Career highlights

During a career spanning more than 23 years, I have held the position of Managing Director within two successful M&E companies. I joined Realys in 2013 to strategically develop and lead the company’s engineering service offering. During this period we have built a world-class engineering team that has successfully developed innovative strategic solutions for a wide variety of blue chip clients by means of disrupting the traditional engineering model ethos.

The highlight to date is the strategic creation of our bespoke Engineering Initiative Lifecycle modelling tool. This innovative platform informs the client on ‘best value’ investment strategies across the P&L life cycle of their M&E portfolio, taking into account both initial CAPEX investment as well as OPEX expenditure throughout the life of their investment. This model outlines not only the financial benefits but also the environmental ones, by means of calculating the energy and carbon reduction from the traditional benchmark.

Why Realys?

Realys is collaborative, innovative and positively disruptive. I firmly believe that the company is on track to become the strategic market leader in the building services industry.
