Blaine, MN – February 17, 2020 – Arrowhead Engineered Products (AEP) President and Chief Executive Officer (CEO) Jim Wisnoski announced today that he will step down from the role effective April 1, 2020. Jim will remain as an advisor to the Board of Directors and to the newly appointed CEO.

“I am delighted that John will become our company’s next CEO,” said Wisnoski. “He has demonstrated exceptional leadership in his short tenure leading the operations of our company, and he brings the same vision and values to lead AEP into the future. I am also excited about this next chapter in my life to spend more time with my family, while remaining connected as an advisor to the company that I have spent the last 14 years building.”

“I am thrilled to take on the leadership of AEP and continue to drive performance for all our stakeholders. I was drawn to the business because of the company values, Jim’s vision and the strategic opportunities we have in front of us. I did not expect the warm culture and such a talented workforce. This is going to be fun!” said Mosunic.
