Stephen Hartley-Brewer worked extensively in the financial investment and consulting sectors before establishing The Negotiation Skills Group to provide high level negotiation skills training and advice on the planning and conduct of major negotiations.

In July 2015 his firm merged with Hartley-Brewer Negotiation Consultants and Stephen now runs the combined business. 

A highly effective trainer and an experienced consultant, he also has strong financial knowledge and skills which are particularly useful when working with clients in the financial services sector.

Stephen has worked with clients in sectors ranging from investment banking and private equity to mezzanine finance, law firms and business services.

After graduating with a First in Philosophy, Politics and Economics from Magdalen College, Oxford, he joined The Boston Consulting Group, one of the world’s top consulting firms, where he advised clients in sectors ranging from financial services to retail.

He then moved into finance.  While working at blue-chip private equity and hedge funds including BC Partners and TPG-Axon, his negotiation experience covered advisory mandates, financial covenants, distressed debt restructurings, private equity investments, take-privates and litigation.

Having enjoyed negotiating far more than staring at stock prices on a Bloomberg screen or crunching numbers in a spreadsheet, he retired from the markets to establish his own firm specialising in high level negotiation skills development.  In doing this he is drawing on a lifetime of lessons from watching and listening to his father Mike Hartley-Brewer who, until his retirement in 2010, was widely regarded as the world’s best trainer and consultant in the field of negotiation.

In his spare time Stephen enjoys playing in poker tournaments, scuba diving and skiing, and is an international level freediver.
