The senior management change follows Iain Thomson’s decision to step back after 10 years while remaining with the firm as chairman.
Suzan has been with Gratte Brothers for 20 years, and was instrumental in developing the firm’s off-site strategy.
Thomson said: “Remi and I have worked together over the last five years to manage this transition, it is with great confidence that I hand over the reins to a leader with such a positive and forward-looking vision for the company.”
David Gratte, managing director of Gratte Brothers Group said, “On behalf of the Gratte Brothers Group board, I would firstly like to thank Iain for the dedication and loyalty he has shown to the business as MD over the past 10 years.
“Gratte Brothers Ltd is the business it is today because of his vision and leadership and we are therefore delighted that he will remain as chairman.
“As Remi takes over leadership of Gratte Brothers, he does so with the full support of the Group and I have no doubt that he will continue to drive the business forward.
“Remi has more than proven his ability to lead during this transition and brings with him a unique blend of technical knowledge, approachability as well as a progressive and positive vision for the future.”
