Jon Parrish was born in Hammond, Indiana and attended Hammond High School. During his high school years, he discovered and honed his craft writing comic scripts on the Digital Webbing message boards. After graduating from Franklin College, he worked as a Teacher’s Assistant in his hometown before moving to Japan to teach English (and pay off his student loans). During that time, he managed to complete his first comic book series, Secrets & Shadows. He followed that up in 2014 with his second series, Clusterf@#k which would go on to be published by Alterna Comics and see print in 2016. He also worked on a collection of short comics called Career Criminals and two one-shots, Someday and Con-Troll. He has also done freelance work writing scripts for the comic Salty Roos and a short story for the horror anthology Tales from the Cryptic Closet 2 from Guerrilla Publishing.
His third series, Mega Centurions: Mega No More, sees him working with Secrets & Shadows team members Dexter Wee and Kote Carvajal. It is published by Scout Comics and was released in 2022. He also has a short story in the fourth edition of the Tales from the Cryptic Closet anthology.
