Who we are
RSM is a leading international network of audit, tax and consulting firms, present in the main economic centres around the world.
In Switzerland, our teams work closely with clients to understand their business, anticipate change and support informed decision‑making in an increasingly complex environment.
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 Switzerland
RSM Switzerland was built through the creation, integration and development of several established firms across Switzerland’s main economic regions.
Over the years, these firms progressively came together under the RSM brand, combining strong local expertise with international standards, methodologies and resources.
This development has enabled RSM Switzerland to grow into a national organisation while remaining close to its clients, its people and its regional markets.
Today, RSM Switzerland supports companies, entrepreneurs and private clients with audit, tax, accounting and advisory services, combining in‑depth knowledge of the Swiss environment with access to the global RSM network.
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.
Thanks to this global reach, RSM’s expert teams are equipped to support clients at every stage of their development, both in Switzerland and internationally.
