Steigerwald first worked with Top Cow Productions, colouring covers and interiors and designing most of their comic book productions. Peter also painted a number of trading cards for such popular Top Cow comics as Witchblade and Fathom. In 2003, Peter, along with many other Top Cow artists and staff, moved away from Top Cow with Michael Turner to form a new comic company known as Aspen Comics. There, Peter took on a much larger role, acting as Vice President of Publishing, as well as continuing to use his graphic design and colouring skills.

Since joining Aspen, Steigerwald has colored a great deal of comics, covers, and pin-ups for his co-worker, Michael Turner. His work with Aspen has also led him to do cover colors for many DC and Marvel comics.

Since 2010, he has been the main colorist for Joe Benitez' Lady Mechanika steampunk series.

Steigerwald has also worked on the Heroes graphic novels through his work at Aspen. He started off as just a colourist but has moved onto drawing the novels too.^[1]
