Founded in 1991 by MD Hilary Meacham, 20-strong Focus remains independent, with clients including Cadbury Trebor Bassett.
Focus posted £1.5m turnover and £1m fee income for the year ended May 2006. It acquired interiors and design specialist Silk PR three years ago (PRWeek, 11 June 2003).
Strawberry director Bryony Johnson led a management buyout of the agency in 1998. It has around ten staff with clients such as Wonderbra and Britney Spears's perfume, Curious.
Neither agency would comment on the acquisition.
