    Since I was young I had a dream to work in a profession that deals mainly with people, to help, comfort and relieve pain. Because I enjoy drawing, carving and working with my hands, I was seeking a 'hands-on' profession.  Hence Dentistry became my profession of choice as it combines both art and science. I always knew that you can dramatically change a person's life by changing his or her smile.

    Make people pain free, happy and satisfied with their smile, it is both challenging and rewarding
