Our History

Few companies have the range of experience and capabilities available at O&A Manufacturing.


O&A Manufacturing Inc. was established in 1978 as O&A Tool Specialties, a small Tool and Die shop operating in Madison, Wisconsin.  Our business centered on designing and building tools along with stamping dies for our customers.


In 1987, O&A moved to our current headquarters in Verona, Wisconsin.  Over the years our business focus expanded and in 2003 our name changed to O&A Manufacturing Inc. to include the wide range of capabilities and experiences.


In 2020, after several years of growth and expansions, O&A added a second facility in Brooklyn, Wisconsin to meet the needs of our customers. O&A continues our history of over 40 years of supplying quality products for Manufacturers throughout the Midwest.
