About Nathalie

For many years, I have been supporting companies, associations, and leaders in the administrative, financial, and organizational management of their activities. My goal: to make operations smoother, more reliable, and to allow teams to focus on their development.

I started in administrative, commercial, and accounting roles where I learned rigor, priority management, and a service-oriented approach. Very quickly, I moved into more strategic positions combining coordination, financial management, event planning, and executive support.

One of my most significant experiences was participating in the development of the national Advenir program dedicated to electric mobility. There, I supported the management of a fund from €12 to €500 million, ensuring budget monitoring, stakeholder coordination, and the structuring of management tools in a demanding and fast-growing environment. Launched in September 2016, the program was renewed until 2030.

Accustomed to demanding contexts, I now act as a true operational right-hand person. Administrative and financial management, HR monitoring, reporting, event organization, multi-stakeholder coordination, or process optimization, I provide concrete and quickly actionable solutions.

This approach has notably allowed me to improve recovery by 20% in a few months and to stabilize monthly closings at D+5 over a full year.

As a freelance Office Manager, I primarily support VSEs, associations, and developing structures that are looking for reliable, autonomous, and structuring support.

My goal is simple: save time, bring peace of mind, and enable teams to work in a clearer, more efficient, and better-managed environment.
