little one.
