TRO chief executive Keith O’Loughlin has left the marketing experiential agency after more than 30 years.

A statement read: “Keith was one of the original shareholders of the business and was pivotal in the sale of TRO to global marketing group Omnicom in 2008, which led to the agency’s expansion. He has now decided to leave TRO to go on to his next chapter. We owe Keith an enormous debt of gratitude and he leaves with our thanks and best wishes for the future.”

O’Loughlin’s replacement is yet to be announced.
