Juston Roy Graber was born in Buffalo, New York to Lori (Brennan) and Roy A Graber, who worked as a construction worker/roofer. Juston's father always stressed the importance of education, however, Juston did not attend college until later in life.
As a child, Juston never found it difficult to make others laugh, even if it meant at his own expense. His outgoing personality craved the spotlight. His natural comedic and dramatic qualities are what attracted Juston to the entertainment industry. His close friends helped to spark Juston's interest and pursuit in acting as a career. They all agreed that his personable traits, along with his discipline, fellowship, genuineness, and even goofiness, might elicit even greater abilities as an actor and establish a solid foothold in a rough, but promising business.

In Fall of 2017, Juston was cast to play Colonel Triletzky in Michael Frayn's adaptation of Anton Chekov's untitled play, familiarly known as "Wild Honey" directed by Guillermo Cienfuegos and performed in USC's Bing Theatre.
