Mr. Wright Found of ASCO standing beside an excavator bucket.

In 1959, Bill Wright moved his family back to Texas after spending a successful 15-year career with Humble Oil and Refining Company and a year in Connecticut with parent company Standard Oil. The family briefly lived in Tyler, Texas, before a move to Lubbock, Mr. Wright and his wife’s hometown. 

Mr. Wright had returned to the town where he had grown up playing football on sandlots and in dirt streets under the flickering light of gas streetlights. He and his band of friends would grow up to play football for Lubbock High School and bring home the first-ever Lubbock State Football Championship. They were the 1939 Cinderella Team. Their coach died three games into the season. They dedicated the rest of the season to Coach Nick. They weren’t too big or fast, but they had more heart than anyone they played they didn’t lose another game! Mr. Wright went on to play for The University of Oklahoma. Mr. Wright joined as an officer in the United States Naval Construction Battalions, better known as the Navy Seabees, and was deployed to the Philippines and China. 

In early 1960, Mr. Wright joined his brother-in-law, Kenneth Pharr, at Associated Supply Company, INC. an irrigation pump, engine, and Army surplus store. Shortly after, the pair was presented with an opportunity to be a dealer for Towmotor Lift Trucks. By 1965, Caterpillar Tractor Company acquired Towmotor Lifts Trucks.

The Family Behind ASCO: The Wright Family

Founder Bill Wright had his sons join him in the family business in 1973 and 1975. In Lubbock, W.B. (Brax) Wright is the CEO, and J.S. (Steve) Wright, in Amarillo, is the company’s President. Paula Wright Key, Bill’s daughter and treasurer for ASCO, is also proud to be part of the family operation.

Paula’s son, Chase Key, joined ASCO in 2009 and was the first of the third generation to return to ASCO. Courtney Wright Vanderham, Steve’s daughter, joined the company in 2010, and John Wright, Brax’s son, joined the company in early 2013.

Today, ASCO is West Texas’s oldest material handling and construction equipment dealership under continuous single-family ownership.
