Accountancy and advisory firm Simmons Gainsford has acquired Riordan O’Sullivan and Co, a North-West London practice established in 1968.
The acquisition, part of Simmons Gainsford’s growth strategy under the Sumer Group, will see Riordan O’Sullivan and Co rebranded under the Simmons Gainsford name. The practice will continue operating from its existing offices in Kensal Rise.
Founded by John Riordan, the firm has built a longstanding client base, offering accounting and advisory services across the local business community. The team of three partners – James Riordan, Paddy McNamara and Kumar Perumal – along with 16 staff, will join the wider Sumer Group, which now comprises over 2,500 employees across more than 50 offices nationwide.
Darren Hersey, senior partner at Simmons Gainsford, said: “We are delighted to welcome Riordan O’Sullivan and Co to our group. Their excellent reputation and strong client relationships perfectly complement our mission to champion SMEs throughout the UK.”
Kumar Perumal, partner at Riordan O’Sullivan and Co, added: “Joining Simmons Gainsford marks an exciting new chapter for our firm. Our clients will benefit from enhanced service capabilities while maintaining the hands-on personal relationships we know they expect and value.”
Simmons Gainsford was advised by Dickson Minto, while Burlingtons acted for Riordan O’Sullivan and Co.
