Dr. Lipschitz, Psy.D. is Louis Litt's psychotherapist. He was mentioned in the episode "Know When to Fold 'Em", when Louis had phone therapy with the doctor, and again in the episode "Pound of Flesh", just before Louis was about to go on stage.
In a Suits Recruits video, Louis stated that Lipschitz's motto is: "If you set your goals, your dreams will come true".
Dr. Lipschitz made his first physical appearance in "The Statue".
