Gilles Thieffry, the founder of GTLaw®, has over 25 year’s experience, primarily in the City of London where he was a partner in two leading international firms (see Profile). Gilles can properly be regarded as one of Europe’s leading specialists in commodity finance, structured finance and derivatives.
As a small, highly focused, practice without the infrastructure and overheads of a major law firm GTLaw ® is able to offer a value added service at highly cost-effective rates. The firm’s philosophy is based on personal service. Clients instructing GTLaw ® will not find that their matter is dealt with by someone they have never met.
