Our Global Healing and Human Rights clinical trainees join PTR with a strong commitment to human rights and social justice. They have a keen interest in providing trauma-informed, culturally aware and linguistically accessible mental health care for international survivors of human rights abuses, and contributing to the psychosocial well-being of refugee and asylum seeking populations. As a group they bring to PTR a rich diversity of languages, cultural backgrounds, and international and professional experiences.
