Sylvain BéllangerDirector of the Syndicat du Collective I in Boucherville
We asked Trahan and Mercille to replace all our sodium luminaires with LED lights. The advices they provided us from the beginning to the end of the project was very useful and very appreciated. The knowledge and professionalism of the consultants and technicians with whom we have collaborated have always lived up to our expectations. I would not hesitate for a moment to mandate Trahan and Mercille again for our future electrical projects and I recommend them without hesitation.
