OnBoard is a brilliant chronicle of the rise of Black women on America's boards and the evolution of board diversity from Patricia Roberts Harris in 1971 to the present day, as seen through the eyes of a group of fearless women organized during the Summer of 2020 to create change. Merline Saintil, a former Tech COO and Robin Washington, a former CFO, were well-known in the boardrooms of America. During an ordinary phone call between the two women, something extraordinary happened– the movement to create an organization to expand the opportunity and exposure of Black women who can impact America's boards. Black Women on Boards, the now global organization of 200+ members, was conceived at that moment.
