Kolins’ interest in drawing and comics began when he was around 10 years old as an avid comic book reader in the late 1970s. In the 1980s, he worked under Dennis Jensen, and then under Kim Demulder and Bart Sears. In 1991 he went to New York to the Joe Kubert School of Cartoon and Graphic Art where he attended 2 years and then got a job with Valiant Comics. He was then hired as a Romita Raider (in house art corrections under John Romita Sr.) at Marvel Comics.
Kolins announced his move from Marvel in 2007 and that he had been talking to Geoff Johns about a future project.
Kolins has attended every San Diego Comic-Con for a decade or more.
