Jadranka Ćoić was born and raised in Croatia and moved to London in 1991. Her astrological training began with the Faculty of Astrological Studies, continued with the School of Traditional Astrology, and culminated in the QHP (Qualifying Horary Practitioner) Diploma. For many years she served as Treasurer of the Astrological Association of Great Britain and as Beginner's Class Tutor for the Astrological Lodge of London, where she has also organised the Lodge's annual Astrology and Healing Seminar. Alongside her astrological work, she grows vegetables on her allotment following Moon cycles, and her interest in herbs and medical astrology informs her broader approach to the subject.
