Washington, D.C., September 30, 2016 – On the 10th anniversary of the Sandy Trowbridge Award, the National Association of Manufacturers (NAM) has awarded Dudek & Bock Spring Manufacturing Company of Chicago, Ill., with the honor. The Trowbridge Award honors an NAM member company that demonstrates exemplary leadership in serving its community or state and is a leading example of the nation’s manufacturers and businesses.

“Manufacturers in the United States strengthen our communities in more ways than just making great products and providing high-paying jobs,” said NAM President and CEO Jay Timmons. “Dudek & Bock and its employees are showing every day the positive difference manufacturers make in their communities, by participating in service, leadership or volunteerism activities, helping to excite the next generation of manufacturers. All manufacturers—and all Americans—should follow the company’s example.”

Dudek & Bock began as a family business in Chicago in 1946 and is celebrating its 70th anniversary this year. It is a world-class manufacturer of springs, wire forms and light metal stampings and is recognized for its broad community engagement. Dudek & Bock has a dedication for manufacturing training and education programs to encourage the next generation of manufacturers. Partnering with local high schools and community colleges, creating a middle school– and high school–aged robotics program with a local library and offering hands-on site visits and community career counseling, Dudek & Bock is shaping its community for the better.

“For our company and our employees, giving back to the community is not only part of our mission, but also our passion,” said Dudek & Bock President John Dudek. “We work with high schools and colleges around the Chicago area to foster and build today’s youth into manufacturing’s future. We are honored to receive this award.”
