sbchapinThe late S. B. Chapin established Willmar Electric Service Corp in 1920, an innovative man dedicated to progress and quality workmanship. His policy was simple and direct – make quality electrical installations for a reasonable price and treat everyone fairly. Although the modern world has become more complicated, those basic policies have remained unchanged.

Two of Sam’s sons, Elmo and Frank, joined the firm in 1946 and continued the tradition of quality service and up-to-date technology. The firm was incorporated in 1948, becoming Willmar Electric Service Inc.

John Chapin, Elmo’s son, joined the firm in 1968 and became a prime force in the further growth and development of the company. 

Since John’s grandfather founded Willmar Electric Service. in April of 1920, we have focused on giving the customer the best possible service. Dealing with customers openly is more than a way of doing business; it is a part of our corporate culture that has been present since the first day. We have experience working on all types of construction projects and can meet all of your electrical needs. When customers come to us with unique and special problems, we are proud to be able to serve them with flexible and qualified experience that we have been acquiring since 1920.

David and Justin Chapin, John’s sons, purchased the firm in 2007 and are the fourth generation of the family to manage the firm. David and Justin are very thankful for the chance to continue the family’s legacy of providing our customers with a quality product and serving our employees.


As we continue to grow and expand, our future success is strongly dependent on the people we hire. Willmar Electric Service is a people-oriented, profit-motivated company. Without profit, our continued effort to be people-oriented would be severely curtailed. As we grow and prosper, we want you to grow and prosper with us. At Willmar Electric Service our brand promise is to deliver projects on time, in an organized manner by being approachable to everybody involved in the project.
