Irwin Mitchell has grown its commercial litigation team with a trio of partner hires from Eversheds, DLA Piper and Matthew Arnold Baldwin.

Eversheds' Jonathon Crook, Matthew Arnold Baldwin's Jonathan Sachs and DLA's Dorrien Peters move to Irwin Mitchell's Manchester, London and Sheffield offices respectively.

The new partners will all join the firm's business legal services division, bringing the number of partner hires in the division to seven so far this year.

The appointments follow the recruitment of Pinsent Masons disputes head Nigel Kissack, who joined Irwin Mitchell as its national head of commercial litigation at the end of 2013.

Sachs, a professional negligence lawyer who previously led the disputes teams of Pettman Smith and Sprecher Grier Halberstam, joined Matthew Arnold in 2010 as the head of its professional indemnity team, and has international experience across Europe, the Middle East, USA and Africa.

Crook – previously a partner at Simmons & Simmons and Clifford Chance in Hong Kong – has helped to build Eversheds' commercial litigation team in Manchester since his return to the UK in 2001, with a practice focus on financial services dispute resolution and contentious regulatory matters.

Originally qualifying as an electronic engineer with BAE, Peters specialises in complex disputes in the IT, manufacturing, engineering and construction sectors.

"Irwin Mitchell has added significantly to the breadth and depth of its commercial litigation offering in the last 12 months," commented Kissack.

"We have added considerable IP and contentious tax expertise recently and these latest hires add strength in a number areas including finance litigation, corporate disputes and professional negligence."
