Experience

Karissa provides psychological assessment and tailored therapy through her private practice, Lotus Psychology Aotearoa. She works with private clients as well as those accessing care through funded pathways, including support for victims of crime, regional health networks, and injury cover.

Her clinical background spans primary mental health and community support services, where she has delivered both individual and couples therapy. She has extensive experience helping people navigate deeply challenging life experiences, including histories of abuse and acute emotional distress. Alongside routine therapeutic care, she is experienced in supporting individuals through immediate mental health crises and managing high-risk situations with calm, structured support.

Before establishing her practice, Karissa worked in secondary education, which gives her a practical understanding of human development, learning, and environmental stressors. She combines this background with advanced behavioural science and specialised trauma care to deliver grounded, compassionate, and effective psychological support.
