Sue Nightingale joins Quantuma as director in forensics team

Business advisory firm Quantuma has appointed, Sue Nightingale, as a director. The forensic accounting expert will be a key member of Quantuma’s growing disputes, investigations and valuations practice.

On her appointment, Nightingale commented, “I am delighted to be joining Quantuma and to be working within the firm’s dynamic disputes, Investigations & Valuations team. Quantuma has ambitious growth plans which are reflected in a commitment to increase our capabilities in the South East region. I am looking forward to supporting these ambitions and playing a key role in growing the team.”

Nightingale was most recently with BDO, where she was a director in the firm’s forensic accounting and valuations team, specialising in expert and other dispute advisory business valuations.

Prior to that, she began her career spending 11 years with Deloitte’s forensic team working across a broad range of disputes and investigations, including high profile UK and international investigations and quantifying losses in the context of complex, high-value commercial litigation. She has also since spent time with Roffe Swayne Accountants, Tax & Business Advisers, Stowe Family Law, and FRP Advisory.

An experienced expert witness and other dispute advisory work in the context of commercial litigation, divorce, expert determination and insolvency proceedings, Nightingale will continue to act on behalf of claimants and defendants and has worked with high-net-worth individuals, family offices, partnerships and companies, including early stage and/or fast-growing private equity backed businesses with complex debt and capital structures. She will be predominantly based in Quantuma’s Guildford office, working for clients across the London and South East region.

The move adds further depth to Quantuma’s growing disputes, investigations and valuations team and follows the appointment of Hannah Griffin, who joined the firm as a managing director in the firm’s Birmingham office earlier this year.

Quantuma managing director and head of Disputes, Investigations and Valuations, Gavin Pearson noted, “I am very pleased to welcome Sue to our team as we continue to grow our market presence, particularly in London and the South East. It is great to see Sue re-joining Kate Hart and other members of the Guildford team who she has worked with previously.”
