Accounting Today's Top 100 Firms List Ranks RSM No. 5

CHICAGO – (March 22, 2021) – RSM US LLP (RSM) – the nation's leading provider of audit, tax and consulting services focused on the middle market – was recently ranked as the fifth largest accounting, tax and consulting firm in the U.S. for the tenth consecutive year by Accounting Today.

The publication’s special report indicates that overall growth for the Top 100 Firms was 9.32 percent, up a percentage point from the roughly 8 percent figure for the four years prior. Much of this year’s growth was driven by merger activity, and RSM was no exception. RSM M&A activities highlighted in Accounting Today’s special report include:

  • May 2015 – joined forces with Alabama-based Sellers, Richardson, Holman & West
  • August 2015 – joined forces with PKF San Francisco and St. Louis-based Wolfe Nilges Nahorski
  • December 2015 – joined forces with Dynamics AX provider Junction Solutions.

Another RSM highlight mentioned by Accounting Today: the firm (formerly McGladrey) rebranded as RSM US LLP in October 2015, uniting fellow firms from more than 120 countries in the RSM International network under a common brand. In conjunction with the brand launch, the firm issued the first global edition of The Real Economy, a monthly publication that helps middle market business leaders anticipate and address the unique issues and challenges facing their businesses and the industries in which they operate.

“This year, we are celebrating our firm’s 90th anniversary of serving middle market leaders across the nation and around the world,” said Joe Adams, managing partner and CEO for RSM US LLP. “It’s nice to celebrate our 10th consecutive No. 5 Accounting Today ranking in conjunction with this significant milestone in RSM’s history. Our founder, Ira B. McGladrey, would be proud of how we’ve grown our scale and capabilities to serve the middle market while remaining true to his founding priciples: provide outstanding client service, treat employees well and do your work honestly and ethically.”

"2020 was an unprecedented year – for our industry, our firm, our clients and our people,” said Joe Adams, managing partner and CEO with RSM US LLP. “Our people rose to the challenge, pivoting quickly to working remotely while providing our clients with the same high-quality service we provided before the pandemic. Thanks to our people’s commitment and innovation, and to our clients’ loyalty, we were resilient in the face of 2020’s challenges, and we’re looking forward to continuing to work with clients to reimagine the future in 2021 and beyond."
