Clients around the world turn to Grant Thornton for its asset recovery, digital forensics and forensic accounting services.

The firm

Having already established itself as a leading forensic accounting firm with stronghold practices in the US and the UK, Grant Thornton continues to expand its reach around the globe. It has established investigations practices in India, the Netherlands and Germany. 

Grant Thornton was founded in Chicago as Alexander Grant & Co in 1924, and by 1980 it had joined with 49 other accounting firms, including Thornton Baker in the UK. The firm maintains a major US presence with approximately 150 dedicated forensic professionals, most of whom are in New York, Chicago and Washington, DC.

The US practice is led by global co-leader Erik Lioy who focuses on financial fraud investigations including corruption and kickback schemes, healthcare billing fraud, and construction and real estate fraud. Meanwhile, Paul Peterson returned to the US after a three-year stint in China, where he launched the firm’s China forensic practice.

Grant Thornton UK launched its investigations practice in the 1980s. It’s now led by global co-leader Will Davies in London who is an experienced forensic accountant with a specialty in advising financial services and private equity funds. He is often retained by regulators in Europe and the Caribbean and has worked on many investigations into fraud and insider trading.

Alongside Davies is Kevin Shergold, who heads the investigations practice and handles a range of matters including UK Bribery Act and FCPA investigations, and asset tracing. Kevin Hellard leads the insolvency offering in the UK and globally, and has been named as Asset Recovery Expert of the Year for 2018 by Who’s Who Legal.

Vijay Rathour leads the digital forensic practice in the UK, which focuses on assisting clients with e-discovery and data analytics, and responding to cyberattacks and data breaches.

Grant Thornton established its Ireland forensic practice in 2004. This has grown with the help of partner Paul Jacobs, who recently represented the Olympic Council of Ireland in response to an investigation into the illegal resale of Brazilian Olympics ticket allocated to the Irish sports body. Jacobs was formerly a director at EY, where he had worked since 1992.

In the Netherlands, the firm began its investigations work in 2010 by acquiring a Dutch forensic boutique firm. The team has a mix of accountants, lawyers, former government officials and digital forensic specialists who have acted as court appointed expert witnesses. It has also undertaken bribery and corruption investigations in China, Poland, Moldova and Russia.

In Canada, the practice is led by Jennifer Fiddian-Green, an anti-money laundering specialist who has handled more than 250 investigations across multiple industries. She previously served as a diplomat at the United Nations focusing on economic relations between the US and China.

In 2000, the German firm Warth & Klein joined Grant Thornton to create Warth & Klein Grant Thornton. The firm expanded its investigations work to Germany in 2014, and focuses on the financial services, automotive, and manufacturing sectors.

The firm has also built forensic practices across China, with a main office in Shanghai which houses a digital forensic laboratory for data to be processed and reviewed. Tim Klatte leads the forensic practice in China.

Additionally, Grant Thornton was one of the first accountancy firms in India to start a forensics practice, and gained traction when Vidya Rajarao joined the office in 2014 from PricewaterhouseCoopers. Rajarao leads the practice in Bangalore, with over two decades of experience in forensic accounting in India and the US. Grant Thornton India has more than 70 forensic professionals, and has conducted investigations and asset tracing for the State Bank of India, IDBI Bank and Axis Bank.
