Eastern Region Sales Manager

I am a mechanical engineer with 30 years of plant, sales and service experience. I have been on both sides of the desk and can relate with you when issues arise in the plant. You can trust that I won’t recommend a product unless I know that it will do the job for you.

Directeur des ventes de la région de l’est

J’ai un diplôme en génie mécanique avec 30 ans d’expérience dans les usines, les ventes, et le service. J’ai été de chaque côté du bureau et je comprends lorsque des problèmes font surface dans l’usine, l’importance que l’on doit y apporter. Vous pouvez être sûr que je ne recommanderai pas un produit à moins que je sache qu’il convient à votre application.
