About Claire

I support organizations facing challenges in transformation, repositioning, or modernization of their communication.

For over 15 years, I have worked with public institutions and high-stakes organizations (City of Paris, National Management Center, parliamentary office), where I have led global communication strategies, supported strategic roadmaps, and structured engaging internal and external initiatives.

My expertise covers both the definition of orientations and their operational deployment: clarifying positioning, formalizing key messages, redesigning digital systems, mobilizing teams, and change management.

Accustomed to complex and sensitive environments, I know how to coordinate multiple stakeholders, secure messages, and transform a strategic vision into a concrete action plan.

I undertake missions in communication strategy, institutional communication, change management, and structuring internal initiatives.

Experience

  • Association Un doux moment pour soi
    Conception and management of a high-impact associative project (strategy & deployment)
    January 2024 - Today (2 years and 5 months)
    Paris, France
    In parallel with my institutional communication roles, I conceived and launched an innovative associative project dedicated to mental health.

    I managed the entire process, from opportunity analysis to operational structuring: definition of positioning, brand strategy development, editorial line construction, development of an engaged community, activation of partnerships, fundraising, and design of a hybrid business model.

    This project led me to mobilize transversal skills in strategy, project management, stakeholder coordination, impact communication, and ecosystem development.

    It illustrates my ability to conceive a vision, structure it, embody it, and deploy it in a constrained environment.
