Philip Malliet

CEO & President

With 30 years of success in leadership roles within a variety of industries, Phil joined Hayes as President and CEO in 2014. An innovative and creative international business leader, Phil is an agent of change. “Change is the new normal and those who proactively drive change will be the winners.”   Phil leads his teams with a proactive sense of urgency because he knows customers always have alternatives. He is a leader who encourages questioning the status quo, while requiring accountability to achieve operational efficiency, consistent financial performance, and profitable growth.   Throughout his career, Phil has proven the ability to attract and mentor highly productive teams. He has led them in the execution of aggressive, multi-faceted strategic initiatives to deliver the company mission. “Strategy deployment is the process that gives life to a strategic plan—it is the differentiator that separates a great company from the rest.”   Phil earned his BS in Mechanical Engineering from Marquette University and an MBA also from Marquette. He resides in Colgate, Wis., is married to wife Karen and has two children. Outside of Hayes,  he enjoys golfing with his wife—who regularly scores better than he does. To blow off steam, he looks forward to a good trail ride in the summer or winter and is excited to pilot one of the many Hayes equipped mountain bikes or snowmobiles in its demo fleet.

Rod Fostner


Bean counter, numbers cruncher, money dude…in his more than 30 years of diverse financial and management experience, Rod’s heard just about every clever (and not so clever) term for financial officer. But he’s quick to tell you that his experience is more than financial. He’s also been in operations management, product development, sales, marketing and distribution strategy. “I feel the best financial officers have a fully rounded perspective. I know our business from all aspects. So, when I make a decision or give advice, it usually reflects what’s best for the entire company, not necessarily just the bottom line.” Rod holds a bachelor’s degree in accounting and finance from the University of Wisconsin and is also a CPA. In his free time, he likes to sharpen the right side of his brain with art and cultural outings. Not surprising given his penchant for being an all-around guy.
