In 1948, they moved to the United States, where he earned a Bachelor of Arts and a Master of Arts from the University of Chicago. He studied at the Yale School of Drama for one year before joining the U.S. Army.^[4] Grosbard became a naturalized citizen in 1954.^[1]

After directing The Days and Nights of BeeBee Fenstermaker off-Broadway, he earned his first Broadway credit with The Subject Was Roses, for which he was nominated for the Tony Award for Best Direction of a Play in 1964. The same year, he won the Obie Award for Best Direction, and the Drama Desk Award for Outstanding Director of a Play for an off-Broadway revival of the Arthur Miller play, A View from the Bridge, for which Dustin Hoffman served as stage manager and assistant director.^[5]

Grosbard's additional Broadway credits include Miller's The Price; David Mamet's American Buffalo, which earned him Tony and Drama Desk Award nominations; Woody Allen's The Floating Light Bulb; and a revival of Paddy Chayefsky's The Tenth Man.

In Hollywood, Grosbard worked as an assistant director on Splendor in the Grass, West Side Story, The Hustler, The Miracle Worker and The Pawnbroker.^[1] He directed the screen adaptation of The Subject Was Roses, Who Is Harry Kellerman and Why Is He Saying Those Terrible Things About Me?, Straight Time, True Confessions, Falling in Love, Georgia and The Deep End of the Ocean.
