Terence Osorio is a justice and peace worker whose activism dates back to college days and nurtured by various engagements over the years with civil society organizations doing advocacy work on human rights and environmental rights, peacebuilding, and facilitating organizational development. This includes working as regional coordinator of the Hong Kong-based Asian Center for the Progress of Peoples.  She brings her rich experience of coordination and networking at both national and regional levels, as well as her module writing and documentation skills, into her role in Green Releaf.


Terence did her master’s degree in Social Services and Development at the Asian Social Institute a few years after she left religious life.  Her exposure to marginalized communities during her years as a religious and church worker, however, developed in her a strong bias for capacity-building, formation/training and development, and research.  Terence also has her bachelor’s degree in Foreign Service, a certificate in Religious Studies and masteral units in Fiscal Studies.


After a much-needed sabbatical in 2015-2016 and the release of Laudato Si (Pope Francis’ encyclical), Terence decided to focus on care for the earth and found particular resonance with regenerative solutions for the wholistic and holistic development of peoples and the earth.


Grounded in a firm belief that “everything is everywhere” and “as within so without”, Terence tries to exemplify in her own life what it means to co-create with the Universe.  She is passionate about helping both individuals and collective in their inner journey, and bringing the gifts of this journey to the service of others and the planet.
