Stirrett Johnsen, Inc. is a highly successful mechanical contractor founded in 1972 by Lee Stirrett and Brian Johnsen. The company began in the plan spec market competing statewide for Washington State K-12 education facilities, military, and industrial work at the local shipyard in Bremerton. Based in Silverdale, Washington, the firm quickly developed a reputation as an effective and quality-driven provider which soon led the founders to look at expanded markets and services.

In 1983, the company entered the design build market adding in-house mechanical engineering, design and coordination capabilities. One of the first landmark projects in the design build market was Bellevue Place in 1988. This 1,400,000 square-foot project was successfully designed and managed by SJI Mechanical Engineers Greg Swanson, P.E. and Rich Arper, P.E. with field supervision by Elgin Springgay, Larry Adams, Bruce Pearson, and Steve Sullivan.

In 2000, Steve Stirrett, Steve Sullivan, and Sean Sullivan executed a successful transition of corporate ownership. Since then, they have led an experienced staff with a combination of hard work, integrity, and passion for the trade. We compete vigorously in plan spec, design build, and design assist delivery methods across demanding markets such as healthcare, industrial, laboratory, military, and special projects.

In 2006, Greg Dehnert joined Stirrett Johnsen. Greg’s 30-years of experience providing exceptional project management, technical expertise and dedication was a perfect fit for our customer group and our culture of dedication at Stirrett Johnsen. Greg lead our streamlined Special Projects Division based out of Renton. This flexible high performance group dedicated to serving General Contractors and Owners with demanding project needs such as crucial outage or working in occupied spaces, bolstered Stirrett Johnsen and lead to the development of current key employees. In December of 2022 Greg retired with a legacy of outstanding performance and satisfied customers.
