A psychologist by profession and a social entrepreneur by heart, Lior believes that psychologists have a responsibility for the well-being of society. The youngest child in a family of Moroccan descent, Lior was born and raised in the coastal city of Ashdod. While a student at Tel Aviv University, Lior led Asafsouf, a social incubator that was part of the Bat Yam Biennale of Landscape Urbanism. The group, formed by artists, architects, and social activists, challenged the relationships between the municipality, the local community, and Abarbanel, a mental hospital located in the city. The group created projects to contribute to the wellbeing of patients and produced cultural events that were open to public inside the hospital. In the summer of 2011, during the social justice protests, Lior co-founded and led the Movement for Public Psychological Services, which brought together representatives of the different sectors in psychology to promote better public services. The lack of public psychological services, especially for young people, brought him to co-found Headspace, an early intervention and prevention center for youth aged 12-25, together with Enosh, the Israeli mental health association, the National Insurance Institute of Israel, the Bat Yam municipality and private donors. Today Lior serves as the clinical director of Headspace Israel and also teaches an Introspection for Designers course at Shenkar Academy. Lior is striving to make public psychological services accessible, and is constantly involved in creating new, innovative programs in this field.
