Leaders of various tribes (business, community, home) who are looking to be provoked into insights from unexpected quarters. I enjoy speaking to senior leadership teams in multinational organisations and professional firms to 'pop' their thinking to a new level, and have found great satisfaction with courageous leaders who work one-on-one with me to deep dive into themselves so as to function at a higher level.

About My Business:


Dr Yvonne Sum CSP ACC transforms leaders of tomorrow ... today. Her presentations help people recognise simple things they may have taken for granted. You cannot help but become more present as she weaves you through connected moments of bliss. In doing so, your senses are heightened to better understand yourself and those around you, resulting in more open communications, interesting and counterintuitive learning partnerships, more innovative possibilities, and simple joys. Through her own transformational experience as a dentist, RAAF officer, executive coach, leadership facilitator & speaker, author, business partner, wife and mother of two, Yvonne has honed her gift of helping others clarify useful behavioural frameworks across various contexts so that we may choose to easily deploy them in our daily lives. She consistently provokes senior business leaders to ‘lose their minds and come to their senses’ by integrating their leadership lessons at home successfully back into the work tribe. Inspired leaders that consciously lead a great life invariably leave a legacy of authenticity where peace can reign even in the chaos of change, where passion and spirit is fully re-engaged in tribes in business, communities and families. Yvonne’s breadth of international experience and clientele span across Australia, the USA and Asia Pacific. She has presented alongside Edward de Bono, Howard Gardner, Tony Buzan, David Perkins, Glenn Capelli and Colin James. Start Kidding Yourself - Learning Leadership from your Home Tribe is her first solo book due out in 2012, and she has contributed to two other books: Emerging Trends in Professional Selling Vol 1, & Inspired Children. She lives on Sydney Harbour with her husband , 2 children and a dog.
