I know you're directing your question to Mark, but I think I can answer it.
An "in house" graphic designer is a graphic designer who works exclusively for a company. "In house" = "employee". So, rather than Mark designing the graphic himself or hiring a freelance graphic designer, one of the graphic designers that work for his company full-time created it.
