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.”

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.

Steven Bradshaw

Senior Project Engineer

Steven was on the move for much of his childhood. Born in Germany and raised in Texas, Colorado, Wyoming, and Washington, Steven learned to embrace new environments early on. He now thrives on meeting new people, leveraging the diversity among various backgrounds, and working together to find solutions. Steven earned a BS in Construction Management from Washington State University and now looks for opportunities to mentor college and high school students interested in a similar educational and career path. When the sun breaks through, he hops on his bike, works in the yard, plays football, and tries to improve his golf game.

Andrew Ellis

Senior Design Engineer

RA, LEED AP BD+C, Associate 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!

Kevin Eng

Senior Preconstruction Manager

LEED AP BD+C, Associate DBIA™

Kevin praises the aspect of GLY’s culture that provides a variety of paths for diverse abilities and personalities to flourish. Hired on as a Project Engineer, Kevin’s exceptional preconstruction talent quickly developed. As Sr. Preconstruction Manager today, his practical knowledge of construction methods, materials, resources and LEED criteria, and penchant for estimating varied and complex projects is benefitting all of our project teams.

Mike Martel

Project Manager

Associate DBIA™, LEED AP BD+C

Mike joined GLY in 2013 as a Project Engineer and has steadily increased his responsibilities, becoming a Project Manager in 2020. He holds a BS in Construction Management from the University of Washington, where he later returned to earn a Commercial Real Estate Certificate. That’s just one example of Mike’s passion for continuous learning—and sharing with his teammates. He’s especially versed in the latest developments in 3D modeling and navigating the complex processes of advanced BIM visualization. After a long week at work, Mike burns off steam by running, cycling, and skiing.

David Martinez

Superintendent

David’s craft roots run deep, stemming from his start as a self-employed residential framer. From that foundation, he built a resume of over 30 years’ experience working with a wide range of materials and methods in a variety of market sectors – mastering the role of Superintendent along the way. After all these years, he still enjoys heading to the jobsite, troubleshooting with the team, and mentoring the next generation of field leaders. His devotion to construction is exceeded only by his love for family … and softball, which he plans on playing until he exceeds the maximum age limit.
