Bennett, who joins after one year at Adding Value, has taken on the role of account director to assist the wider growth of TTA and to help the agency, which predominantly works with pharmaceutical clients, to develop into new market sectors.
Bennett said: "I felt that it was time to move on from Adding Value and I saw an opportunity for something new. I enjoy motivating a team and there was a slight gap for that at TTA.
"We are potentially looking to expand the team if there are any gaps but the focus is on nurturing the talent we already have."Adding Value strategy director Chris Clarke announced that he will leave his post at the end of the year after 12 months at the agency to focus on his business Purple Dog Solutions.
