Until the early 1950s, Pacific Northwest communities outside the larger metropolitan areas were passed over for natural gas service. In 1953, Pacific Northwest businessmen Lester Pettit, Spencer Clark, and Stewart Matthews formed Cascade Natural Gas Corporation to serve these communities with clean, affordable natural gas.In those early days, the founders faced many financial, engineering and operational challenges as they strived to expand service and enhance their operations. The company grew steadily to become one of the fastest growing natural gas utilities in the nation.Today, Cascade serves more than 294,000 customers in 96 communities – 68 of which are in Washington and 28 in Oregon. Cascade’s service areas are concentrated in western and central Washington and central and eastern Oregon.Cascade serves a diverse territory covering more than 32,000 square miles and 700 highway miles from one end of the system to the other. Interstate pipelines transmit Cascade’s natural gas from production areas in the Rocky Mountains and western Canada.Customers are served from three operational regions: Northwest – Bellingham, Mt. Vernon, Oak Harbor/Anacortes, the Kitsap Peninsula, the Grays Harbor area and Kelso/Longview Central – Sunnyside, Wenatchee/Moses Lake, Tri-Cities, Walla Walla and Yakima areas. Southern – Bend and surrounding communities, Ontario, Baker City and the Pendleton/Hermiston areas.Throughout our service areas, our mission is to be an integral part of the community with a firm commitment to being there when you need us. Through our friendly and dedicated employees and the services we provide, we hope you’ll find we are In the Community to Serve.Cascade is a subsidiary of MDU Resources Group, Inc., a multidimensional natural resources enterprise traded on the New York Stock Exchange as “MDU.” For more information about MDU Resources, visit the company’s website at
