Our Mission

We build lasting relationships with our team, clients, and the community because of our dedication to service, commitment to quality, and deep resources and experience.

Our Vision

At Korsmo Construction, success is measured in decades. Behind every new project we build, there is over 70 years of knowledge, experience, and satisfied clients. Korsmo Construction has evolved with our clients, growing and changing to meet their needs.

Our vision is to be the most respected and sought-out general contractor and construction company because of our reputation for integrity, quality, service, partnership, and value to our customers.

Our History

Korsmo Construction is a second-generation, family-owned company that was founded in 1948 by four brothers: John, Gordon, Martin, and Paul Korsmo. Korsmo Brothers Construction quickly grew into a well-respected general contracting firm, performing work throughout western Washington.

In the mid-1970s, John Korsmo Construction, Inc. was formed as a sole proprietorship by John Korsmo, Sr. In 1985, John Korsmo, Jr. joined the company and served as the company’s president for over 30 years.

Today, Korsmo Construction is a solely owned corporation located in downtown Tacoma, Washington. While our company has grown significantly during the past half-century, our clients still count on the same personal and professional relationships that first made us a premier general contractor more than a generation ago.

With experienced employees, outstanding resources, and a commitment to innovation, we work diligently to create lasting relationships and achieve our clients’ goals.


Korsmo’s continued commitment to excellence has resulted in recognition for quality construction, safety, community partnership, and sustainability.
