Last week, it was announced that Reynolds-MacKenzie had been purchased for an initial fee of £2.6m to become part of the Open Health venture (prweek.com/uk, 13 July).
It is Open Health's second acquisition since launching in January, following the purchase of healthcare advertising agency Lane Earl Cox in April.
In a PRWeek interview (3 March), Open Health founding partner David Rowley said he expected to make 'one or two acquisitions by the end of the year'.
Open Health co-founding partner Sandy Royden said the firm had fulfilled its primary ambition to secure expertise across all four comms disciplines - medical, brand, PR and market research.
She added that the firm would now turn its attention to growing the PR offering of the business 'organically,' but did not rule out further acquisitions.
Reynolds-MacKenzie MD Alison MacKenzie said there would be no changes to staff or existing services at the agency.
She added that, as part of the deal, provisions had been put in place to ensure the agency's culture would not disappear.
She said: 'We've seen acquisitions unfold in the sector and when a company is bought, the culture can often be lost. Throughout this process, we have ensured that the culture of the company is maintained.'
