Fun Facts

The best advice Dr. Tharayil has ever received is “Push yourself because no one else is going to do it for you.”

As a child, he wanted to grow up to be just like his dad “because he’s my hero.”

Treatment of sickness is a part of medicine, but it’s not the whole of medicine. The world doesn’t need more smart doctors; it needs more warm and wise doctors.
