Yishai Gaster

Yishai Gaster is the founder of the ‘Constellation Way’ – Institute for the Study of Systemic Constellations, founded 2006.

He has been practicing Systemic Constellations since 1996,  training consultants and facilitators and giving seminars internationally since 2005.

To his work Yishai brings extensive clinical experience with individuals and groups as a graduate of the Chiron Center for Holistic Psychotherapy (UK) and a UKCP integrative psychotherapist (1999-2007). His organizational experience he gained from serving as a VP in Columbia Marketing, a major book company in the UK for over ten years and a consultant and trainer within the organizational field since 2007.

In 1996 he met Bert Hellinger, creator of Systemic Constellations and was profoundly inspired by his work with Family Constellations, which he immediately started to train in. 

“Seeing Hellinger’s work for the first time felt like a quantum leap in the therapy field. I could see most of the wisdom originating from the different schools of therapy, namely: Psychoanalysis, Jungian Analysis, Gestalt Psychotherapy, Psychodrama, Family therapy Body Psychotherapy, all converge into a simple and profound process.”

Born in Israel moved to London UK in his mid twenties. After living there for about 19 years, in 2005  he returned to Israel with his family where he devoted all his attention to the development of Systemic Constellations. He founded the Israeli Institute for the study of Systemic Constellations, now ‘The Constellation Way’. Today there are 18 trainers in the institute with about 80 trainees each year.

Yishai trained therapists and organizational consultants from different backgrounds and methodologies; giving seminars in the Hebrew University; Ministry of Education; to social workers in developing communities, to therapists from various backgrounds, and finding ways of mutual enrichment with other schools of therapy, namely The Israeli Academy of Focusing and The Israeli School of Biosynthesis. The ‘Constellations’ work was also integrated into the Doula and birth work where it is now accepted as an important tool in the field.  

The Constellations Way is a thriving community of diverse trainers and facilitators from different professional backgrounds who take the constellations work onward into diverse fields such as:

In Family Constellations: Constellations for Midwives, Doulas and child-birth workers, Constellations and Focusing, Constellations and Body Psychotherapy, Constellations and Loss, Constellations and Parenting, Constellations and the Feminine and more…

In Organizational Constellations: Constellations and HR, Constellations and Leadership,  Constellations career, Constellations in Research and Development, and Constellations in resolving Organizational issues. 

Internationally Yishai has given seminars and trainings in the Israel, UK, Spain and Switzerland.

Since the summer of 2016, Yishai moved with his family to Sunnyvale California where he has a practice, aspiring to continue, develop and promote Systemic Constellations with all its different aspects in different fields of society; from the caring professions to the organizational, the educational,  the political and the scientific fields. Continuing to research, develop and find new frontiers for the application of Systemic Constellations.

“With deep gratitude to all my teachers, especially Bert Hellinger, Albrecht Mahr and Jan Jacob Stam, who opened for me the way of seeing and constellating systems, and with solidarity to all teachers who seek to give onward what they have been given.”
