[2][3] Zeena was born in San Francisco on November 19 1963 to Anton LaVey and Diane Hegarty, co-founders of the Church of Satan.

[7] Anton LaVey biographer, Burton H. Wolf described a thirteen-year-old Zeena in his introduction to her father's The Satanic Bible as "Zeena, remembered by people who saw the famous photo of the Satanic Church baptism as a tiny tot, but now a gorgeously developed teenager attracting a growing pack of wolves, human male variety.

In 2019, both parties issued a jointly written public statement on their respective websites stating, "[...]in 2015, after having been separated since 2007, we agreed to amicably divorce.[...

"[11] Zeena chose to keep her married name stating in an FAQ on her website that she would not reinstate her born surname (LaVey) "due to the heavy weight of negative karma that travels with it.

[13] In addition to CCSF's Drama Department, she also received instruction from Stella Adler Studio of Acting, Eric Morris acting coach, Viola Spolin's student Marcia Kimmell of The Next Stage Improvisation Theater San Francisco, and the San Francisco School of Dramatic Arts.

[15][16] During the 1960s and 1970s, Anger transmitted the influences of Curtis Harrington, Jean Cocteau, and Maya Deren on his own work to Zeena during her childhood and adolescence.

[21] Interviews, articles and reviews from 2011 to 2013 referred to her conversion to Tibetan Tantric Buddhism in the Drikung, Karma Kagyu and Nyingma lineages, as well as her status as the spiritual leader of the Sethian Liberation Movement (SLM).

[27] She also appeared on the Sally Jessy Raphael Show, alongside her husband, debating several Christians who were invited onto the program to expound their own religious views.

[30][31] Zeena sat alongside the Temple of Set founder/High Priest Michael A. Aquino, and repeatedly denied the rumors circulating at the time that the Church of Satan was in any way involved with ritual abuse.

She also called the testimony of claimants involved into question, asking them rhetorically why, if people were being forced to give birth to babies for sacrificial rituals, no remains had ever been found.

[27] Zeena was also in regular contact with law enforcement agencies and personnel, including Detective Patrick Metoyer of the LAPD[34] and Robert D. Hicks, law-enforcement specialist with the Virginia Department of Criminal Justice Services and author of several precedent-setting treatises[35] including In Pursuit of Satan: The Police and The Occult.

Prior to Zeena's dialogs and meetings with government agencies, police and law enforcement had only a very limited knowledge of Satanism.

[37][34] In a March 2013 interview televised by Network Awesome, Zeena spoke for the first time on camera about her experiences with media during the "Satanic Panic" years.

[38] In an August 2024 two-part interview totalling nearly three hours for the Jordan Peterson YouTube podcast, Zeena explained in detail her early life and role within the Church of Satan as High Priestess and its first public spokesperson, her reasons for severing ties with her father and his organization, and her ultimate path to where she is today as practitioner and teacher of Tibetan tantric Buddhism.

As she toured the United States on behalf of the Church of Satan, Zeena's crisis of faith reached its highpoint when she learned that most of her father's self-created legend was based on lies and that many of his works were plagiarized.

When jealousy and spite motivated Anton LaVey and his administrator Densley-Barton to actually endanger Zeena's life, she could no longer continue to cover up her progenitor's true character in good conscience.

In a December 30, 1990, open letter to Michael A. Aquino of the Temple of Set, she stated: "In light of all of the factors herein, I also officially severed my given surname [LaVey] and now prefer to be known only as Zeena.

Temple of Set sources have claimed that eighteen Initiates have resigned while others have estimated the number at closer to sixty (including several Orders, Elements, and members of the Adept and Setian degrees).

It explains that "Since 2004 Phoenix provides spiritual healing for victims of exploitative pseudo-religious organizations, former gang members, whistle-blowing ex-employees of corrupt corporations and governmental agencies, relatives of the violently mentally ill, and survivors of all forms of institutional abuse, including secretly abused children and spouses of prominent personalities."

[55] On March 18, 2013, Network Awesome's daily program opened with an exclusive original production featuring Zeena Schreck's first one-on-one televised interview in 22 years,[56] conducted by artist Jen Ray.

[58] Other features in the day's program included archival interviews of Zeena and documentaries relating to her current spiritual pursuits and practices.

In 2011, a conspiracy theory in a vein similar to that of the Ted Cruz–Zodiac meme arose online, conflating Zeena with popular singer-songwriter Taylor Swift.

[61][62][63][64] On June 14, 2023, Teen Vogue reported it as one of the "8 most popular conspiracy theories in history"[65] On August 8, 1988, a large gathering converged on the Strand Theater in San Francisco for the film debut of a mockumentary about Charles Manson.

[70] She served as composer, vocalist, musician and graphic designer on the Radio Werewolf recordings "Songs for the End of the World", "The Lightning and the Sun", "Bring Me The Head of Geraldo Rivera", "Boots/Witchcraft"[71] and "Love Conquers All."

[78] On November 8, 2013, the visual art performance biennial Performa presented Zeena accompanied by New York musician Hisham Bharoocha (first percussion) and Danish musician Anders Hermund (second percussion), for a vocal based work that tapped into the ritual use of sacred syllables from Vajrayana, Shaktism and Sethian-Typhonian left-way tantric practices, "originating from emptiness, gradually transforming into a sound and voice collage on a stage set design by Frank Haines.

Dead center, with hands held in the Mudra position, stood the seemingly twenty-foot tall goddess Zeena.

Bharoocha lit incense that swept through the audience as Zeena's commanding gaze pierced us all (everyone I talked to after the show swore she was staring directly at them).

Murnau: A Ghost Story in Six Acts," inspired by news reports that the director's head had been stolen from his grave under mysterious circumstances.
