RSM International review

RSM International was founded in 1964 as a small network of tax and consulting firms and was originally called DRM. In 1993, the company was reorganized and its name was changed to RSM-the initials of the heads of the three original founding firms of the organization: 

  • Robson Rhodes (United Kingdom)
  • Salustro Reydel (France)
  • McGladrey (USA)

Now RSM International has grown to the world's sixth international network and is a provider of audit, tax and consulting services for organizations. It has offices in 120 countries and 43 thousand employees in more than 800 offices. The member firms of the RSM International network are independent audit and consulting firms, each practicing on its own but unified as part of the network. The entire RSM network is managed by RSM International Limited, a company registered in England and Wales.
