The Big Apple's CoRe Podcast: Conversation with John Sadlon

“Any of us can walk down the street in New York and we can see the world for what it is, but as an architect or designer we must be optimistic. We are futurists, thinking about improving the human condition. The headlines that you’re going to read about in two years are the exact designs that are on our desk right now; they are the projects that we are building with our clients right now. There is an incredible energy and also a significant responsibility that comes with that.”
