A S Klein Engineering, PLLC is a professional engineering firm founded in 2013 after a need was identified in the western United States for code consultation and advocacy.  Headquartered in the beautiful Tri-Cities in eastern WA, we are proud to share our geography with offices of many of the world’s leading research and engineering firms.

Originally planning to exclusively offer design review and code consulting services for high-hazard occupancies, A S Klein Engineering, PLLC quickly earned an equally-respected reputation as energy experts.  Projects on which we have successfully consulted range in size from small tenant improvements to $8B semiconductor plants.
