Born and raised in the Philadelphia area, David was obsessed with movies and music. If he wasn’t watching movies he was practicing drums. After high school, David studied film at Temple University but also took a year off to study drumming at the Musician’s Institute in Hollywood.
Upon graduating from Temple University, David moved to Los Angeles permanently after being accepted into the Academy of Television Arts and Sciences summer internship program. The internship paved the way to his editing career.
As an editor working in premiere commercial post production houses, David has cut for Nike, Google, Ford, Chevy, T-Mobile, and Mazda, including Super Bowl spots for Hyundai and Butterfinger. His advertising work has been recognized by Ad Age, Shoot, Creativity, and AICE.
In 2011, Trachtenberg edited the viral sensation Portal: No Escape directed by Dan Trachtenberg and the Sundance Jury Prize-winning short Brick Novax's Diary directed by Matt Piedmont. His first feature was the Piedmont directed 2012 film Casa De Mi Padre, starring Will Ferrell.
David’s collaboration with director Alfonso Gomez-Rejon began with the 2015 Sundance Jury Prize and Audience Award winning film, Me & Earl & the Dying Girl. The film earned him an Eddie nomination and in 2016 he was inducted into the American Cinema Editors (ACE).
David’s latest work includes the pilot episode of the acclaimed Amazon series The Boys (2019).
His latest feature film, The Current War, was released in the U.S. on October 25, 2019.
David is known to cut the occasional Bar/Bat Mitzvah video, too.
