About our Signage Company

Trusted sign manufacturer and turn-key partner for hundreds of brands.

Company Overview

PSCO Kieffer has a long history as a signage company in the Midwest, evolving over the years as a leading fabricator of quality signs. Our roots date back to 1959 when Kieffer & Co. was established in Sheboygan, WI as a local sign manufacturer of customer business signs.

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

PSCO Kieffer focuses on making custom business signs in our 115,000-square-foot state-of-the-art manufacturing facility. We are a turn-key signage company that specializes in custom business signs. Our team ensures our products are delivered consistently with excellence and repeatable best practices utilizing quality materials and methods.

Located in the Midwest, our signage company plays a key role geographically for PSCO Global Group. We are part of the six sign manufacturing facilities throughout the US and collaborate to provide the best solution based on the overall scope of work.
