LEED Green Associate

In the short time Benji has been with GLY, he has already distinguished himself as a hardworking and reliable team player who is continuously learning all he can. He is often the first to arrive and last to leave—by choice!—as he truly enjoys his work and is always willing to take on new challenges and push himself to keep learning and growing. Benji can also often be found biking and enjoying the outdoors.

Cassie Withrow

Executive Administrator

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.
