Fun Facts

The best advice Dr. Koshy has ever received is “The goal isn’t to live a happy life; the goal is to live a meaningful life” and “It is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is able to adapt and adjust to the changing environment in which it finds itself.”

The most exotic places he has visited are Kerala in India, the Amalfi Coast in Italy, and Palawan in the Philippines.

Not everyone knows this about Dr. Koshy, but he was voted “best personality” in his high school graduating class.

Video games are his guilty pleasure.

As a child, Dr. Koshy wanted to be a businessman because he enjoyed building human connection and leveraging that to create value.
