Our History

We have been doing business for over 70 years.

Western Pump was founded in 1948 as a service station maintenance company. The company changed ownership twice before 1988, at which point 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 provider for fueling and transportation infrastructure facilities. Western Pump remains a family-owned and -operated business with strong, traditional family values interwoven throughout the fabric of the company.
