MCO Congrès is the leading PCO in Southern Europe for the management of congresses/conferences in virtual/hybrid format or in person.

The MCO Congrès Group was founded by Marc Crousillat in 1990, joined by Dario Mougel in 1991.

Since its creation, MCO Congrès has specialized in the organization of events, conferences and scientific and medical congresses.

After 30 years we have become a leading PCO (Professional Conference Organizer) in France and Europe. We organize more than 50 conferences and events per year and have accumulated a tremendous experience with more than 1,500 events organized in France, Europe and worldwide.

This experience is based on 4 main axes:

  • Conference organization
  • Management of associations
  • Development of solutions for our digital events
  • Promotion and management of corporate and public events

This stability of our core business goes hand-in-hand with a financial stability that has enabled us to withstand the latest international financial crises and, more recently, the health crisis linked to COVID-19.

We have emerged from this crisis stronger and more united than ever. All jobs have been preserved and the team has remained intact. We have supported all of our clients and found fitting solutions for each of them.

After 5 years of rehabilitation, our headquarters office in the Villa Gaby has become the “Villa Medici for Medicine and Sciences in the Mediterranean area” that we were seeking to create.

A conference center that is unique in Europe and that offers a whole range of services to scientific communities: hosting of associations and learned societies, services and departments dedicated to the management of these associations, organization of face-to-face or digital meetings, office meetings, master-classes, campuses and summer universities, provision of high-tech teaching tools (videoconferencing, Web TV platforms, etc.)

Thus, when the world of event organization was interrupted in 2020, major congresses were able to take place digitally, from our Web TV platforms in the Villa Gaby in compliance with health recommendations, or entirely managed from our headquarters.

Coconstruction - Trust

Whether our clients consider us as a service provider or a partner, the success of the events we manage relies on the collaboration, communication and relationship of trust that we maintain with them, in order to co-build and carryout their projects.

We work as a team for greater responsiveness and flexibility!

Proactivity - Flexibility
Respect - Passion

We are a teamof passionate people who work together, exchange ideas on a daily basis, adapt to situations and hazards, and face challenges together, with benevolence, mutual aid, flexibility and optimism, in order to take advantage of experiences, promote and optimize each other’s good ideas and act effectively.

We aim at a very high level of requirement!

Professionnalism - Demand

We are concerned with doing things right, listening and paying attention to details, being proactive all the time and looking for quality, creativity, without ever being satisfied with the minimum, in order to try to be “the best” in what we do and always do better.

We seek to improve every day and cultivate transparency!

Transparency - Loyalty
Integrity - Improvment

We cultivate transparency with our clients and our service providers. Even if it is not always easy, there is no place for withholding information and it is important to us to share information in order to improve: question ourselves, accept that we can do better, learn frompast experiences, transmit our expertise…

Accessibility for People with Disabilities

Depending on the individual's situation, adaptation and compensation measures can be implemented to ensure participation in the conferences. All the venues hosting us are wheelchair accessible.

Curiosity is a quality!

Creativity - Involvement - Winning spirit

We are always on the lookout for new ideas and we are always willing to learn and adapt them to our business. We are interested in our clients, their fields of activity and their specialties. We question the relevance of the ideas and actions implemented. We seek to understand the expectations of our clients, partners and delegates. Finally, we share our findings and expertise.
