Kristine Walz, Senior Project Manager

Kristine started her career at Sierra in 2005. She new from a young age that should would end up in construction. “I started drawing floor plans in kindergarten. When other kids were trying to draw stick figures, I was trying to draw my house’s elevation. I would get so mad at Lincoln Logs because you could never build a proper shed roof.” After graduating from the University of Oregon in Architecture, she began at Sierra as a Project Engineer. Her first projects included big box retail stores like Kohl’s and Walmart. Now a Senior Project Manager, she has managed large scale industrial projects including Amazon Troutdale, and is currently wrapping up Bridge Point I-5 in Portland.

What is one thing you couldn’t live without. Besides the obvious (my children, my husband, etc.) I would have to say audio books. 

If you could have one superpower, what would it be? Big cat whisperer

What is the best book you have ever read? My favorite book of all time is The Blue Sword by Robin McKinley. I read it for the first time when I was 14, and I read it at least once a year. 

Tell us something that might surprise us about you? I’m a crazy cat lady. It’s not the number, it’s the mindset. 

What is your favorite color? Pink. The hotter the better. 

Scott Mathis, Superintendent

Scott is a Superintendent here at Sierra. He came to Sierra in 1995 as a Carpenter, and has since worked his way to Superintendent. Over the years he has worked on projects of all types, but his favorite project was the Sammamish Library. “I love building and being able to see what was accomplished at the end of the day. There’s no such thing as a typical day, especially in the multifamily world.”


What did you do for work before Sierra? Dairy farming and cabinet making.


How do you spend your weekends? Farming, remodeling and spending time with my family.


Least favorite fruit or vegetable? I can’t stand mushrooms (why would anyone knowingly eat fungus). I pick the little ones from cream of mushroom soup out of casseroles.


If you could have one superpower, what would it be? The power to heal


What is your dream vacation? Ireland

Now as a Project Manager for Sierra, over the past five years Sam’s portfolio includes multiple concrete tilt-up projects and their associated tenant improvements, including Prologis Park Tacoma and Portside 55. If you could do any job for just one day, what would it be? General Manager of the Seahawks. What is your favorite pastime? Playing soccer. Favorite book? I read The Boys in the Boat recently and highly recommend it. If you weren’t in construction, what would you be doing for your career? Accounting or Engineering. Something heavily math based. What is something you can’t resist? Anything with chocolate in it.

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. Tell us something that may surprise us about you. I like driving anywhere in the world, on the left hand side. If you weren’t in construction, what would you be doing? Painting coconuts on a beach in Hawaii If you could do another job for just one day, what would it be? Race car driver! What is the best book you have ever read? Pillars of the Earth If you could have one superpower, what would it be? I’d like to fly to work to avoid the traffic….

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.” How do you spend your weekends? Carpentry, fishing or golf! Tell us something that might surprise us about you. I used to play in a classic rock band. I played keys and sang. “Don’t stop…believin’!” What is your ideal vacation? Adventuring the back countries of Hawaii or any tropical place If you could have one superpower, what would it be? Fly!
