Meet Diane
F. Grannum
Diane F. Grannum is a lifelong advocate for children, families, and the transformative power of early education. Born in Peekskill, New York, and currently based in Baldwin, Long Island, Diane’s life and career have spanned the diverse boroughs of Brooklyn, Queens, and beyond—each shaping her understanding of the communities she has passionately served.
With over three decades of experience as an educator and administrator in the New York City Department of Education, Diane has worn many hats: English teacher, grant writer, instructional leader, and ultimately, Regional Director of Early Childhood. Her work helped build and sustain Pre-K programs that reached tens of thousands of children across the city—programs she views as foundational to a child’s growth.
Her book, Creating the Universe: Universal Pre-K in the New York City Public School System 1995–2007, was born from a deep conviction and a fierce love for the field she helped shape. As early childhood programs faced political threats nearly two decades after their inception, Diane knew she had to speak up, not just as a professional but as a witness to their extraordinary impact.
Diane’s writing is informed by her career and personal journey. She reflects on what she lacked as a child, including early guidance, structured support, and emotionally intelligent educators. She uses her voice to advocate for every child to have access to what she did not.
Outside of her work in education and writing, Diane is a proud Realtor with EXIT Realty Premier, a lifelong learner, and a lover of travel, cooking, gardening, decorating, and astrology—an interest lovingly passed down from her brilliant mother.
Diane is also a member of the Committee of Supervisors and Administrators (CSA), an associate of the United Federation of Teachers (UFT), and a dedicated community leader committed to uplifting the lives of children and families across New York and beyond.
Through her words, Diane continues to teach, inspire, and fight for a future in which every child has a chance to thrive—starting with the very first years of life.
