The Hayes Leadership Team



Philip Malliet, CEO & President


With 30 years of success in leadership roles within various 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’s 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’s 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 attended Marquette University and earned his Bachelor of Science in Mechanical Engineering, then later earned an MBA there. He resides in Southeastern Wisconsin with his wife Karen and 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.
