Matt Alvarado

Senior Design Engineer

Rick Thompson

General Foreman

As a professional in the industry for more than 50 years, Rick shares advice that has served him well in life: “Love what you do and treat everyone the way you want to be treated.” As a General Foreman at GLY, he finds great satisfaction in working with clients and seeing what the team has accomplished at the end of each day. Building is Rick’s lifelong passion, and it extends into his hobbies as well. You can usually find him in his home shop, where he builds exotic furniture, restores old motorcycles, and crafts his own fishing lures and setups. He also spends time preparing his gear for his favorite seasons—spring and fall—when he takes his fishing boat out on the Puget Sound or heads into the outdoors to enjoy hunting.

Tyler Tonkin

President+CEO

Since joining GLY in 1998, Tyler has played a pivotal role in shaping the company’s culture and project delivery excellence. Now serving as President and CEO, he brings a collaborative spirit, deep technical expertise, and a strategic mindset to every facet of the business. Tyler’s leadership has guided some of GLY’s most complex and transformative projects—from integrated hospital expansions to urban highrise developments. His commitment to client advocacy and team empowerment continues to inspire innovation and elevate performance across the organization.

Cassie Withrow

Executive Administrator+Administrative Services Manager

Excellent customer service comes naturally to Cassie, who approaches every task with a can-do attitude. As Executive Administrator, she enjoys working with people that encourage her and test her limits but allow her to have fun along the way. She manages her time—and many others’—with extraordinary ease and keeps things running like a well-oiled machine. Outside the office, you’ll find Cassie hiking, exploring the city, and when the sun comes out, boating on Lake Washington—all with her husband and pups by her side.

Anita Phonexayphova

Senior Design Engineer

LEED AP

Anita began her career in architecture and has since migrated to the construction world where she enjoys collaborating with design teams and subcontractors to work through constructability issues while achieving design intent. She employs advanced technologies throughout a project’s lifecycle from early design estimates to virtual project handover and closeout. Anita also supports our project teams by coordinating MEP and running clash detection.

Laura Soma

Sustainability Manager

LEED AP BD+C, LFA

It’s no wonder that Laura’s passion is helping people find their potential. She’s worked hard to creatively forge her own career path and achieve her goals. She is active in a number of industry groups and peer networks focused on green building and leads GLY’s internal sustainability efforts. 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.
