National accountant and advisory business RSM Tenon has appointed Chris Merry as chief executive officer with immediate effect.
Merry's most recent role, between 2007 and 2011, was as CEO of Matrix Group, a privately owned financial services business in the UK.
Prior to this, from 2004 to 2006 he was finance director and then CEO of Whitehead Mann, an executive search group listed on the London Stock Exchange.
Former CEO Andy Raynor stepped down as chief executive last month, while Bob Morton has left his role as chairman.
Concerns were raised in January about the role of auditors PricewaterhouseCoopers (PwC) after financial uncertainties arose at RSM Tenon.
According to unverified reports, PwC gave Tenon a clean bill of health just months before a suspected "black hole" appeared in its finances.
