That’s why I aim to be visible, both through site visits and within our offices. I take part in safety interactions and communicate regularly with our teams through our newsletters, videos and face-to-face updates.
“Our people are our business, and within G&S we have an array of knowledgeable, talented and experienced employees. Our success as a business is attributed to their determination, passion and commitment.”

“I am committed to making G&S a successful, sustainable and enjoyable company to work for, and some of my proudest moments at G&S have been witnessing the achievements of our people. Whether it’s seeing someone who started as an apprentice gain their trade or someone in a junior role progress through to management, it’s what makes my job rewarding and worthwhile.”
