A case study of our work: Dr. Martens

Where we started
Dr. Martens were looking to identify a Global Health & Safety Manager to define, shape and lead the implementation of a global safety strategy that provides a clear standard and framework. The role was primarily tasked with working collaboratively with all areas of the business to educate, influence and support, to raise the bar on safety.

How we helped
We undertook a methodical global search to identify a strong shortlist of candidates. The successful candidate had a proven track record of driving health and safety performance in a multi-national environment in both global investment banking and property, meaning they were able to seamlessly transition into the role and hit the ground running.
