Triwonder Signs was founded in 1989 by Richard Croydon. We are medium sized family business with our roots in the OOH advertising business. Initially we started building, selling, installing and maintaining three sided displays and have remained at the forefront of the evolving OOH industry ever since. Triwonder has pushed innovation from the early days of the Trilateral signs, to Scrollers & huge Lightbox’s. More recently Triwonder has moved to DOOH (digital out of home) displays which we launched in 2005. DOOH is our fastest growing sector. We continue to be one of the main facilitators for the OOH advertising industry.
