About Marine

Seminars, conventions, conferences, company parties…

I help my clients design effective professional events by ensuring smooth and serene organization at every stage of the project.

My Added Value

My corporate background (Société Générale, Veolia, Caisse des Dépôts…) allows me to quickly understand the internal challenges, decision-making processes, and real constraints behind each project.

This positions me today as an event partner capable of creating truly useful events, whether for your teams or your clients.

My Working Method

I combine a strategic and operational approach with constant attention to client coherence, efficiency, and serenity.

What I Do

Depending on your needs, I can be involved in all or part of the project, from conception to on-site management:

✅ Scoping and consulting
✅ Venue research and selection
✅ Budget management
✅ Supplier coordination
✅ Logistics management (transport, accommodation, registration…)
✅ Event communication
✅ On-site management
✅ Post-event reporting and analysis

A company event is experienced on the day, but its success is built long before 😉

Let's discuss your next project!

See you soon,
Marine

I had the pleasure of collaborating with Marine twice on event project management assignments. Her professionalism and rigor far exceeded my expectations. Marine knows how to anticipate, organize, and coordinate perfectly, while maintaining excellent communication throughout the project. Each assignment was carried out brilliantly, on time, and with great quality of execution. I highly recommend her and will not hesitate to call on her again for future projects.
