Seth Stapleton


Associate Principal

Everyday challenges excite Seth – a creative, determined, and efficient structural engineer. Whether it’s design or construction, he is always solving problems and coming up with new ideas.

For Seth, one of the biggest fringe benefits of being a structural engineer is touring a building he designed after construction. Seth enjoys being involved in a project from design through construction, and reveling in everyone’s hard work who helped make it a success.

Seth has more than 17 years of experience providing structural engineering services. He has expertise in design through all phases of a project, from initial building investigations and concept designs to completion of construction. Seth’s project experience includes both new buildings and numerous seismic upgrade, investigation, and building improvement projects. His practice areas include education, mixed-use residential, office, parking garage, and historic renovation.
