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 Sign 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.
