Larry Postaer, Steffan and Jeremy Postaer

Growing up Postaer was like growing up in an ad agency, says Steffan Postaer, chairman and chief creative officer of Euro RSCG in Chicago. His father, Larry Postaer, founded Rubin Postaer & Associates (now RPA), mother Christine Montet is an art buyer for Foote Cone & Belding Chicago, younger brother Jeremy is executive creative director and writer at JWT, and half-brother Daniel Postaer is a creative at the DMG agency in China.

“It was freaky, the amount of synergy that we had in our family,” Steffan says.

Though dad is well-established in the pantheon of advertising greats for spots such as Honda’s “Art Gallery” and “Eraser,” the sons are doing very well on their own.
