About RSM US LLP

RSM US LLP is an audit, tax and consulting firm focused on middle-market businesses. It describes itself as the U.S. member firm of RSM International, a network of independent assurance, tax and consulting firms. The firm traces its roots to 1926, when Ira B. McGladrey founded an accounting practice in Cedar Rapids, Iowa, and it adopted the RSM US name in 2015. It is a licensed CPA firm, and its website lists assurance, business tax advisory, risk consulting, transaction advisory and management consulting among its service lines. Its published descriptions center on accounting, audit, tax and consulting work rather than legal practice.

Third-party directory listings describe its services as including family office services, mergers and acquisitions, and risk, fraud and cybersecurity work. The firm reports more than 80 offices across the United States, along with teams in other countries through the RSM International network. In New York State, its listed office is at 151 West 42nd Street in Manhattan, and the firm's New York page gives 212.372.1000 as the contact number.
