Macomb County company named GM Supplier of the Year

-Posted on August 23, 2019


Cadillac Products Automotive Company (CPAC) was founded in 1942 when M.P. Williams set out to meet the urgent needs of the U.S. government during World War II. More than 75 years and four generations of family leadership later, the automotive supplier is thriving – having just been named a Supplier of the Year by General Motors. This is the second time the company, which produces exterior and interior acoustical parts and watershields, has received the award.

“We hold our suppliers to a high bar,” said Steve Kiefer, GM senior vice president, Global Purchasing and Supply Chain. “They went above and beyond to deliver the innovations and quality that will help us earn customers for life.”

GM awards the Supplier of the Year title to companies that exceed its expectations, create outstanding value and introduce innovations. This year, 133 companies from 15 different countries received the recognition.

“We are honored and humbled to be recognized along with all the great suppliers to General Motors,” said Jim Williams, marketing manager at Cadillac Products. “This is a true testament to our commitment to continuous improvement in all we do in the automotive space.”

CPAC, which has locations in Roseville, Troy, Rogers City and Schertz, Texas, celebrated its achievement at an event on August 2. Held outside the Roseville facility on a bright and sunny day, the afternoon featured tours, lunch, games and remarks from the company’s fourth generation leader, Mike Williams.






Macomb County Executive Mark A. Hackel also attended and addressed those gathered. He spoke on the longevity of Cadillac Products, which can be attributed to the company’s innovative production capabilities. For instance, its vertical integration and range of manufacturing processes can provide clients with a wide choice of material options and designs to meet their individual needs.  

Another reason for CPAC’s 75-year existence: its committed workforce of 225 individuals. Many employees have worked for the company for more than 20 years. Notably, one individual has a tenure of 51 years – an incredible feat for any worker or company. These numbers speak volumes about Cadillac Products and its family-oriented environment. But as Baby Boomers begin to retire, the company must look to attract and retain a new generation of talent. For that, the organization is turning to programs like FIRST Robotics, an initiative that inspires young people to be leaders and innovators by engaging them in programs that build science, engineering, technology and life skills. Through sponsorships and mentorships, CPAC is helping to create the workforce of the future. A workforce that will perhaps keep the company in business for another 75+ years.
