“Quote or Hero text” – Justin Harrison

Justin has worked in the fields of family support, relationship counselling, and psychological therapy for two decades. In addition to practise work Justin has published and presented research on positive behavioural support, moral reasoning and religious cognition in numerous journals and international conferences. Justin taught Developmental Psychology, Research Methods and Cognitive Psychology at a regional University for nearly a decade.

Balancing academic rigour with humanistic faith in human potential, Justin’s therapy work is informed by behavioural, cognitive, narrative and psychodynamic perspectives, underpinned by the belief that people are able to heal themselves if provided appropriate support and resources. Justin’s work is also informed by his practise/teaching in the martial arts, gardening and an abiding reverence for the natural world. In sum, people are like plants, if they can find the light, they’ll grow towards it.

Justin is available to provide cognitive and educational assessment, treatment for mild to moderate mental health problems, non-medical sexual difficulties, couple’s interventions, and parental support for challenging behaviours for families of children with or without a disability. Having completed training in psychedelic assisted therapies in 2022, Justin is also available to provide support for integration of non-ordinary states of consciousness in a harm minimisation framework.
