Kelley Williamson Company was established in 1926 by entrepreneurs Walter Williamson and his partner, Nate Kelley.

Kelley’s Market Connection

Kelley’s Market, a cornerstone in local convenience stores, is an establishment by Kelley Williamson Company. Established in 1926 by visionaries Walter Williamson and Nate Kelley, we serve as an ExxonMobil distributor, managing fuel stations and convenience stores across Northern Illinois and Southern Wisconsin.

As the proud parent company of Kelley’s Markets, Kelley Williamson Co manages a network of nearly 50 state-of-the-art convenience stores and fuel centers across Northern Illinois and Southern Wisconsin.

Founded on principles of quality, timely service, and expert product knowledge, KW Oil originated as a modest gasoline and lubricant distributor.
