Mark Tantam Appointed as Head of Forensic Services of Teneo’s Financial Advisory Business

Teneo, the global CEO advisory firm, today announced the appointment of Mark Tantam as Head of Forensic Services in its Financial Advisory business.

In this role, Mark will build on Teneo’s existing capabilities to create a global forensic team with the skills and experience to help clients successfully resolve complex regulatory and contentious issues.

Mark Tantam is a criminal lawyer, former prosecutor and forensic investigations expert. He spent nearly 30 years in the Forensic Department of Deloitte UK, rising to become head of that Department and Vice Chair of the firm.

Mark Tantam commented: “Throughout my career, I have helped Boards manage the most serious regulatory and criminal risks. The provision of independent advice is critical, and I am therefore very excited about the opportunity to assemble a global forensic team within Teneo. We will build on Teneo’s existing track record of guiding companies, regulators and other stakeholders through complex issues and helping them to create certainty from uncertainty. In doing so, I will draw on forensic professionals with a proven track record in investigations, disputes and forensic accountancy and leverage cutting-edge technology in the areas of analytics and document management.

“We are delighted to welcome Mark to Teneo as part of our ongoing global growth strategy,” said Daniel Butters, CEO of Teneo’s Financial Advisory business. “Mark’s arrival is a key step in our expansion in the forensic services arena. He brings a wealth of experience and relationships to build on our existing capability and drive a step change for Teneo in this area.”
