West Bottoms 12th St New — Kansas City, MO — Reliance Paper Co.

Kansas City, Our Town


David Rielley and wife Berenice Rielley established Reliance Paper in 1959 in Kansas City, Missouri. Reliance was originally a fine-paper business, but the Rielley's quickly found a niche in corrugated boxes (brown paper, if you will). David and Berenice's son, Richard Rielley, worked at Reliance from a very early age, unloading from the rail boxcars that used to run behind the building. Richard owned the business from 1989-2021, passing the outfit on to his son, Seán.


We pride ourselves on excellent customer service, nimble turnarounds, and competitive prices. Reliance Paper Co. has been home in the historic core of the West Bottoms since 1967. On September 26, 2022, the Missouri State Historic Preservation Office listed our building in the National Register of Historic Places under Criterion A: Commerce. We are very proud to be a small part of Kansas City history and we enjoy sharing that history with all those we meet.
