In her 20s she was awarded her first board appointment and has gone on to hold several other directorships in both businesses and NGOs.

In 2000, demoralised by the lack of ethical business conduct in the electronics sector at that time, after gaining her 'Certificate in Further and Adult Education Teaching' she left the industry to develop customised executive learning programmes in the context of responsible business principles at the core of organisational development. She has developed ground-breaking 'Corporate Responsibility Leadership' programmes for directors and senior managers which are delivered in wilderness and mountainous places of natural beauty in Europe, Australia and China.

Sharon teaches business managers and directors how to combine fundamental business good practice and wealth creation with corporate responsibility as a core facet of global sustainability. Her programmes are designed to stimulate innovative and profitable business through aligning values based leadership with organisational sensemaking. She also undertakes long term consulting engagements to help businesses embed sustainability principles at the heart of their organisational development and strategy.

Her academic work includes the recent completion of a 2 year empirical study to explore the reasons for disconnect between organisational intentions to embed CSR and actual CSR outcomes. Sharon is continuing this research through a part time PhD at Cranfield University with a focus on 'The relationship between managers' sensemaking and organisational aspirations to embed sustainability principles'. Her research to date has revealed a unique contribution to theory and practice in terms of how individuals' sensemaking processes can be incongruent with organisationally espoused sustainability intentions and a barrier to enactment.
