"Why did I become a pediatrician? I’m a big kid myself. Where else, as an adult, can you play with toys, watch cartoons, play video games, AND call it research? I have a room full of Star Wars paraphernalia, a room that idolizes my New York Yankees and a room that worships superheroes. I get to play in them EVERYDAY! Seriously though, my eighth grade yearbook says, “Ambition: Pediatrician”. It’s all I’ve ever wanted to do and I’ve never looked back."
