Join Demetra for live astrology workshops and conference appearances.


July 17 – August 10, 2023

How to Calculate a Chart by Hand

Dedicated to Heliodora, mathematike, 2nd c CE.

Mathematikos is the ancient Greek word that was used to refer to an astrologer because they were always doing numbers in order to erect a chart. This is the first and most fundamental act of the astrological tradition. Tap into this esteemed lineage and preserve it by learning the almost lost art of calculating and drawing up an astrological chart by hand. The process becomes a meditation in its own right and helps you to embody the chart before even encountering the client.

Sliding into a beginner’s state of mind, Demetra presents her signature style clear, orderly, detailed and thorough step-by-step teaching.  Using only an Ephemeris, Table of Houses, and basic arithmetic, master how to determine the exact degrees for planets’ longitude and declination, and the MC, Ascendant, and intermediate house cusps. Then draw up the chart in the Placidus, Whole Sign, Equal, and Porphyry systems.

The basic astronomy of the great circles is interspersed into each lesson in order to visualize and better understand what the degrees of planets and sensitive points actually represent in the sky and how they change with small increments of time. A Bonus Class illustrates how to use Interpolation Tables and calculate the both the day and night Lot/Part of Fortune.

Fully worked out calculations for each step of the process are provided for the class example, additional practice charts, a homework chart, and a template for instructional worksheets. Online links are given for the data and reference materials, as well as  online self-checks for degree/decimal conversions.

This class will prepare you for taking the calculation portions of the the AFA Professional Exam and NCGR Level 1 Certification Exam.


6+ hours of instruction. Self-guided class with pre-recorded lessons, exercises and examples.

Two live Q&A sessions with Demetra on July 27 and August 10 at 11am Pacific time.

The History of Astrology

Discover astrology’s rich history and tradition beginning with ancient Babylonia, its consolidation in Egypt, the diffusion of astrology through the Roman Empire and sojourn into the Persian and Islamic Republics, to its 12th Century reintroduction into Medieval Europe.

In this engaging and enlightening seminar the interface between astrology and ancient philosophy, religion, myth, and politics is deeply explored. How the Gnostic, Hermetic, Neoplatonic, Christian, and Jewish traditions regarded one’s life through the reflection of the stars and the concept of fate and free will is brilliantly articulated.

Includes breakout session on the unique history of astrology in the US in the 19th and 20th Centuries.

This course will leave you in awe with a rich context for astrology’s place in our history, and a new awareness of the profundity of the astrological tradition and its legacy to the human imagination.

Intro to Hellenistic Astrology

Learn the Hellenistic approach to natal chart reading. Demetra introduces the concept of “planetary condition” as practiced by ancient astrologers. You’ll learn the first steps towards making a judgment about a planet’s relative ease or difficulty in expressing its significations. Includes the first set of tools including: sect, traditional planetary rulership, the use of whole sign houses, solar phase, intro to aspect configurations, and making a judgment. This course prepares students to pursue further studies to learn a more complete set of Hellenistic techniques for evaluating planetary condition, either through self study or advanced courses with Demetra.

in-person retreat

December 1-3, 2023 Mythic AsteRoid Signatures Retreat in Palm Springs, CA

Join Demetra for a three-day in-person intensive working with the mythic-named asteroids drawn from several different cultural traditions. Looking to both large and smaller asteroid lists (included with registration) and your own chart, Demetra will guide you to identify personal mythic deities and motifs, as well as significant names and places.

Guidance will be given for researching myth, finding patterns, and deriving meaning and illumination from the universal archetypal themes that correspond to the experiences of individual lives. Asteroids can be linked to the notion of daimons in ancient cosmologies and can provide a focal point for meditation, ritual, healing, and spirit guides.

Hands-on and interactive. The daily format will include lectures, small group work with your own charts, sharing insights and correlations, as well as ample opportunity throughout the day for Q&A. Registration limited for a more personalized experience.
