Gordon Kew parted company with Interserve in a management shake-up last September after nearly ten years at the company.
He started at ISG this month as Chief Operating Officer for UK Construction.
Kew joins the ISG board which has also been strengthened with the promotion of Jane Falconer and Matt Blowers to Chief Human Resources Officer and Chief Operating Officer for Fit Out respectively.
ISG is predicting 2018 was a record year and annual results will be announced this Spring.
Paul Cossell, ISG’s CEO, said: “Gordon Kew will play a pivotal role on the board setting the strategic direction of our strongly performing UK Construction business.
“Gordon has an exceptional industry pedigree and will be a major asset to our business.”
