Bernard Tronel embarked upon his professional life at Deloitte in 1972.
In 1990 a private equity fund asked him to temporarily take over the General Management of Machines Serdi, a machine tools manufacturer experiencing financial difficulties, until a permanent manager could be appointed. The manager never arrived! The fund decided to stop supporting the company. He fought for four years to put the company back on its feet and then sell it.
In 1995 the group Lex Services plc called upon him to straighten out a French subsidiary engaged in the longterm hiring of capital goods. It was to take him three years to put this company back on track. These experiences led him to specialize in the management of companies in difficulties. Since 2005 he has run the Essensys office in France.
In 2008 he took part in establishing the French Interim Management Association, and was its first president. He is a member of the French Institute of Directors.
