EDESSA is an acronym for Engineering, Design and Environmental Services S.A. We are a leading engineering and environmental firm who has conducted numerous consultancy, design, supervision and contracting projects around the world.

EDESSA was setup in November 2000 by taking over the activities of Dames & Moore, one of the largest US environmental engineering firms, in Lebanon.
