Antonia Dodge is an author, thought leader, coach, trainer, systems thinker, and personality profiling expert. At the age of 15 Antonia picked up a book on personality psychology and her world changed forever. She began to see the patterns of why people do what they do - not based on behavior alone - but based on how the mind works. Antonia has co-developed a 6-month profiler training course that teaches coaches and business professionals how to speed read people, understand how their mind works and and then work with the unique personality for achievement, life purpose, or team building.
