In 1985 Schreck and his future wife (now divorced) Diana Schutz were hired as, respectively, Administrative Director (in charge of marketing and publishing) and Editor in Chief of Comico Comics.

[7] Schreck was closely involved in the publication of titles such as Mage and Grendel, Elementals, Robotech, and Jonny Quest, was responsible for several acclaimed graphic novels including Mike Baron's Ginger Fox and Doug Wildey's Rio,[8] and secured work from such luminaries as William Messner-Loebs, Steve Rude and Dave Stevens, among many others.

[12] In addition to his work as marketing director and talent recruiter, Schreck was the editor of many titles including Frank Miller's Sin City, The Big Guy and Rusty the Boy Robot, Madman, Art Adams's Monkeyman and O'Brien, and the anthology title Dark Horse Presents which became one of the most important places for new talent to enter the field alongside well-known names doing often experimental or edgier work.

[13] Schreck was later instrumental in compelling Frank Miller to work with director Robert Rodriguez on a film version of Sin City.

For DC's Vertigo imprint he produced the award-winning Daytripper, Sweet Tooth, and the horror anthology Toe Tags, which featured a story by film director George A. Romero[19] After leaving DC in January 2009, Schreck joined IDW Publishing as a senior editor, where he also wrote the comic book series Jurassic Park: Redemption.

[20] In 2010, he was named editor-in-chief of Legendary Comics,[21] a division he co-founded with editor Greg Tumbarello, where they launched as a top ten publisher with their inaugural title Holy Terror by Frank Miller.

Other works they published include the Eisner Award-nominated Annihilator by Grant Morrison and Frazer Irving,[22] The Tower Chronicles by Matt Wagner and Simon Bisley, A Town Called Dragon by Judd Winick and Geoff Shaw, Shadow Walk by Mark Waid and Shane Davis, and Cops for Criminals by Steven Grant and Pete Woods, as well as NY Times #1 Best Selling graphic novel Pacific Rim: Tales from Year Zero, NY Times Best Seller Godzilla: Awakening, and tie-ins to Warcraft, and King Kong.

A place for these people to take root and grow... a certain amount of stepping back and compassion, just being able to listen to what it is... many times the writer or the artist you're working with, they're not quite sure what it is they want to say at this juncture.
