Born in the States to peripatetic British parents, Jeannine grew up on the East Coast and Canada. Her sensibility reflects the dual US/UK citizenship facilitating her work on both sides of the pond. She calls New York City home.

She has written scripts for MGM, Columbia Pictures, Universal, Twentieth Century Fox, Turner Films, Focus Features, HBO, and numerous independent producers. Known for writing strong women and complex pieces with political scope, her work dwells in half a dozen countries and as many centuries, spanning from the Middle Ages to the present and ranging in subject matter from medieval misogyny to enlightened philogyny, the Wild West to the World Wars, cubism to chaos theory, spying to surfing. 

Her work has been recognized with the Laurel Screenwriting Award, as a Nicholl Fellowship Finalist, and selection for the éQuinoxe Writer’s Lab in association with the Sundance Institute, Bordeaux, France. Film projects have been awarded development funding from the British Film Institute and Filmforderungsanstalt. Stage work has been selected for support from New York Stage and Film, ASCAP (American Society of Composers, Authors and Publishers), National Alliance for Musical Theatre (NAMT), and the American Musical Theatre Project at Northwestern (AMPT).

Jeannine has a B.A. in English and History from Yale, furthered her studies in theatre and dramatic literature at the University of California, Berkeley, and received an MFA in film from Columbia University School of the Arts. She considers her greatest mentor and collaborator her beloved late husband, the gifted writer Guy Gallo.
