Who is the Guy Who Knows? 

Guy Who Knows is a well-known figure on the Upper East Side.

He moved to New York in his younger years and found himself in a key position, surrounded by endless personalities with one thing in common: living on the Upper East Side. His day-to-day interactions, conversations, and experiences all made him understand how interesting and different life on Madison Avenue truly is.

Mixing comedy with a cynical point of view, he wrote his first book, The Untold Stories of Madison Avenue.

Guy Who Knows still lives in New York and has no plans to leave anytime soon.
