I engaged Leading Resolutions to lead a complex and at times turbulent transformation programme, and they added value right from the get-go, bringing control, stability and drive to move the programme forward. They were a great partner to work with, consistently demonstrating an ability to understand our needs and bring in the right capability at the right time.Marie Harrison
