Ruditis was born and raised in Philadelphia. He attended West Chester University where he majored in Theatre Arts with a directing emphasis. After graduation he moved to Los Angeles where he began working at Paramount Pictures where he worked as a tour guide and usher. Eventually, he took a position working in the studio's licensing department where he worked my way up to middle management before quitting to focus on writing.

Ruditis' first publication was in a Buffy the Vampire Slayer short story collection, which was being edited by a friend. Since then he has published tie-in novels and official guides to many hit television shows such as Buffy the Vampire Slayer, Charmed, Angel, Queer as Folk, Star Trek, Roswell, The West Wing, Alias, Prison Break Bones, The Brady Bunch, The Hardy Boys, The Girls Next Door and Sabrina, The Teenage Witch.

He has also published original fiction including the DRAMA! series and the controversial young adult book Rainbow Party.

In 2010 he began working with comic company Zenecscope Entertainment on a comic series based on Charmed as the series' main writer. The comic features an all new storyline set after the series' conclusion and has to date been very popular with the first issue selling out in it's first three weeks. For Issues 0-3 Ruditis co-authored the series with Zenescope veteran Raven Gregory but from Issue 4 onwards he penned the comics on his own.
