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!

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.

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!

Michelle Connor

Business Equity Specialist

Since joining GLY in 2019 as a Project Coordinator, Michelle steadily assumed more and more responsibilities, eventually combining her personal interest in DEI with our clients' goals for trade equity. Naturally she signed up for our corporate DEI Committee, where she continues to make a valuable impact. As our Business Equity Specialist, Michelle provides project team guidance and support to achieve MWSBE and apprenticeship utilization goals, develops community engagement initiatives, and maintains ongoing community and industry involvement to deepen relationships within the public sector and ensure current knowledge of local, state, and federal regulation for adhering to contract requirements. When she’s not busy chasing her turbo-charged toddler, she’s dreaming up new book club picks that will either dazzle her coworkers or make them question her taste in literature.
