Philip Hollister is retiring from JF Finnegan after 50 years with the Sheffield building group.
Mr Hollister joined the Ecclesall Road firm from school in 1963, working his way up to commercial director before taking over from Philip Ryan as chairman in 2010.
He leaves at the end of the month, after a year during which the group boosted turnover by 35 per cent to £34.2 million and completed a series of major projects.
During his time with Finnegan, Mr Hollister was involved in a number of landmark projects, including Sheffield Parkway Business Park, Butcher Works, the award-winning Charles St Q-Park ‘Cheesegrater’ and the innovative, highly sustainable Sheffield City College.
Mr Hollister said; “Having spent my entire working life at JF Finnegan, it hasn’t been an easy decision to step down but we have been preparing the business for some time.
“I’m incredibly proud of everything that JF Finnegan has achieved and whilst my time as chairman coincided with one of the most challenging economic climates on record, our recent results demonstrate how well we have weathered the storm.”
