Our associates





While Greg Lee is the principal consultant, we regularly put together a team of professionals to suit a client's requirements.

Meet some of our associates:

     Maureen Moss

Maureen is recognised by her peers and her clients as one of Australia’s leading practitioners and coaches of communications and leadership skills — all based on frameworks and techniques for dealing with people. Whether in sales, customer service or management, people need to communicate effectively, persuasively and constructively and this is where Maureen can make a difference.

After beginning her career as a teacher, subsequent years in roles as salesperson, trainer, and manager with Telstra, Mercuri International, and others, Maureen reached the level of Managing Director of Bid Pty Ltd, a mid-sized training and consulting company that worked predominantly in the finance and media industries. At Bid, Maureen introduced a ’key client’ management strategy that assisted in the growth of the business to double within the first 12 months.

Maureen has been training and consulting for almost fifteen years now, at various levels within organisations as diverse as NRMA, CSR, Knight Frank, AGL, Kyocera, CBA, Westpac, Merrill Lynch and Rabobank, in Australia, New Zealand, and the UK. She has worked with elite sportspeople such as the Australian cricket team and Sydney Olympians, and coached up to MD and CEO levels via the Australian Institute of Company Directors and her own business.

Clients from all levels regularly make comments such as “no-one else has Maureen’s ability to demonstrate and coach our desired behaviours” and “Maureen has the maturity to ask us probing questions, plus the experience to answer our own challenging questions of her”.

Her pre-eminence in her chosen fields is further evidenced in her popularity as a coach and source of train-the-trainer for others in the management consulting industry.

David has developed and delivered many training workshops for several large clients covering all aspects of procurement, negotiation, relationship management, contract set up and management - and brings a ’reality check’ based on many years of actually implementing the concepts and delivering benefit. David’s style is very ’inclusive’, personable and engaging - using personal experiences and humour to bring to life practical concepts.

While many of the workshops delivered are ’tailored’ to suit individual clients a range of ’standard’ procurement workshops are available. All of the workshops focus on an interactive style encouraging attendees to participate, trying out new concepts through case studies and role play.

David’s focus has always been on the practical implementation of change as a business concept as well as from a procurement perspective. He believes that delivering to the bottom line in a real and continuous manner is what drives home the philosophical concepts.
