Workshop
The role of Motivational Interviewing in working with family violence (March 2020, Melbourne)
An innovative and engaging two-day workshop to build MI understanding and skills
Ken McMaster (NZ) and Helen Mentha (Australia), internationally known trainers in MI, will take an exploratory approach to expand thinking and sharpen focus regarding MI concepts, skills and applications in relation to intervention in family violence. They will integrate concepts from positive psychology, cognitive science and grit to design and facilitate powerful learning experiences. Come expecting to learn something new, try something different, and walk away feeling energized and challenged.
