Allen & Overy today announced that Andrew Ballheimer has decided to step down as Global Managing Partner at the end of his current term on 30 April 2020 and retire from the firm, after 35 years in private practice including 15 years in senior management roles at A&O.

Andrew was elected to his current role in May 2016 and before that was Global Co-Head of Corporate. During his tenure as Global Managing Partner (working alongside Global Senior Partner, Wim Dejonghe), the firm has grown strongly, with client revenue growing 26% and profit per equity partner 38% in the first three financial years. The current financial year's trading continues this trend of significant growth, driven by a strategy focusing on exceptional client service, an integrated network of more than 40 top tier offices around the world and industry leadership in innovation. 

The firm's leadership has also championed diversity and inclusion in all its forms, with A&O being recognised as one of the Top 50 Employers for Women in the UK by The Times/Business in the Community and the recipient of the Queen's Award for Enterprise for the promotion of social mobility.

Commenting on his decision to step down, Andrew said: "This has been an immensely difficult decision for me, as A&O has been my professional home for almost a lifetime and it has been a unique privilege to serve in my current role. I am happy that the firm is in such great financial shape and, as a result, after 35 years in private practice including 15 years in various senior leadership roles at A&O, I feel it is a good time to explore new challenges in the outside world, including in the wider community, before I am too old!"

Wim Dejonghe, Global Senior Partner said: "I have thoroughly enjoyed working with Andrew and I will be very sorry to see him go. I would like to thank him for his huge contribution to the firm, both as Global Managing Partner and in his previous roles."

Andrew joined the firm in 1987 and became partner in 1994.  He has had an award-winning legal career in mergers and acquisitions and capital markets. He has worked in London, Tokyo and New York, where he was Head of International Capital Markets. He was Managing Partner of the London Corporate Department from 2005 to 2010 and then Global Co-Head of Corporate from 2010 to 2016.
