About PSCO Kieffer

Leaders in sign products and branding for over 60 years.

Company Overview

PSCO Kieffer has a long history in the sign industry, evolving over the years as a leading fabricator of quality signs. Our roots date to 1959, when Kieffer & Co. was established in Sheboygan, WI.

In April 2022, the Sheboygan facility was acquired by PSCO Global Group and rebranded as PSCO Kieffer. We are proud to be a privately held, family-owned business that understands the sign industry and values making the best decisions for our customers.
