Any change is a unique and exciting journey

That’s why success depends not on tools, technologies or methodology… but on the men and women who embark on this journey?

This conviction leads us to offer you personalized support in 2 areas

My vision

Performance is, above all, the one of women and men, individually and collectively

For over 25 years, I have been coaching management teams and talent in France and abroad, to create effective, learning organizations that enable everyone to develop and flourish. I am convinced that individuals and team spirit are the key to a successful strategy. It is essential to place them at the center of the organization, with an operating model based on commitment, responsibility, listening and benevolence. I like challenges, I look to topics with a different angle, an angle that questions, awakens, and creates opportunities.

Facing transformations, it’s important to define the vision, the meaning of the change, and to support teams in carrying out the project.

Surrounding yourself with a consultant in Organization, Human Resources Strategy and Change Management is key at these important moments. At the same time, support for teams and leaders is essential, as it is they are the ones who must be able to carry the project through its deployment phase and beyond, to make it a lasting success.

“Consulting” and “Coaching” are the 2 essential ingredients of a successful transformation.

From vision to action

Connecting the dimensions of vision and action with the ones of listening and support.
Our approach is therefore focused on the specific challenges of the client, looking at the systemic aspects related to the project, whether it is a request for advice in Organizations and Human Resources or a request for coaching. The work is done on the 3 essential drivers of sustainable success, namely the Head, the Heart, and the Body.
Our approach is therefore based on 4 dimensions and 3 drivers

The dimension
of the organisation

The systemic

The dimension
of the Business

The systemic

The dimension
of the individual

Authenticity and

The dimension
of relationships

The importance
of the alliance

Co-creation with the client and strong values

A logic of co-creation focused on each client’s specific needs.

It is about creating a true partnership/alliance with the client and relevant stakeholders to create a clear contract covering the consultancy mission, the process, the challenges and the objectives.

BroadenUp's values


Listening is an essential part of my approach. It starts with the first contact with the client to understand their needs. In coaching, it involves establishing silence and availability, so that the coach is totally connected to his client, hears his needs and feels the situation. Listening is also about being present to oneself, which allows one to be fully engaged in the relationship with the other. Listening is done in 3 dimensions: listening to the mental path, listening to the content, listening to the non-verbal


Trust is also a key factor in customer relations. I pay particular attention to this because it determines the quality of the assignment from start to finish. It allows us to get to the bottom of the issues while respecting all the stakeholders. I like David Maister's equation in his book "The Trusted Advisor", where he writes that trust is based on Credibility (experience), Reliability (seriousness of approach) and Intimacy (being totally connected to your customer), all focused on the customer's needs.


For me, responsibility means being accountable for one's actions, having the ability to fulfill one's obligations. As a consultant and coach, I respect my ethical, contractual and legal obligations towards my clients.

Value creation

BroadenUp's raison d'être is to be a "Performance Booster" and to accompany transformations, for the company, the teams and the individual. Value creation is an essential dimension of my approach. It must enable the client to develop its economic performance, through work on vision, team mobilisation, the development of behaviour and relational skills, self-awareness, and motivation and commitment. It is by liberating individual and collective energies that the company will find its full potential and create value in the long term.


Finally, courage is an essential value in my approach. As a consultant and coach with many years of professional experience, I've seen how courage can take on the most ambitious challenges. It's essential to encourage customers to tackle difficult issues and find ways to achieve their goals.
