Son to one of the first developers of the modern gravity separator circa 1897 he helped pave the way for Oliver in the industry. After him, the company was run for 40 years by Oliver’s grandson Geoff O. Burney, and is currently guided by Oliver’s great grandson, Brian Burney.

Oliver W. Steele founded Oliver Manufacturing in 1930. It’s a family-owned business currently run by the 3rd generation. From the beginning, Oliver implemented strategic principles to make and deliver high-quality products. Our mission is to leverage technology to infuse durability and efficacy into our solutions.
