Hamm & Phillips Service Company was founded in Ringwood, Oklahoma in 1966. It was originally called "Harold Hamm Tank Truck Service" and the company consisted of one Bobtail Ford truck.
Since 1966 the company's growth has been constant and steady. Growth continued through the oil "bust" in the 1980's, mainly because of a sound conservative business practice, and the growth continues. Hamm & Phillips services Oklahoma, Texas Panhandle, SW Kansas, and the tri-state area of North and South Dakota and Montana. – less–ZoomInfo
