Born in rural Wisconsin in 1959, Cicero graduated from the University of Wisconsin—Milwaukee with a Bachelor's Degree in Fine Arts in 1982. She worked as an entertainer, typesetter, editor, commercial artist, and computer graphics illustrator. She met her husband Chic Cicero in the early 1980s.
Along with her husband, Cicero has co-authored several successful books on the Golden Dawn, Tarot, Kabbalah, and the Western mystery tradition including The Essential Golden Dawn, which won a COVR award in 2004 as one of the year's best titles in the field of magic. Together, the Ciceros have edited, annotated and added new material to recent editions of classic magical texts by Israel Regardie including The Middle Pillar, A Garden of Pomegranates, and The Tree of Life. At the encouragement of Israel Regardie she painted The Golden Dawn Magical Tarot.
Cicero is a Rosicrucian and a Martinist. She was initiated into a modern Order in the tradition of the Hermetic Order of the Golden Dawn in 1983. Together, Cicero and her husband are two of the G.H. Chiefs of the contemporary Order of the same name, which claims initiatory lineage to the original Golden Dawn through Israel Regardie. They are the most visible members of the modern Order. In 1988, The Hermetic Order of the Golden Dawn, Inc. was incorporated in the State of Florida.
