Denise (Deni) Dietz was born in New York City (Manhattan). She had a short-lived singing career, taught briefly at Flushing High School in New York and worked as an extra for Paramount. Her sister Eileen Dietz, who had a starring role in General Hospital, has influenced her writing career, inspiring two novels about behind-the-scenes stardom and television, The Wishing Star (2003) and Fifty Cents For Your Soul (2002).

The first book in her Diet Club Mystery series, Throw Darts at a Cheesecake, was inspired by her part-time job as a Weight Watchers lecturer. Diet club members are murdered when they reach their desired weight. It was followed by Beat Up A Cookie, dedicated to Alan Alda and concerning a group of M*A*S*H* addicts. Another mystery featuring diet club leader Ellie Bernstein is Chain a Lamb Chop to the Bed (Five Star Mysteries, 2005).

Her first Ingrid Beaumont Mystery, co-starring Hitchcock the Dog, was Footprints in the Butter, with some of the profits donated to Canine Companions, an organization that trains dogs to help the handicapped. Her historical romances include Dream Angel, Dream Dance and A Highwayman Comes Riding. Written under the name Denise Dietz Wiley, her generational saga The Rainbow's Foot includes the Cripple Creek gold rush, the Ludlow Massacre and Colorado's silent film industry. Her forthcoming mystery Eye of Newt features a contemporary witch and three witches who live in Salem. Her short story Yes We Have No Bananas is contained in the 2003 Silver Dagger anthology Criminal Appetites.

Dietz married to Gordon Aalborg, who has published romances under the pseudonym Victoria Gordon. They met online 'through a writers loop', and have collaborated a romantic suspense novel, Finding Bess, written on-line, when he was living in Australia and she was living in the United States.
