Charlotte Santiago - MPsych(Clin)

Consultant + Mental Health & Wellbeing Specialist

Meet our passionate and practical wellbeing specialist - Charlotte. Originally from France, and with a Masters degree in clinical psychology, Charlotte has been a Clinical Counsellor and a Gambling Councillor as well as a Medical Assessor for Southern Cross. She excels at working with individuals, groups and communities to improve mental health. She is highly skilled at examining and identifying issues including substance abuse, bullying, anger management and depression. 
Charlotte’s passion for Mental Health and Wellbeing in New Zealand businesses stems from her concern that New Zealand has one of the highest rates of suicide and depression in the world – and yet we have very little practical measures, or systems, in place in our workplaces to minimise them. 
Charlotte works with our clients to acknowledge, identify, assess, control and monitor the Mental Health and Wellbeing hazards in workplaces, ensuring workers are happy and healthy at work.
