Angie Mangino, a former investigative reporter for the Staten Island Register weekly newspaper, is a freelance journalist who has been providing quality service to editors since 1995. Her publications online and in print include articles on a variety of subjects, essays, and book reviews as well as her contributions to anthologies and an academic book. In 2013 the American Society of Journalists and Authors (ASJA) accepted her as a member. She critiques unpublished manuscripts for other authors and is a copy editor.

Having lived in Tottenville since 1978, the Council on the Arts & Humanities Staten Island awarded a grant to her in 1999 to research the history of Tottenville to conduct an interactive workshop in the community. In 2000 the New York Public Library sponsored another workshop at the Tottenville Branch, and in 2002 the N.Y. State Assembly named her a Staten Island Woman in History. She was interviewed on the 50 Plus show at the local Community TV station and included in Gabe Pressman's report on Tottenville on WNBC.
