Mary Wareing




Summary Bio

Mary has 20 years’ experience in performance and management consulting across a number of key sectors in the public and private sectors. She has deep expertise in value creation, problem solving, and building and leading strong teams. She has been with Partners in Performance since June 2022 and is Partner, UK.

Before joining Partners in Performance, Mary was an independent consultant for 11 years, collaborating with a wide range of clients to define and deliver high impact business strategies to maximise value. Prior to this, she was Programme Director with Arla Foods, Head of Transformation with Sheffield City Council, and Engagement Manager with McKinsey and Company.

Mary believes in staying focused on the key things that really matter for a particular engagement and which help her confirm she’s having maximum impact for her clients and teams. She does this by being a relentless prioritiser and by encouraging others to cut through what they ‘could do’ and spotlighting what they ‘should do’. She maintains that this way, everyone is clear they are making progress on delivering results.
