Here are some testimonials from our best alumni.

“Rejean is a great system administrator who knows his network inside-out. He’s always quick to fix any problem that we had and he did the job well. In addition to his sysadmin work, we have had the chance to collaborate on several research projects and Rejean has shown that he can come up with novel solutions quickly. Overall, he is a sharp individual who is really good at what he does.” July 20, 2006 Tien Bui, Ph.D., Assistant Professor, Universite du Quebec a Chicoutimi

“I know Réjean for almost 3 years now and he is one of the best system administrators I have seen. He resolves any problems that he faces in a timely manner. He has deep understanding of the systems he manages and he acquires new knowlege very fast. Réjean is a definate asset to any company. He has many years of experience backed up with a masters degree in computer science.” July 20, 2006 Bill Pontikakis, Ph.D. student and Researcher in cutting edge technology, Ecole Polytechnique de Montreal worked directly with Réjean at Polytechnique

Je ne peux oublier de remercier M. Rejean Lepage et Mme Ghyslaine Ethier Carrier, des personnes importantes pour moi et sans aucun doute pour le GRM, qui ont toujours eu une écoute attentive et des gestes attentionnés à mon égard.
