For over three decades, AGC has relied on an experienced leadership team, responsible governance and multidisciplinary expertise to support the most demanding infrastructure projects in Africa.
AGC's governance rests on a Chairman and CEO, an Authorised Officer and a General Management team, supported by a General Control department, an IT department and a panel of Legal and Technical Advisors. Three directorates then carry out the company's activities.

He specialises in the financial and economic analysis of infrastructure projects, public-private partnership financing, corporate restructuring, bank guarantee management and taxation, with particular expertise in issues specific to water and electricity utilities. He is also well versed in public, private and PPP procurement.
