A cinephile since his earliest years, Isenberg now works extensively as a filmmaker—writing, shooting, and editing short documentaries for a variety of clients. During the day, he serves as chief videographer for the Jewish Alliance of Greater Rhode Island, where he develops monthly video content for Jewish Rhode Island.

Earlier, he produced regular video profiles on notable Arizonans for the Phoenix New Times.

Isenberg also takes on numerous personal projects, which have screened at film festivals all over the world and garnered more than a dozen awards (most recently, Best Documentary Director from the Block Island Film Festival).

His portfolio also includes short narrative and experimental films, including collaborations with the Rhode Island Historical Society and the Wilbury Theatre Group.
