Long-serving Matheson stalwart Bill Kroll, chairman and CEO for the last nine years, has assumed the role of executive chairman of the Board of Directors, with former president and COO Scott Kallman taking up the reins as president and CEO.

The moves were effective January 2, 2013, with Kroll reflecting on the opportunity for closer coordination with parent company TNSC and taking the group to the next level.

Under his leadership for close to a decade, Matheson more than tripled its revenues. Kroll will continue to lead the company’s board and corporate auditing functions, and will continue to serve as a member of the board of directors for TNSC.

He said of the change in role, “This leadership transition will allow me to focus on capitalizing on growth opportunities and synergies afforded by close coordination with TNSC. I am looking forward to working with newly appointed TNSC Chairman, Hiroshi Taguchi, to help move the TNSC Group forward on the global stage.”

Meanwhile Kallman, in his expanded role, will continue to lead Matheson’s operations and customer-facing division and also assumes responsibility for corporate administration, human resources, legal services, business development, information technology, R&D, marketing, and finance.

In Kallman, Kroll believes the right person is in place to take the company forward.

“Scott Kallman joined Matheson in 2005, running the industrial side of the business, and since then, he has made several significant improvements in the areas of safety, quality, and customer focus, serving recently as chief operating officer.”

“Scott is the right person to take Matheson to the next level as we seek to advance the company as a world leader in the industrial, specialty, and electronics market segments,” he concluded.
