2026 GLY Construction, Inc.

Caitlin Eckert

Project Engineer

LEED Green Associate

Bringing a personable and bubbly attitude to project teams, Caitlin has no trouble connecting with any kind of client, owner, or architect. She finds the variability of a Project Engineer’s day-to-day to be fascinating and especially values her time on site which gives her a visual understanding of her work and the project as a whole. Driven by the same sense of curiosity and adventure outside of work, Caitlin stays very active with a variety of hobbies. When she is not trail running, skiing, or climbing, you’ll find her sewing winter adventure hats and hanging out with friends.

Danielle Sessler

Senior Project Manager

Associate DBIA™

Construction was always part of the plan for Northwest native Danielle, having grown up in a family that owned a contracting business. She took a few detours first, earning a BFA in Metalsmithing and Art History from Central Washington University and working as a Senior Estimator focused on honing her preconstruction services skills. When she landed at GLY in 2013, we quickly recognized her background would be perfect for Design-Build projects. Outside of work, Danielle enjoys hiking, bouldering, climbing—and collecting “odd things that most people scratch their heads over.”

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.

Luke McArthur

Assistant Superintendent

Bryce Engen

MEP+CX Manager

LEED AP BD+C, BCXA CCP

Bryce is a mechanical systems and commissioning expert and a self-described Swiss army knife. He gets involved during preconstruction assisting with MEP scopes of work. During construction, he becomes hyper focused on QA/QC processes and procedures. On the back end of the job he develops closeout and inspection schedules and plans for startup and commissioning. He is a passionate alumnus of Washington State University, where he studied Construction Management, and minored in Business. His wife, two kids, two dogs, and Macaw parrot keep life busy but fun. Their latest achievement? Building a house together!

Joe Sahlin

Superintendent

Joe embodies a team player, believing that “a successful project is not achieved by a sole individual.” He consistently acts as the glue that adheres the various entities coordinating a project to one another, supporting the successful delivery of a high-quality product. Joe’s perspective that client expectations are a baseline to surpass, is a product of his competitive spirit.

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.

Isaias Villa Galvan

Safety Director

CSP, CHST

Before entering construction safety, Isaias began his career as a wildland firefighter, where he developed a calm, confident approach to risk management. That experience made his transition into safety and construction management a natural progression. He has since proven himself a strong leader, capable of guiding teams of safety professionals and fostering a culture rooted in accountability and safe work practices, making him the perfect fit for Safety Director at GLY. Outside of work, Isaias stays active through Brazilian Jiu Jitsu, strength training, running, hiking, and golfing, and he enjoys spending downtime reading. Despite calling himself the world’s worst swimmer, swimming remains a favorite hobby [an unexpected passion that perfectly reflects his willingness to embrace any challenges he is faced with].
