RSM International announced a global rebrand in October 2015, with its more than 110 member firms adopting the name worldwide.
Prior to the rebrand, RSM UK was known as Baker Tilly. The firm officially joined the RSM International network in 2014, after it purchased RSM Tenon out of administration in 2013. The merger saw the firm’s workforce increase to 3,500 employees, as well as creating a joint fee income of more than £300m.
Laurence Longe, RSM’s CEO said the results “very clearly show the commercial benefit of the major investment that has been made in first reshaping and then rebranding the firm following the absorption of the former Tenon business.”
In September, the firm added 288 new trainees to its roster, to work across 30 of its UK offices. The new intake took the total number of employees to over 3,600.
