A queer sci-fi / fantasy / horror writer in television, film and new media, Mario began his career co-creating, writing and directing the Mark Cuban produced web series THE VAULT, which garnered millions of views and awards recognition.

He went on to co-write and co-directed the psychological thriller feature CIRCLE which was acquired by Netflix. The film went on to become a cult hit, frequently included on "Best of Indie Sci-Fi and Horror" lists to this day (Buzzfeed, Bloody Disgusting).

Next, he co-created the streaming anthology series DARK/WEB which was acquired by Amazon. He served as showrunner, producer, and series writer, as well as wrote and directed one of the anthology episodes. The show earned 7 Daytime Emmy nominations including Best Digital Drama Series and Best Directing Team.

Mario also co-wrote the social horror film MADRES for Blumhouse. That film debuted on Amazon as part of the WELCOME TO THE BLUMHOUSE series and earned him an NAACP Image Award nomination for Outstanding Writing in a Television Movie or Special.

On the filmmaking side, Mario recently completed work on the micro-short ghost story RED LIGHT GREEN LIGHT and is currently in pre-production on a horror short film shooting later this summer.
