History

RSM was founded in 1926 by Ira B. McGladrey (1883-1952) in Cedar Rapids, Iowa.

McGladrey became a prominent figure in public accounting in Iowa, serving as President of the Iowa Society of Certified Public Accountants, chairman of the Iowa Board of Accountancy, as well as a member of the Rules Committee of the American Institute of Certified Public Accountants, the premier governing body for the field of accounting in the United States.[4] The firm continued to operate under some variant of the McGladrey name for nearly nine decades, until 2015 when the firm was rebranded as RSM US LLP to alighn with its global network.

Beginning in 1999, through a partnership with H&R Block, McGladrey operated under two separate legal entities: McGladrey & Pullen, LLP; and RSM McGladrey, Inc. McGladrey & Pullen operated under the traditional partnership structure and offered audit and attestation services. RSM McGladrey was established under the partnership agreement with H&R Block to provide tax and advisory services under an alternative practice structure.[5][6]

In August 2011, H&R Block announced the conclusion of the partnership, divesting RSM McGladrey to McGladrey & Pullen and reuniting the firms in their traditional partnership structure. McGladrey & Pullen acquired all employees, assets, and infrastructure from RSM McGladrey.[7] The deal closed on December 1, 2011.[8]

On May 1, 2012, McGladrey & Pullen officially changed its name to McGladrey LLP. In July 2012, McGladrey shifted its headquarters from Bloomington, Minnesota to Chicago.

On October 26, 2015, McGladrey LLP changed its name to RSM US LLP as part of a worldwide rebranding of RSM International members to create a unified global brand.[9]

On January 1, 2026, RSM US LLP joined with RSM Firms in the UK, Canada and Ireland to form a transatlantic partnership designed to improve cross-border services for international clients. The participating firms remained separate legal entities under a centralized governance structure.[10] On June 15, 2026, the firm announced that Mexico would also join the partnership.[11]

RSM US LLP is a limited liability partnership. It is an independent member of the RSM International network.[10]
