John Cassaday is a comic book artist who has worked with Marvel Comics for several titles now. He has been part of more than a few high profile projects from the re-introduction of Captain America, the Astonishing X-Men and the Planetary series with Warren Ellis.

John started his dream by simply taking his portfolio to the San Diego Comic Convention, where all of the greatest artists show off their work. He was able to run into Mark Waid, who immediately knew that he would be a pro in no time.

Waid remarked that "I can say honestly that I've never seen a better convention portfolio ever, and I knew the moment I looked at his work that he'd be a pro in short order." After a month from that San Diego Convention day, Cassaday started to get several phone calls about job offers as a comic book artist.

His first work was with Dark Horse comics when he worked on the comic book, "Ghost". Cassaday was able to do a couple of mini-series for the X-Men/Alpha Flight series. He also had experience with Union Jack and Desperadoes. He was able to collaborate with comic book writer Warren Ellis for the very first time in the comic book "Planetary" which is now a timeless piece of comic book literature.

His big break was when he was commissioned to be the artist for the re-launching of "Captain America" which was under the Marvel Knights banner. The different covers that he illustrated for these particular series were inspired by WW2 wartime propaganda posters.

The series was actually critically praised by the different fans and instead of just doing the first six issues, Joe Quesada told Cassaday that he would like him to be part of the whole series as much as possible at the soonest possible time.  When he was doing an interview with Silverbullets Comics, Cassaday said, "I only signed on to do the first six issues. But Joe made it clear to me that he'd like me back whenever possible. It's open-ended."

He is a perfectionist as he acts as both the penciler and the inker for his work. Even though there have been complaints about the lateness of his work translating to the release of the titles being late as well, he said that he is able to produce around 5 pages of work a week and that the lateness of the release of the books has absolutely nothing to do with him.
