About Us
Siefken & Sons Construction Inc. was founded by Bill R. & Reta Siefken in 1975, along with their five sons, Richard, Scott, Jeff, Brian & Bill Jr. Beginning as a residential contractor, Siefken & Sons has evolved into the well-respected, high quality commercial contractor that it is today. The company works within both the public & private sectors, maintaining close relationships with their clients to achieve their goals on every project. We recognize that success in the construction industry is defined not only by the construction process itself, but also the complete satisfaction and positive relationship built with our clients
Currently, Siefken & Sons Construction Inc. is operated by President Jeffrey Siefken and his two sons Jeremy Siefken & Jake Siefken. As project managers, field superintendents and estimators, both Jeremy & Jake supervise the day-to-day construction activities, including coordinating construction schedules, managing subcontractors, and coordination with the owner & architect involved, ensuring that each project is managed efficiently and effectively in a timely matter.
