Dr Marié Venn is a medical doctor with 9 years of experience leading acute psychiatric care at a district, public service hospital in Cape Town. During this time she worked closely with nurses, security and auxiliary personnel on a daily basis. There was a distinct and urgent need for improvement in communication skills, de-escalation tactics and insight. She initiated and implemented an after-hours de-escalation training and support programme for hospital security guards. Conquer Crisis is a focused continuation of her early interventions.
