The Manchester-born 36-year-old was most recently senior vice-president of Text 100 in San Francisco. He had been with Text for more than a decade, having joined in London in 1995.
‘The decision to leave came as I felt that after running Text 100's San Francisco office I needed to move up a level professionally and I was keen to run an entire company,' he said.
He replaces Greg Spector, who was CEO at B&O for six years. Spector is now working for an Oslo-based telecoms start-up called Rebtel, although he remains based in the US.
B&O is a Hill & Knowlton company founded in 1985. Clients include Hitachi Business Systems, Computer Associates and telecommunications company Verizon.
The agency employs around 75 staff worldwide, with offices in Boston, Austin (Texas) and London, as well as San Francisco. It closed down its bureau in Atlanta late last year.
The ten-strong UK office was established in 2002 (PRWeek, 19 July 2002) and is headed by MD Simon Glazer, who was appointed in January 2005.
Text 100 was unable to comment on who had replaced Hampton as PRWeek went to press.
