Garret was born and raised in Southern California. As a teenager, he played lead roles in youth theater productions at the Laguna Moulton Playhouse in Laguna Beach. He also spent an awful lot of time recording his own radio shows and, with the help of his brother and sister, shooting stop-action films with their dad's video camera.

He got his B.A. in Film Studies at the University of California at Santa Barbara where his experimental film, 1-24, won the Bruce Corwin Award for Best Short and Best Cinematography.

In Los Angeles, he edited movie trailers and feature films, including the award-winning indie feature Olympia (Slamdance, Sundance Channel). He has worked in New York City as a commercial editor since 1997. During that time he managed to fit in a two-year stint at The Atlantic Theatre Company's Acting Conservatory.

His latest editing project is Justine Jacob and Alex Da Silva's feature documentary Paper or Plastic?, likely to premiere at a film festival in Spring of 2008.

As a director, his short comedies, The List and For Food, and short documentaries, 4-Cylinder 400 and Shoot the Freak, have played many festivals including the Hamptons, Hawaii, Nantucket, Woodstock, Coney Island, Williamstown, Crossroads, and Newport Beach. In early 2005 he was chosen by The Independent magazine as one of their Top Short Filmmakers.

He loves teaching and has been the Program Director for the Nantucket Film Festival's Teen Filmmaking Program and has mentored with Brooklyn's Reel Works Film Lab.

He lives in Brooklyn, NY.
