Nan Rossiter was born in Mount Vernon, New York on March 31, 1964. Some of her earliest memories include exploring every corner of her Pelham neighborhood on a green bike with a banana seat and sissy bar. She also remembers wearing a hooded sweatshirt, carrying a notebook and pretending to be Harriet the Spy. Nan later moved with her family to Barkhamsted, Connecticut where she attended Northwestern Regional #7 High School. She is also a graduate of the Rhode Island School of Design.

After working in the freelance field and creating art for internationally recognized companies such as Viking, MasterCard and UPS, Nan began writing and illustrating books for children. She is the author-illustrator of Rugby & Rosie, an American Bookseller Pick of the Lists and winner of Nebraska’s Golden Sower Award, The Way Home, one of Smithsonian Magazine’s Notable Books for Children, Sugar on Snow and The Fo'c'sle, Henry Beston's "Outermost House".
