Global Segment Leader
"Recently, I was invited to Washington University’s Olin Business School to present Watlow’s global experience to the Professional MBA Program. It is very exciting to see one of the world's leading academic organizations reach out to us for our global business expertise."
"The Rotational Program originally drew me to Watlow. The program allows individuals to spend the first two years after graduation in multiple positions and learning all aspects of manufacturing from quoting and designing new products to making and delivering existing parts. It really gives an in-depth look at manufacturing and helps you to understand where your interests and skills lie for a better job fit in the end."
