John Tessem

PE, SE

Principal, Seattle

Structural engineering is a form of expression using logical thinking and organizational skills. What can make it rewarding is being part of something bigger – working with great clients and design teams toward a common goal. Structural engineers contribute to civilization and society by designing safe and appropriate design for shelter, but the expertise can go way beyond just the basics."


Having more than 27 years of industry experience, John applies simplicity and efficiency in all of his engineering ideas and takes great satisfaction in real world application of math and science to build structures. Since joining DCI in 2005, he has successfully designed and managed a wide variety of significant projects offering engineering solutions for architects and other clients. John has met their vision and economic goals for commercial projects ranging from public, private, national and international buildings. Common building types that come his way include parking structures, high-rise residential, hotels, and office towers, convention centers, hospitals, medical office buildings, aircraft hangars, and retail.

If you weren’t an engineer, what would you be?
I’m not sure. There are lots of things I’d like to do, but I’m not sure I could earn a living!

What is your favorite place, building, or built environment in Seattle?
Safeco Field. I love the baseball season and watching the Mariners on a sunny afternoon.
