Mark was named executive vice president of SDI and president and chief operating officer for flat rolled-steels and ferrous resources in 2007.
Mark is in charge of flat-rolled steel products, metals recycling, ferrous technologies, and mining and minerals. As head of this business group, he’s responsible for the following current operations and functions: the Flat Roll Division (including the light-gauge galvanizing facility at Jeffersonville, Indiana), Iron Dynamics, Shredded Products LLC, Mesabi Nugget, and corporate Ferrous Resources and Logistics. His responsibilities also include the development of certain other planned projects, including direct iron reduction and additional scrap-processing operations.
Beginning in 1998, Mark managed the company's Flat Roll Division at Butler, Indiana, including the hot mill, cold mill, and coating facilities. Under Mark’s leadership, the Flat Roll Division experienced exceptional growth, including upgrading of the facility to include a paint line, expanding shipping capabilities, and increasing the mill's production capacity to approach 3 million tons per year.
One of the co-founders of Steel Dynamics, Mark is a major shareholder and has served on the board of directors since the inception of the company. He earned a bachelor's degree with honors in metallurgy from the University of Surrey, England.
From 1981 to 1985, Mark served as chief metallurgist for Nucor Corporation's Darlington, South Carolina, division. He was then charged with developing the world's first commercially viable thin-slab-casting process as the manager of that project at Nucor's Hazelett facility. The process began to produce a commercially acceptable product in 1987.
Also in 1987, Nucor entered into an agreement with SMS to build the world's first thin-slab minimill in Crawfordsville, Indiana. Mark's responsibilities there included the design, construction, staffing, and operation of the melting and casting facility. Mark left Nucor in 1993 to co-found SDI with colleagues Keith Busse and Dick Teets. |
