The story

RSM International was founded in 1964 as a small network called DRM (Dunwoody, Robson Rhodes, and McGladrey & Pullen). The organisation restructured in 1993, changing its name to RSM International. The word International was dropped in 2015.

Historically, RSM was derived from the initials of three of the original founding member firms of the organization:

Robson Rhodes (United Kingdom)

Salustro Reydel (France)

McGladrey (United States)

Founding member Robson Rhodes was acquired by Grant Thornton and absorbed within its network, while Salustro Reydel merged with KPMG. McGladrey, the member firm of RSM US, is still part of the network today.

In January 2006, Jean Stephens became the first female chief executive officer of an international accounting network in the Top 10.

In April 2024, it was announced that Ernest John Nedder would become CEO on 1 June 2024
