Yitzhak has lived in Jerusalem in the past of 43 years and is part of the professional psychotherapist landscape of the city. Since 2008 he is pioneering a new field of practice of “protection” which has emerged during his clinical practice, vie dialogue groups between Palestinians and Israelis, as a co-founder of Art of Protection, and most recently as a psychologist and member of intercultural community created in Jerusalem after the National Protest in Israel in 2011. With his Jewish and Mexican identity, he has developed mastery in intercultural relationships. In the last three years he has developed theoretical and practical tools for a better understanding of the essence of relationships, in particular those between victims and perpetrators, people and groups, as well as conflictual relationships. Yitzhak is an Elder of Living Wholeness Institute, a founding Steward of Axladitsa-Avatakia and a proud grandpa of Danielle, Jonathan, Itamar, Shira, Nadav, Ruth, Eran and Ido.
