John Dahlman, Superintendent



Superintendent John Dahlman has been in the industry for over 30 years. He began his career as a residential construction carpentry apprentice in 1978, doing rough and finish carpentry. He also spent time managing a restaurant in Mukilteo before his time in the construction field. So why construction all these years? “I’d rather build them, than work in them – and there is no ‘typical day’!” Here at Sierra, John’s portfolio is filled with office, public works, retail, mixed use and the occasional industrial project. Most recently, his projects included Blue Origin, Carmax Lynnwood, and Sierra’s own new headquarters.

Kyle Eldred, Project Manager



Project Manager Kyle Eldred has a portfolio filled with tilt-ups and concrete-focused projects. A Central Washington University graduate, Kyle always had his sights on the construction industry. “I was a Lincoln log kid, and it grew from there. I enjoy the ever changing challenges. No day is ever the same.”  In his time here at Sierra, Kyle’s projects have included mega-warehouses such as Amazon Troutdale and Stryker Business Center’s Amazon BFI4. “When I took my first 5 steps into the old Woodinville office I was told “You’re heading to Kent”. When I got to the jobsite my jaw hit the ground when I saw how massive the site was. That site was Amazon’s BFI4 – Project Wulf.”

Dawn Searles, Payroll



Dawn has been in Sierra’s accounting department for over 15 years. She found her niche in construction accounting after working for a flying school at Paine Field, an insurance company and a hospital. “The HR person at Sierra got me in touch with Nancy and fifteen years later here I am!” Her first jobsite visit was one of Sierra’s largest projects to date in Kent.  “The size of the project was enormous and so impressive. Seeing all the hard work the crew put in to make it be another quality project was impressive.”

What did you do for work before Sierra? During high school I worked for a flying school at Paine Field.  After college I worked for a large insurance company that was in the UDistrict and then went to work at a hospital in Everett for a while.  I finally found my niche with construction accounting.
