I've worked as a documentary photographer since 2012, with projects in Haiti, Guatemala, Uganda, and more, and publications including New York Magazine, the Los Angeles Times, and the U.S. National Park Service.

Since 2017, I've brought that rigorous field experience to teaching, primarily to beginners working through the same struggles you're probably facing right now. These courses are built around a proven method to simplify the way you learn photography.
