As a physician, I’m passionate about preventative medicine and interventional cardiology. I have the privilege of making positive differences in patients' well-being.
Growing up in multicultural Malaysia, I was fortunate to live with people from diverse backgrounds, and subsequently, a wide array of cuisines. In my spare time, I enjoy camping as well as hiking with my senior labrador and my great dane puppy.
