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.

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?

Sean Royal

Project Engineer

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.
