Mark Plato - Former CEO

Mark Plato, who served as Telent’s CEO from its formation in January 2006, was integral to the creation of Telent and led the company to great success.

Establishing Telent as an organisation with strong and capable management teams in each business unit and function, Mark was a hugely respected and much-liked individual, both within Telent and the wider telecoms and transport industries.

Mark also served on the company’s Board of Directors, to which he was appointed in September 2006. His appointment to CEO followed a series of successful appointments elsewhere in the business. He joined Marconi in November 1995 as Managing Director of the Services business, which he grew successfully.

In January 2001, Mark was appointed Managing Director of the Enterprise Networks business within the Europe, Middle East and Africa (EMEA) region. Here, he took the lead on strategy development and delivery for another new business.

In September 2002, Mark became successively Executive Vice President and Managing Director of the Group’s Value Added Services Division. This division addressed the needs of European Enterprise customers through a full portfolio of telecoms network outsourcing maintenance and new build turnkey projects.

Earlier in his career, Mark held several senior leadership roles in service-related businesses with London Underground.

It was with great sadness that Telent announced the death of Mark in September 2019. As both a remarkable CEO and a great friend, Mark’s legacy will continue to be felt by Telent and everyone who works there.
