Says John Lamprinakos: “I’m not the expert of the best practices here, the people doing the work every day are. I intend to spend a great deal of time with them, as well as our sales team and our dealers, to learn all I can as we build a path toward our future success, and crush every job.” Photo courtesy of Screen Machine

John Lamprinakos, who spent four decades at Worthington Steel, joined Screen Machine and Diamond Z as president and CEO.

Lamprinakos previously led sales and production on a variety of steel products at Worthington Steel. Now, he will help guide Screen Machine and Diamond Z as they produce high-volume, mobile crushing, screening, grinding and chipping machines.

“When I toured the facilities here and saw the pride and dedication of the employees of both companies, and realized the potential both have for tremendous growth in the future, I was hooked,” Lamprinakos says.

Lamprinakos is a native of Pittsburgh, Pennsylvania. He attended Duke University and earned a bachelor’s degree in economics.

Screen Machine acquired Diamond Z of Caldwell, Idaho, earlier this year. Diamond Z is a producer of grinding and chipping machinery. The Crane Group of Columbus, Ohio, owns Screen Machine and Diamond Z.

“The culture at Screen Machine and Diamond Z, as well as The Crane Group, is all about respect, communication, generosity, loyalty and family,” Lamprinakos says. “Those are exactly what we held as tenets of our company at Worthington Industries. My role here will be to build upon those principles as we continue to produce machines that meet and exceed the expectations of our customers.”
