There have been a raft of top-level changes at the UK-based wealth management house.

Guy Monson, who has been a prominent figure in London's investment community for more than a decade, has handed over his duties as managing partner at Sarasin & Partners to Greg Matthews to focus on his chief investment officer role. He becomes senior partner, the firm said yesterday.

Matthews will lead the business and chair the firm's executive committee. Matthews joined Sarasin & Partners in 1994 after a career at Smith & Williamson as a chartered accountant. He has been chief operating officer of Sarasin & Partners since 2010, previously serving as the chief financial officer of the Sarasin (UK) Group since 2002. He was formerly chairman of the Financial Services Authority’s Smaller Businesses Practitioner Panel and a member of the FSA’s Practitioner Panel.

Head of operations Tim Temple will succeed Matthews as chief operating officer. Temple joined the firm in 2005 and became head of operations in 2009. Prior to this, he worked at WM Company, Deutsche Asset Management, and The Bank of New York.

Separately, Sarasin also appointed six new partners: Chris Bell (legal counsel), Edward Campbell-Johnson (private clients), Phil Collins (asset management), Ruadhri Duncan (charities), Melanie Roberts (charities), and Tim Temple (operations).

Sarasin & Partners manages £13.6 billion of AuM (as of 30 June 2016).
