World-Class Manufacturing Facilities

At Guy & O’Neill, we believe that a product is only as good as the factory that creates it. Guy & O’Neill prides itself on maintaining clean, world-class manufacturing facilities. Our product development, production facilities, and warehouses are all located in Wisconsin and Minnesota.

Most of our operations take place in Fredonia, WI. Fredonia is nestled among rolling hills alongside the Milwaukee River. Located 30 miles north of metropolitan Milwaukee, the village is a thriving community that maintains its own industrial park without losing its rural charm. Find out more about Fredonia on the Village Website.
