Cassie Withrow

Executive Administrator+Administrative Services Manager

Excellent customer service comes naturally to Cassie, who approaches every task with a can-do attitude. As Executive Administrator, she enjoys working with people that encourage her and test her limits but allow her to have fun along the way. She manages her time—and many others’—with extraordinary ease and keeps things running like a well-oiled machine. Outside the office, you’ll find Cassie hiking, exploring the city, and when the sun comes out, boating on Lake Washington—all with her husband and pups by her side.

Andrew Ellis

Design Manager

AIA, Assoc. DBIA™

Andrew spent 14 years immersed in his original calling: Architecture. He found that the most enjoyable and rewarding moments occurred while collaborating with builders. Deciding to blend two passions together—design and construction—Andrew now leverages robust VDC tools to better understand, communicate, and help execute a project’s design intent. Simply put, he constructs the building virtually to iron out any wrinkles before it’s built in the field. Outside the office, Andrew can’t get enough of the mountains. The numbers speak for themselves. He’s made his way to the summit of Mount Rainier via 16 different routes!
