RSM International is a privately owned entity headquartered in the United Kingdom. Founded in 1964 as DRM and later restructuring as RSM International in 1993, the global organization functions as a multi-national network of independent audit, tax, and consulting firms. It serves corporate clients, with a primary strategic focus on middle-market businesses. The network is managed by RSM International Limited, a legal entity responsible for administrative coordination and brand governance, rather than for the direct practice of professional services.
