Lady Rhea has been a Wiccan High Priestess in the Gardnerian tradition since 1972. She is known as the "Witch Queen of New York" and has been an occult shop owner since 1982, when she opened Enchantments Inc. with Lady Miw (aka Carol Bulzone). In 1992, Lady Rhea opened Magickal Realms (Enchanted Candle Shoppe Inc.) in Greenwich Village, later relocating to The Bronx, where she co-operates the shop with Lady Zoradia.
Lady Rhea, who is openlylesbian, co-founded the Minoan Brotherhood with Lord Gwyddion (aka Edmund Buczynski), and later co-founded the Minoan Sisterhood with Lady Miw. On the Magickal Realms website, Rhea states that she is "of the Gardnerian and Welsh Tradition but considers herself and all of her children as Edwardians from her High Priest and teacher Edmund Buczynski (Lord Gwyddion)." Her children—that is, Wiccans who have studied under her and been initiated into the craft—include Lexa Roséan.
In 2004, Lady Rhea published her book The Enchanted Candle, based on the hand-carved, embellished candles she has created for years. She published a second book, The Enchanted Formulary: Blending Magickal Oils for Love, Prosperity, and Healing, in September 2006.
