Sean recently joined GLY after completing two internships which gave him firsthand experience on high-stakes projects in the construction industry. With a degree in Construction Engineering Technology, he brings a solid foundation of technical knowledge and hands-on experience to his role as Project Engineer. In this capacity, he handles key responsibilities in trade management, overseeing work scopes, ensuring quality and safety compliance, and supporting project scheduling and budgeting. A Kirkland native, Sean enjoys spending his free time on Lake Washington, hitting the golf course, or experimenting with new recipes in the kitchen.

LEED AP

Project teams benefit from Spencer’s hit-the-ground-running attitude and determination in finding the best solutions for the task at hand. His natural ability to facilitate a collaborative environment by asking questions and bouncing ideas off team members often results in creative solutions for the tasks at hand. He enjoys applying many of the same concepts to parenting, as he raises three young children with his wife Taylor.

Dennis Sizemore

Cement Mason Superintendent

Dennis is the go-to guy on anything and everything concrete. At age 15, he poured and finished driveways, patios, and shop slabs. When he started at GLY at 18, he was the youngest journeyman in his union. Today, he's a concrete master who oversees projects up to one million square feet. His favorite aspect of the job is the constant change of scenery since he's not on one single project for an extensive amount of time. While concrete is a big part of Dennis’s life, he makes plenty of room for his kids, fishing, hiking, and visiting Kauai, his happy place.

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!

Melanie Cochrun

Director of Marketing+Communications

CPSM

A healthy dose of serendipity led Melanie from the Peace Corps third world to the A/E/C integrated world, where she discovered a love for working with the people behind the concrete. Nearly 20 years later, she is contributing and receiving ideas and inspiration for marketing, communicating, and developing business as the Director of Marketing + Communications at GLY! A self-described thinker, linker, and obstacle shrinker, Melanie likes to approach her work with these three questions: Who is our audience? What do they need? How can we reach them and develop trust?
