Established by Neal Proos in Grand Rapids, Michigan in 1919 originally as a manufacturer of casket hardware and cookie die stamps, Proos Manufacturing evolved into metal stampings and created a strong partnership with the automotive industry. In recent years as the auto market has declined, we’ve turned to our successful sheet metal fabrication as a way to diversify into new markets. In 2011, sheet metal operations were expanded and a new facility was leased to open our sister company, Proos Fabrication. By focusing on our core competencies at each location, Proos has become a leading provider of manufacturing and engineering solutions for the automotive, industrial, furniture, medical, defense and energy application industries.


What Makes Us Different

We work to provide solutions for our customers. Through this philosophy and by concentrating on our areas of expertise, it naturally led the company to growth and stability. It is important to us that we do not follow where markets are going – we follow where customers don’t have the answers they need. Through this process Proos has become diversified in the services we can provide – from engineering and manufacturing support to product development, design and problem resolution. As our Vision Statement says: “We will be our customer’s preferred supplier by always doing what is right, what is best for the customer, and accomplishing what others have said cannot be done.“ Engineers at Proos have worked on the shop floor and understand that design has to be brought to manufacturability while keeping costs down and quality up. At Proos, we know that our engineers are the difference between our company and our competitors!

Our CEO: Amy Proos

As the 3rd generation – and first woman – CEO and owner of her family’s nearly 100-year-old company, Amy is leading the charge as Proos diversifies, prospers and grows. Amy began her career at Proos as a college student in the summer of 1987, working on the shop floor producing automobile parts. She learned a great deal about how multiple parts come together to make the finished product and how their production affects the company and everyone involved. By the end of the summer, Amy was hooked – she returned to school in the fall and changed her major from veterinary medicine to production and inventory management. Amy continued working at Proos during her school breaks and while she knows her formal education was important during this time, she credits the Proos employees for teaching her the most. After graduation Amy worked in various capacities throughout Proos before completing her purchase of the company in 2010 and becoming CEO.

Amy prides herself on having an open line of communication with her employees and focusing on the needs of her customers to consistently provide solutions with ingenuity. Among many accolades, in 2011 Amy won the Enterprising Women of the Year Award and in 2012 Proos was named one of the “Michigan 50 Companies to Watch”. In June 2013, Amy Proos was named a winner of the Ernst & Young Entrepreneur Of The Year® 2013 Award in Michigan & Northwest Ohio.

I feel that it’s important to tell the entire story. Although people may not like what I’m saying, they’ll always appreciate the truth. Being candid has earned me the trust and respect of my 83 employees and our valued customers.
