Bennett's role will be to extend Anthem's brand point management approach among existing clients and also in the wider marketplace.
Barry Seal, UK managing director at Anthem Worldwide, said: "With her excellent strategic thinking and strong brand skills, Alex is well placed to help us consolidate our successes to date and help us expand through growth of our existing clients and also contributing to new business development."
Bennett has worked at a senior level at several design consultancies including Cowan Design, Parker Williams, Turner Duckworth and Design Bridge.
During that time, she focused on a number of major brands including Coca-Cola, Co-op, Heinz, Sainsbury's and Superdrug.
Bennett said: "This is a very exciting time to be joining Anthem Worldwide, following the group's recent acquisition of DJPA and with its ambitious plans for the future.
"Its approach provides clients with the means to maximise the impact of its messaging wherever shoppers and brands interact -- at home, on the go, in store or on the shelf.
"It's a very compelling proposition to take to clients when every penny counts."
