“Don knows the organization from the inside out, understands the technology, and knows how important quality, on-time delivery, and customer trust are. After the consolidation of U.S. companies, we need leadership that stays close to the operations, the team, and the market. I believe he will bring energy, decisiveness, and a highly practical perspective to the continued development of our presence in North America,” said Sławomir Woźniak, CEO of the SECO/WARWICK Group.

SECO/WARWICK USA remains a key part of the Group’s global structure. The U.S. organization is responsible for serving one of the world’s most demanding industrial markets while developing capabilities in vacuum technologies, service, local manufacturing, and the implementation of solutions from the Group’s portfolio.

Piotr Zawistowski Strengthens the Supervisory Board

Piotr Zawistowski, who has managed SECO/WARWICK’s U.S. organization to date, is joining the Supervisory Board of the SECO/WARWICK Group. In his new role, he will support the Group’s Management Board in sales and the strategic development of the Group on the North American market. He will also help strengthen the connection of knowledge, resources, technological assets and competencies between SECO/WARWICK USA in Meadville and Retech in Buffalo. This is particularly important in the context of the Group’s continued development of its American pillar, which encompasses both heat treatment technologies and advanced vacuum metallurgy solutions.

“I congratulate Don on taking on his new role and wish him every success. At the same time, I would like to thank the entire team for their years of intensive work, especially for their commitment to the consolidation process and building a stronger organization. By joining the Supervisory Board, I will remain close to the Group’s U.S. business and support the continued growth of the SECO/WARWICK global brand,” commented Piotr Zawistowski.

Piotr Zawistowski has been continuously associated with the SECO/WARWICK Group since 2005. He graduated from the Częstochowa University of Technology. For years, he has been recognized as an industry expert in the North American heat treatment market, as well as a regular speaker and thought leader in vacuum and atmosphere furnace technologies. He holds both Polish and U.S. citizenship.

A New Phase After Consolidation

The leadership change at SECO/WARWICK USA is a continuation of the process initiated by the consolidation of the Group’s U.S. companies. The merger of the SVT and SWC structures helped organize the company, simplify processes, increase cost efficiency, and strengthen the clarity of the SECO/WARWICK brand in the North American market.

The new management model is intended to accelerate the use of synergies between engineering, manufacturing and service competencies in the U.S. An additional element of this strategy is a stronger connection between the capabilities of Meadville and Buffalo—that is, SECO/WARWICK USA and Retech—while preserving the independence and specialization of both organizations.

First of all, I would like to thank everyone for their trust. I have worked within the SECO/WARWICK Group for 18 years, and I am proud to lead its American pillar. This is a great honor for me, but above all, a commitment to the team, the customers, and the entire Group. I am taking over the organization at a very important moment—after consolidation, with a clear brand, a larger scale of operations, and real momentum. Our goal is to continue strengthening SECO/WARWICK’s position in the U.S., develop operational capabilities, and consistently build value for customers,” says Donald Marteeny, the new Managing Director of SECO/WARWICK USA.

SECO/WARWICK has been present in the U.S. market for decades, and the United States remains one of the Group’s key areas of growth.
