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.

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.”

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].
