Marchowsky's love for dance stemmed from an early age; enthralled by a ballet school near her house, she begged her mother to enroll her.
At this time her mother pulled her from the school and took her to Anita Zahn to train in Duncan Dance at Carnegie Hall.
Marchowsky continued her studies with Mehlman through the following winter, until at the age of 12, she attended a concert by Martha Graham, which enthralled the young dancer and exposed her to culture unlike she had seen before.
As a Jewish girl, Marchowsky felt that Graham and her modern dance technique steeped her in culture.
Had to be professional, you were striving for the whole family, simply because they were so deprived of position by being a Jew…”[2] Though Marchowsky was profoundly shaped by Graham's technique and choreography, she eventually began to expand into her own choreographic ventures.
She did establish her own company, the Marie Marchowsky Dance Theatre Company, which made their Broadway debut in a concert at the New York Times Hall, showcasing works to include: Image of Obsession by Herbert Haufrecht, Foreboding by John Cage, Labyrinth by David Diamond, and seven solo personal works.
