Our History

;
A Tradition for Over 70 Years
Western Pump was founded in 1948 by Walter Reed, Troy Reese, and Mac Daniels as a fueling service station maintenance company. In 1974, the company was sold to two owners of R. H. Alexander Co., a Los Angeles-based petroleum equipment distributor and service provider. At that time, the business was focused on fuel station equipment distribution and fuel tank testing. Herb Chapin managed the San Diego operation until 1978 when William Biery Sr. took over and assumed ownership.
In 1988, Dennis and Jan Rethmeier acquired Western Pump and further developed the business to include construction, vehicle service equipment, and compliance testing. In 2013, Dennis and Jan retired, and their son, Ryan Rethmeier, became president.
Today, Western Pump is a full-service gas station construction and maintenance company for fueling and transportation infrastructure facilities. We are the only integrated construction, service, maintenance, compliance, and equipment distribution company in Southern California. Western Pump remains a family-owned-and-operated business, with strong traditional family values interwoven throughout the fabric of the company.
