Meeting with Cécilia Sonnet

A former manager and sales director in the digital world, Cécilia Sonnet spent ten years at Webedia leading high-stakes teams and projects in France and then Spain. A trainer since 2021, she now puts her field experience to work for the managers she coaches. Using an approach that combines Nonviolent Communication and body awareness, Cécilia helps managers gain clarity, accuracy, and interpersonal skills so they can perform their roles with greater confidence and impact.

Can you tell us more about your background?

From 2010 to 2020, I worked at Webedia, a digital agency specializing in content creation. I initially held the position of Client Director in France (2014–2017), where I was responsible for developing the commercial side of the business, growing it from 200 to 1,500 employees and expanding its presence to 10 countries. I then took over the management of a Business Unit in Spain (2017–2020), where I led a team of seven people, with a role combining management and business development, in a context of hypergrowth. Now a trainer and facilitator since 2021, I help managers clarify their position, build quality professional relationships, and embody managerial excellence.

What are your areas of expertise?

I focus primarily on managerial responsibility and the manager's attitude, with a clear objective: to strengthen team commitment and loyalty. I address highly operational topics such as motivational levers, assertive communication, Nonviolent Communication (NVC), conflict prevention and management, intergenerational management, and the art of giving and receiving feedback. 

I mainly work with local managers, members of the executive committee, and their teams. I am often asked for advice on very specific topics: managing time and energy, getting teams on board, setting professional/personal boundaries, supporting change, and getting messages across that are heard and create momentum.

How and why did you decide to collaborate with NUMA?

I like the very practical and realistic approach of the training courses offered by NUMA. The reality of a manager's daily life is, by definition, complex and constantly changing. Here, there is no moralizing tone, complex theories, or clichéd advice. Each workshop is designed to make managers' lives easier with concrete tips and actionable tools that have been tested and approved! These are the training courses I would have loved to have had as a manager! 

How do you integrate your professional experience to engage participants?

For each workshop, I like to look back on my life as a manager, when I had little management training and few opportunities to take a step back and reflect on my approach and practices.

I remember my challenges, the reality of my daily life, but also the emotions I went through, the satisfying moments and the moments when I doubted my ability to be a good manager. It's a valuable resource that I use to introduce workshops and encourage participants to speak freely.  The adage "you're not born a manager" takes on its full meaning. It's reassuring, you feel less alone with your questions, and in the end, it's these moments that are valuable for creating sharing and learning exchanges between participants.

What's the key to successful training?

As a coach, I really feel like a partner when I lead workshops. I enjoy working with managers on their challenges, starting with their current practices and helping them take one step, then two, toward their goal.
I feel completely satisfied when I sense that everyone leaves with a new insight, a tool, or a different way of approaching their role as a manager. And with a smile! 

Can you share with us some techniques or methods that you regularly use in your training sessions?

My approach is primarily focused on the needs of participants, which involves a lot of groundwork: I take the time to gather and analyze requirements, a reflex that comes directly from my experience as Client Director at Webedia. This allows me to develop tailor-made support programs that are truly adapted to the context.

I also approach managerial responsibility from the perspective of NVC, a lens that encourages us to reexamine our relationship with ourselves and others. This often requires changing our habits, beliefs, and behaviors, with a genuine sense of exemplarity.

Finally, I like to mix training and coaching: combining teaching time, individual development, and moments of collective intelligence. I can also introduce exercises to reconnect with the body and emotions, drawing on my experience as a certified yoga teacher (around forty students per week).
