Online training program – including online training through WhatsApp – for more than 200 professional caregivers working in Gaza and the West Bank: aid workers, doctors, teachers, psychologists, therapists, speech therapists, musicians and other (mental health) professionals. We train them in a trauma-informed approach. To better understand and support themselves and others during and after traumatic experiences. To prevent severe traumatization during times of extreme violence, genocide, and war. This is a combined training with Sounds of Change’s training on the use of music with traumatized people.
