Irwin Mitchell was founded by Walter Irwin Mitchell in Sheffield in 1912 as a general practice firm. His aim when he founded the company was to provide the highest quality law services to the general public.
The company remained solely in Sheffield until its first expansion into a Birmingham office in 1989, the Leeds arm was next to follow, opening its doors in 1993. The company continued to acquire companies throughout the 1990s, with Sheffield outfit Kershaw Tudor in 1994; Leeds-based corporate and commercial firm Teeman Levine in 1995; and Birmingham corporate specialist Rigbeys in 1996. A City branch was launched in 1995 and added to another series of merger deals - with debt recovery and insolvency firm Braby & Waller in 1998 and personal injury outfit Lorenzo Zurbrugg in 2003. The firm launched in Newcastle in 2003 then opened its sixth office in Manchester in 2006. The company’s expansion went further afield in 2005 with the opening of their offices in Marbella (which then moved to Malaga) and Madrid. The year Irwin Mitchell moved internationally was also the year the firm’s annual turnover broke the £100m barrier.
