Sophie Plaquet - Power4

The founder Sophie Plaquet runs Power4 Coaching.

Following a Master’s Degree in Commercial and Financial Sciences, which led to more than 15 years corporate experience, I am now a Coach Consultant in Human Management, certified “Coach & Team+” by Vincent Lenhardt.

As a specialist in transactional analysis and a “certified coach and trainer” in Process Communication Management, I have also trained in the study of organizational structures (TOB) and in the Palo Alto school’s systemic and strategic analysis. I’m also specialized in NeuroCognitive and Behavioural Approach.

Why turn to corporate coaching?
In the managerial posts I occupied, I was face-to-face with all the tensions inherent to the life of dynamic companies adapted to their strongly competitive environment. It took me several years of stress and various tensions to realise the crucial importance of our human resources and their driving force in companies: man is considered above all as a “subject of growth” and not just an “object of production”. The many training courses I attended following this awareness further confirmed this opinion and gave me the desire to combine my understanding of corporate stakes with the complexity of human management.
