Corporate

Expedia Seattle HQ Campus

Expedia

Seattle, WA

“Seneca Group has been a valued partner for Expedia going back many, many years. They were key in helping us identify a location for our future campus. It’s 41 acres on reclaimed land and they kept us going through that process over 5+ years of development and delivery. Along the way, we also managed to include a complex little gem like The Prow into the process. I would absolutely love to work with them again.”

– Josh Khanna, Director, Global Workplace Services – Expedia Group
