Born in Vermont in 1969, Josh Peterson grew up in Brooklyn, the Washington, D.C. area, and overseas in Beirut, Lebanon. After graduating from Harvard in 1991, he moved to the San Francisco Bay area, where he worked with legendary maverick filmmaker Rob Nilsson for several years as an actor, assistant director, and editor. Since the early 1990s, Peterson has worked as a freelance editor for clients ranging from KQED to Lucasfilm to Apple and countless independent documentary producers making films for PBS, ABC, the Sci-Fi Channel, National Geographic Explorer, and others. He recently edited the award-winning Born This Way, The Welcome and Skin of Glass. He was nominated for a national Emmy for Outstanding Achievement in Editing in 2009 for his work on Soldiers of Conscience. He also edited The Rape of Europa, which was short-listed for a Best Documentary Academy Award.
In 2010, Peterson returned to narrative projects. Since then, he has written and directed several short films of his own, including the award-winning Forest Born and The Night of My Death, and his first feature film, Like Reply Share, which won the Best Drama Audience Award at Cinequest in 2020. His musical short, Thirsty,  premiered at Tribeca in 2021, and his latest film, The Unbroken Sky, is beginning its festival run. He lives in Berkeley, California.
