From the original gold leaf storefront signs to today's modern business callouts, Doyle Signs has built its name on quality sign manufacturing with a professional maintenance guarantee. Doyle Signs was founded in 1916 by William J. Doyle as a sign painting enterprise serving Chicago area real estate firms and local merchants. The company expanded to a full-service sign contractor under the direction of Howard J. Doyle from 1955-1977. Relocating to Addison Illinois in 1961, Doyle Signs grew from 8,000 sq. ft. to its now 36,000 sq. ft. of specialized manufacturing space. Doyle Signs has remained family owned and operated, proudly serving many of its original customers, while extending its quality service and expertise not only to the Midwest, but throughout the United States.
