Justin was born in the state of Illinois, specifically in a location that is not specified, but it can be inferred that it is a city or town within the state. He later grew up in the Los Angeles suburb of San Dimas, California, which is located in the San Gabriel Valley region of Los Angeles County.
Justin received a Bachelor of Arts degree in Dramatic Art from the University of California, Santa Barbara, which is a public research university located on the central coast of California. He then went on to earn a Master of Fine Arts degree in Writing from The School of the Art Institute of Chicago, which is a private art school located in the Loop community area of Chicago.
For many years, Justin worked in the theatre and independent film scenes in Chicago, which is a city known for its vibrant arts and cultural scene. He co-wrote the screenplay for Nate & Margaret, a film that was later sold to Breaking Glass Pictures and played at film festivals. The film received positive reviews from critics, including Roger Ebert, who praised its smart and observant portrayal of two particular characters and its pitch-perfect casting.
Justin's second co-written feature screenplay, Miles, was released in theaters and digitally in 2017 and starred Molly Shannon, Paul Reiser, Missi Pyle, and Tim Boardman. The film won the audience award for Best Feature at the 2016 Outfest, a film festival that showcases LGBTQ+ films and filmmakers. After the success of Miles, Justin moved to Los Angeles, where he currently resides.
