Deborah Houlding, founder of the STA School, is based in the UK and has worked as an astrological consultant since the late 1980s. Her articles on horary have been translated into many languages and have appeared in numerous international journals. She was the founder of Ascella Publications (specialised in the republication of traditional astrology texts), editor of
The Traditional Astrologer magazine (1993 to 2000), and creator of the
Skyscript astrology website. She has also worked as the Horary Editor for the
Astrological Association of Great Britain's Journal, and the The Mountain Astrologer magazine, which presented her serialised 'Introduction to Horary Astrology' in 2013.
Deborah's book, The Houses: Temples of the Sky is regarded as an essential text for anyone seeking an informed knowledge of the development and practical use of astrological houses. It is available in Czech, English, German, Italian, Japanese and Turkish. Deborah is also the author, with Oner Doser, of Soru Astrolojisi: Horary Astrology (Astroloji Okulu, 2015).
Deborah established her own horary course in 1996, in a completely unique format, which demonstrates theoretical principles through their application to chart work. This approach was motivated by her observation that many astrologers who gain qualifications in horary courses, admit to knowing the theory, but lacking the confidence to apply the techniques in practice.
In 2010 Deborah was awarded the Charles Harvey Award by The Astrological Association of Great Britain in recognition of her 'exceptional service to astrology'. In 2012 she received the Jayavidya Cultural Association International Award for her cultural contributions to the field of astrology. In 2018 Deborah received the UAC Marion March Regulus Award for 'advancing the theory and understanding of astrology'.
