Wendy Rhoades

Played by: Maggie Siff in Billions

A psychiatrist by trade, Wendy Rhoades combines an avid intellect with a keen understanding of human nature. She used those skills to help Bobby Axelrod build his hedge fund from the ground up and now works as the company's star in-house performance coach. Wendy joined Axe Capital long before Chuck became the U.S. Attorney and she refuses to sacrifice her lucrative career for her husband's crusade.
