Outside of work, he enjoys gardening with his wife, running with his dog, and playing squash as often as he can.
Fun fact: “I was 33 years old before I was able to vote for the very first time. I stood in line for more than 6 hours with people like me without a single complaint – we were just so excited and overjoyed to be able to vote for Nelson Mandela to be president!”
