Astrology of the Crossroad
What does it look like when everything is about to change in someone’s life? This lecture will identify common timing indicators that present themselves when a client is approaching a major crossroads in life, as well as showcase chart examples from clients and public figures. Ultimately, this is a technical examination of what separates major change from more run-of-the-mill change.
Steph Koyfman is a writer and astrologer best known for her work as Lady Cazimi. Having been initiated onto this path one nodal cycle ago and practicing for half of it, her background in journalism progressed naturally into reporting on the movements of the sky, and she currently devotes the bulk of her time to helping others map the field of possibility. She is certified by the International Society of Astrological Research, and her work has appeared in Chani App and Condé Nast Traveler.

Unveiling the Decans: A Journey Through Astrology’s Hidden Layers of the Zodiac
Dive into the rich symbolism of the decans in this talk that bridges astrology with Hermetic Kabbalah, numerology, the Tarot, and ancient esoteric texts, including Ibn Ezra’s The Beginning of Wisdom, Agrippa’s Three Books of Occult Philosophy, and the Picatrix. This session focuses on practical ways to work with the decans rather than covering each one in detail. Explore how these 10-degree segments of the zodiac influence individual lives through real-world chart examples. See how planetary placements in specific decans reveal archetypal themes, spiritual lessons, and personal patterns.
Cathy Gnatek is a Certified Hellenistic Astrologer with expertise in Ancient Greek, Greek Mythology, Jungian Psychology, Tarot, IChing, existential philosophy, and nondualistic spiritual traditions. A former trial lawyer with a Master’s in Clinical Psychology, she serves on the Organization for Professional Astrology (OPA) board and previously served on the Minnesota Jung Association board. Cathy teaches Hellenistic Astrology at the University of Minnesota’s Osher Lifelong Learning Institute. She writes the New and Full Moon blog Skywriting and co-hosts a monthly Astro Meetup in St. Paul with astrologer Nicole Coenen. Passionate about integrating astrology with psychology and spirituality, Cathy brings depth and insight to her teaching and practice.

Under Morpheus’ Wing: Lucid Dreaming for Astrologers
There are places in an astrology chart where you can find the dreamer. This talk is to help the astrologer find themselves within the dream. As a practicing lucid dreamer and a speaker on lucid dreaming, dream incubation and dream practices, I wish to share how the dream work can assist astrologers. Using lucid dreaming techniques to augment astrological studies is an affective and transformative tool to integrate into the astrological practice. Basic ways to learn how to lucid dream will be shared through the lens of astrology: the current sky, personal transit activation and chart meditations will be the focus on this talk. The idea is to tap into the potential of lucid dreaming for the astrologer to use in their astrology work.
A lifelong devotee of myths, Christa Hamilton began to deepen her astrological studies and left a hermit’s cave to become an astrologer for others in 2022. Her astrology, tarot & writing are influenced by her teachers through either direct instruction or their written works: Kelly Lee Phipps, Liz Greene, Demetra George, Chris Brennan, T Susan Chang and Adam Elenbaas. She is a founding member of the Asteri Sofia Kairos Astrology collective, a contributing writer for the Astrologer’s Co+Op & a speaker in the Nightlight Speaker Series. Her astrology work is based on 1:1 client consultations and includes developing lectures and conversations on YouTube, writing long form on SubStack as well as live + online events throughout the year with the astrology collective and solo.
