When asked what compelled her to make this documentary, Mazzio points to the absence of strong female role models for young girls. Mazzio hoped that by making A Hero for Daisy: A Documentary (1999), she would be preserving a pivotal moment in the struggle for women's rights, and championing the courageous acts of true heroes-the type of hero that would serve as an admirable role model for her young daughter Daisy.
Mary Mazzio's presentation of A Hero for Daisy is an integral addition to the Kravis Institute's series The Role of Parents and Coaches in Developing Leadership in Athletes.
