“Ian will provide the overarching, dedicated focus needed to guide it through a fast-changing commercial landscape. In his role, both as an ExCo member and head of the branches, he brings the depth of leadership, management and client facing experienced required. I am delighted that he has chosen Charles Stanley for the next stage of his career and to welcome him to the team.”
