McGarahan was most recently interim director of comms for Bradford & Bingley, overseeing its nationalisation last autumn.
He has now joined the UK's largest waste management company as interim group corporate comms director. It is the first time the group has brought in a PRO at a global level.
He was brought in to handle media for the rights issue last week, which is expected to propel the company into the FTSE250 next month.
But he has also been asked to create a reputation management strategy for the group that will encompass investor relations, media relations, CSR, public affairs, internal comms and overall group branding. He will also ‘make recommendations on a resource structure to support the strategy' and oversee retained agency Tulcan Communications, which replaced Citigate last year.
Currently individual marketing and comms managers are based in the firm's four operating countries - UK, Canada, Belgium and the Netherlands, but no-one oversees comms at a group level.
McGarahan reports into CEO Tom Drury, who has been in position for the last 18 months.
McGarahan is a veteran of turnaround roles. He advised Equitable Life after its near-collapse in 2000 and more recently rejigged AXA's comms structure.
