Our Story
Integrating Design with Engineering
After 15 years of experience in residential structural design, Andrew Gahan, PE founded Upstate Engineering, Inc. in a home office in Mountlake Terrace, Washington. Since then, the firm has grown into a dedicated office space and expanded its team to include in-house designers, CAD drafters, permit coordinators, and additional engineers.
At Upstate Engineering, we bridge the gap between inspired residential design and efficient, buildable structure. Through clear documentation and responsive communication, we help eliminate uncertainty and keep projects progressing smoothly from concept to construction.
