Christian Jehanno

Design Office Manager, Saint-Herblain Branch

Working at SEIMAF has given me the opportunity to learn about different sectors and broaden my knowledge. As a project manager, this has enabled me to satisfy my
appetite for variety by coordinating mechanical,
conveying, general installation and other projects.
I currently manage the Saint-Herblain office, and I won’t get tired of my job any time soon.
