From their website:
Imperial Western Products started as a small corporation in Coachella, Ca in 1966, with just a single location and only 9 employees until the mid eighties. The company originally traded commodities in the agricultural markets. Since 1966 Imperial Western Products has grown by leaps and bounds to become a very successful, broadly diversified corporation, always at the forefront of our industries. Lee Trawick, founder of Imperial Western Products, was always dedicated to producing quality products and providing excellent service to its customers. This same passion can still be found at Imperial Western Products, from the desk of the corporate executive in Coachella California to the blue collar laborer in Buckeye Arizona, always making quality and customer service their top priority. The expansion of the current multimillion dollar company includes twenty-eight divisions over eight locations and five production facilities throughout the Southwest.
