Former MD of technology agency Abacus PR Sally Costerton has joined
Hill and Knowlton as a director in its technology division. When Abacus
merged with its sister agency Arrow PR this March to form Kaizo PR,
Costerton became client services director. Costerton will report
directly to H&K technology managing director Giles Fraser and will help
run the division, the largest at H&K’s London offices, with 20 people
reporting to her. Her role is a newly-created position.
