Ten years ago, Margie made the big decision to give up her career as an Executive Recruiter. It was something she had done for 15 years. Despite struggling at High School and not being confident she would be accepted into Uni, let alone graduate, she did. And more than that, she received a Distinction for her thesis investigating the Well-being and Performance of Male Executives. Margie has a deep interest in Mental Health, largely due to losing her 69 year old father to Mental Health difficulty in her teens. She then lost her brother who was also struggling. These events led to a strong interest in supporting Men – not only with building their sense of self-worth, but also their personal and professional potential. In a previous life Margie trained as a performer (but realised she could neither sing or act!), and still draws on this background when running workshops and presentations. A self-described fitness fanatic, out of hours Margie enjoys spin cycling, yoga, mindfulness, writing and mystery documentaries.
