Hennessey

People, operations, leadership and risk are usually connected. Hennessey brings senior judgement across those boundaries to establish what is really happening and what needs to change.
We support owners, boards and managers across the UK and international markets, combining central direction with sensitivity to local operating, cultural and regulatory requirements.
