Rock and roller–turned–Portland, Oregon, decorator Max Humphrey taught himself the classic design rules so he could break them — when he feels like it.

Humphrey threw himself into studying interior design, eventually becoming a partner at Los Angeles’s Burnham Design. Last year, the 37-year-old opened his own firm in Portland, Oregon, where he specializes in lively, layered family homes for executives at Nike and Intel. It’s all true to his rock roots: “Style is about knowing who you are and what you want to say — and not giving a damn.”
