L'histoire de RSM est celle d'une ambition collective: devenir un acteur majeur du secteur de l'audit, de l'expertise-comptable et du conseil. 

RSM International

RSM's story began in 1964 when the foundations of the network were laid, providing accounting services to industrial and commercial enterprises. Over nearly three decades, the network expanded by integrating numerous firms from different countries around the world.

In 1993, the network officially adopted the name RSM International, an acronym derived from its three founding firms: Robson in the United Kingdom, Salustro in France, and McGladrey in the United States.

From that moment on, RSM International positioned itself as the world's 6th largest audit, accounting, and advisory network within the Next 4 global firms.

In 2015, all member firms and offices worldwide unified under the single RSM brand, symbolizing the consistency and coherence of our service offerings across the globe.

RSM France

In 2004, Salustro Reydel exited the network. However, its partners—particularly in Lyon, Nantes, Colmar, and Paris—continued their collaboration and formed RSM France.

In 2013, the firms MBV and Corevise merged to create RSM Paris, joining the RSM network in France.

Between 2013 and 2015, RSM expanded its footprint across key economic hubs, integrating firms based in Laval, Colmar, and Montpellier. These historic firms later established a subsidiary in the French Overseas Territories (Réunion and Mayotte), as well as a Shared Services Center (CSC) in Mauritius.

Since then, RSM has continued its growth, strengthening its presence across various regions. Since 2015, offices in Grenoble, Rennes, Aix-en-Provence, Albertville, and Strasbourg have joined the RSM journey.

RSM International is the 6th largest global network in audit, accounting, and consulting. It operates in over 120 countries, with a workforce of more than 65,000 professionals worldwide.
