” I post people’s stories as they tell them to me. I am not a journalist, I don’t verify, just listen. […]  Its very easy to simply run with your crowd, to not explore the amazing diversity and perspectives that are offered. Its also very easy to ignore others. By not looking, by not talking to them, we can often fall into constructing our own narrative that affirms our limited world view. What I am hoping to do, by allowing my subjects to share their dreams and burdens with the viewer and by photographing them with respect, is to show that everyone, regardless of their station in life, is as valid as anyone else.”
