Meet Our Leadership

Jerry Pyatt

Jerry Pyatt is proud to be a second-generation Doe Run employee and to spend his entire career with the company.

Today, Jerry serves as CEO until he retires in December 2021.

The ability to motivate positive change within Doe Run and the industry defines Jerry’s 43-year career at Doe Run.

“Leading the development of our breakthrough hydrometallurgical metal production technology is a highlight of my career. We’re determined to bring this technology to the industry. It will provide increased value to the industry and Doe Run, and, most importantly, enable us to deliver on our environmental goals.”

Jose V. Hansen

Vice President – Sales and Marketing

“Every day represents a new opportunity to see how we can align our resources and actions with what is taking place in the global marketplace for the benefit of our company and our employees.”

One of Jose’s greatest challenges was managing the transition from selling primary metals as our core business to becoming a global mineral concentrates business when we closed the last U.S. primary smelting operation. His team worked hard to make this transition as smooth as possible for customers and the company.
