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!

Today Garth is a hard-working Superintendent who enjoys building challenges across sectors, from housing to commercial construction. Garth takes a very thorough, caring approach to getting things done on his projects, and enjoys the outdoor life in his spare time—especially riding dirt bikes, camping or doing anything on or near the water.
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].
