What Our Clients Are Saying

Dawn Graham, Sales Coach

"Brett's vast knowledge of the "new" body language, micro-emotions, psychology and human behaviour was really obvious. His enthusiasm, great delivery style, and professionalism made an already interesting subject area totally fascinating."



Tracy Kearns, CIPD

" I made £50,000 within 3 days after finishing Brett's course, by being able to recognise what wasn't said. Fascinating, easy to use, but most of all, a must-have if you want to ethically influence others and learn how to decode people." 

Dawn Graham Sales Coach

Working with Brett and interpersonal insights has added real value to our law firm, not only have they helped as consultants with court preparation, they continue to teach practical and easy to apply communication strategies to all of our new staff and senior partners.

Law Firm, New York, USA


Brett is exceptional at what he does and it was immediately obvious that the years he has spent on his own development has made him highly skilled in what he does. 

I commissioned Brett on a one to one basis to further enhance my communication skills and to help with my reading of a clients body language. The depth that he goes into is amazing, I especially love the reading of Micro Expressions - for any fan of the Tim Roth series "Lie To Me".

It has been a pleasure to introduce Brett to some major Corporate companies including The University of Birmingham and Natwest/RBS where he has worked his magic to improve teamwork, morale and above all results.

If you have a chance to work with Brett then I cannot recommend him highly enough.
