Management team


Over the past 20 years at Arum we’ve built up a strong team with extensive expertise across various areas. Not only are our practitioners experienced consultants, but they’re in a unique position to be able to understand our clients’ particular business challenges because many have previously held similar responsibilities client-side.

The range of experience – from senior thought leaders with an average of 30 years’ experience to consultants with less than 10 years’ experience – means that we can offer teams tailored to clients’ needs.

As well as outstanding subject matter experts, the Arum team possess a range of other skills and experience that will add significant value to your organisation.  These include multi-lingual capability and experience of working in over 50 countries.
