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.

On his current project, the University District Station Building, Tim and team are building a 13-story office tower atop Sound Transit's light rail station at NE 45th St and Brooklyn Ave. A former member of the UW track team, Tim traded in his running shoes for hiking boots, and enjoys exploring PNW trails with his wife and two sons.

Ben Hamm

Project Executive

Assoc. DBIA™

Ben honed his exceptional leadership skills during his first calling as a high school English teacher, coach, and director of admissions. Patient, communicative, and adaptable to change, the AEC industry scored big when he decided to switch gears and earn another degree, this time in Civil Engineering. Progressing from Project Engineer to Project Executive at GLY, he continues to leverage his diverse background—listening intently to clients and teammates prior to making critical decisions. Hailing from Western New York, where cows outnumber residents, Ben remains a loyal Buffalo sports fan—Go Sabres and Bills!

Josh Lewis

Senior Project Manager

Organized, decisive, and driven, Josh approaches every project with a clear understanding of the client and company’s needs. His favorite part about his position is that no two projects are ever alike, as he is a person who enjoys overcoming the hurdles of a project from start to finish. Quite fitting to his problem–solving nature, he enjoys classic games that require lots of thought and strategy, from chess to backgammon to cribbage. Outside of work he also stays busy coaching youth baseball, softball, basketball, and his son’s Little League All-Star Team, who made it to the State Championship in 2024!

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].

Her background as a Project Manager allows her to connect with clients and project teams to drive sustainability project goals while keeping budget and schedule at the forefront. Laura brings her love of responsible practices [and infectious good spirits] to every project.
