Greg completed his undergraduate and higher degree training in psychology over the course of a decade whilst working as a full-time secondary school teacher. Since registration, he progressed to senior psychologist positions across sectors (Department of Education and Training), and public mental health including roles in early psychosis and community mental health services. Alongside, he has worked in group private practice (Kaye Frankcom and Associates) and currently co-partners his own practice. Interspersed, Greg held a position as a research officer for headspace National leading an evidence-based review of a national mental health initiative for secondary schools (MindMatters), and further, a scoping review to guide the training for Mental Health clinicians working in schools.

Greg’s practice extends to professional and semi-professional sports men and women. He has had a long professional and research interest in the nexus between mental health and high-performance sports. He was one of the first clinically trained psychologist to work full time within an AFL club using a clinical sports psychology framework across player and staff welfare, performance, and recruitment.

Since joining Cairnmillar in 2019, Greg has had broad influence on preparing graduate trainees for the demands of modern professional practice through lecturing, placement and unit co-ordination, and also research supervision. He lectures primarily in psychological assessment, treatment models and practices. He has been particularly active in developing graduate level learning in Acceptance & Commitment Therapy (ACT). His area of research investigates the nature, measurement and application of psychological flexibility, a contemporary metric for psychological health and resilience.
