Gary Oakley

“Most of the highly effective negotiation skills are counter-intuitive; fortunately they can easily be learned”

Gary is an international influencing and negotiation strategy consultant and trainer who has been an expert with INS Limited and our international partners ENSI since 1989. He brings neuroscience insights into his strategies where small changes in preparation and behaviour can generate big changes in results. Gary has worked on negotiations throughout every continent (except Antarctica).

He comes to the influencing and negotiation arena from a professional background in property finance. He now works across many industries (including service, pharmaceutical and manufacturing) and of varying sizes of organisations and government ministries.

Melanie 1_resize.jpg

Negotiation Strategist and Coach

Melanie Lilley

The first negotiation is with oneself

For over twenty years Melanie has focused on understanding and developing others in her training role in L&D and now as an OCM qualified coach and team coach. Using psychology and neuroscience, she aims to unlock potential through careful conversations and building relationships. Never underestimating the power of communication – verbal and non- verbal for successful engagement.

Given that organisational results depend on the behaviours of people, and that behaviour is governed by how our brain reacts to stimuli around us, it’s clear that if we understand why our brains behave the way they do our negotiation skills have a greater chance of succeeding.

Having worked in both the public and private sector (both large and small), Melanie is familiar with the unique nature of each and the driving underlying behaviours.  Global training contracts have also given a greater cultural understanding – both for business and pleasure.

Melanie enjoys travel when possible and is constantly amazed by human nature in some of the most remote and underprivileged corners of the world – a little courtesy and the right questions can open some amazing doors and build the first key step – trust.

Neuroscience provides a lens through which we can better understand ourselves and others'

Ellen is one of our Neuroscience researchers; to understand the chemical side of behaviour. She is currently focusing her research on the expanding generation gap, as well as how genders and cultures differ in communication and negotiation styles.

Ellen studied Psychology and Sociology at University to develop her interest in human behaviour and what motivates us. Her background in mental health care and working with autistic children has shown her just how important communication is and why we need to understand people in order to communicate and negotiate effectively.
