The existing four-strong Board will be bolstered as Jane Falconer and Matt Blowers are promoted to chief human resources officer and chief operating officer for fit out respectively.

In addition to the promotions, Gordon Kew joins the business to head up the company’s UK construction business. Gordon Kew joined Interserve in 2009 after six years with Miller Construction.

Existing board member, Paul Weaver will become chief operating officer for ISG’s engineering services business, and continues to spearhead the company’s core focus on achieving optimal operational efficiency.

Paul Cossell, ISG’s CEO, said: “I’m delighted to welcome three new members to our existing four-strong board at ISG. Jane, Matt and Gordon all bring exceptional experience, expertise and insight to our leadership team at a time when our business is seeing its most consistent period of sustainable growth and strongest financial performance in our history.

“Our people are the key to our continued success and that’s why we have made it a strategic priority that human resources is represented at board level, and I’m thrilled that Jane has agreed to step up to this new, business critical role. As we look to attract the highest-calibre individuals that will drive our business forward, we are increasingly focused on accessing a global talent pool of the most capable people with the expertise to deliver major projects at the £100m scale and above internationally.

“The promotion of Matt Blowers to our board brings just recognition to one of our longest serving, operationally outstanding and admired colleagues, who brings the drive and passion to extend our global market-leading fit out capability to even greater levels of success.

“I’m also pleased to announce that experienced leader, Gordon Kew, has not only joined our business, but 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.”
