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.

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.

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