Zac Nicholson


Zac is a director, cinematographer and editor from New York City. He first garnered an interest in dramatic storytelling as a child, while singing with the Metropolitan Opera’s Children’s Chorus. During those five years, he was drawn less to the singers on stage as to the men and women behind the curtain who pulled the strings. It didn’t take long until Zac realized the almost limitless world of film was a better fit and he started making his first films on 16mm while still in high school. A graduate of New York University, he has worked as a freelance filmmaker in narrative, documentary and commercial production for the last thirteen years. Zac first collaborated with Janet Tobias on her documentary No Place On Earth in 2010 and is currently in production on two other projects with Ms. Tobias. Since 2010, Zac has also been a core member of the Ikana team, traveling far and wide to tell incredible stories about health care and the people whose lives have been changed as a result of medical innovation. While not filming, Zac can usually be found on an ice rink with a hockey stick in his hands or running in Prospect Park.
