The agency is looking to further strengthen its team in 2016, with a number of additional appointments on the horizon.
Lucie Hammerton, talent manager at TRO, said: "We have had a very busy start to the year and this is reflected in our recruitment activity.
"We are currently looking to fill a number of diverse roles across our UK offices – including account handlers, an internal marketing manager and a workshop technician. We are seeking bright, passionate individuals to help drive our business forward in 2016."
