It’s about the work – important work for amazing clients with dedicated and talented coworkers and partner firms. That’s what it’s all about and why I am here and enjoying it every day.”

Many people don’t realize the creative potential of a career in engineering. I have opportunities every day to synthesize new approaches from past experiences and develop whole new concepts from first-principle engineering concepts, all while advancing the objectives of our clients throughout the U.S. and beyond. AEI’s culture supports and encourages this creativity individually and within our project teams, and I consider myself lucky to be a part of it.

Geoff McMahon joined AEI in 1991 in Seattle and became a principal in 1995. He leads our Seattle office and provides support and leadership to AEI’s five West Coast offices.

Geoff has planned and led many large and complex projects throughout the U.S. and abroad, including research campuses for Amgen in the Northwest, a large oil company in Colorado, and an academic research campus in Saudi Arabia. He has also led large healthcare projects for the British Columbia Health Authority, Peace Health in Oregon, and the NIH in Maryland. He brings a strong understanding of the key issues involved in the master planning and design of these complex and technically driven facilities.

An ardent advocate for the use of sustainable design, Geoff played a leadership role in the execution of largest LEED Platinum research campus in the world — the KAUST campus in Saudi Arabia (over five million square feet). He also played an integral role in the design and deployment of one of the largest applications of chilled beams in the United States.
