Our Road to Becoming a Leading Manufacturing Investment Firm

Demmer Manufacturing is proud to have a rich history of service, investment, and philanthropy. We can trace our roots back to 1951, when John Demmer founded the Demmer Corporation in Lansing, Michigan. From humble beginnings, the Demmer Corporation grew rapidly, building trust with the community and clients worldwide. John’s son Bill Demmer carried that legacy forward to make Demmer Manufacturing what it is today—a leading privately owned investment firm with a portfolio of precision machining and metal fabrication companies that serve clients across the globe.
