2026 GLY Construction, Inc.

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.

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.

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.”

Trevor Lunde

Director of Virtual Design+Construction

Associate DBIA™

Trevor is an industry innovator with over 22 years of experience devoted to creating synergy between architectural design and technical construction. Trevor leads strategic business planning for the company’s Virtual Design and Construction [VDC] and technology efforts and provides companywide training on GLY delivery philosophy and VDC process. Having been both a project architect and a construction manager, he identifies valuable opportunities for coordination and collaboration amongst designers, engineers, and tradespeople. Trevor respects each discipline’s individual process and expertise while ensuring constructability. Trevor’s downtime is spent playing with his kids or fishing.

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.

Amereo Forks

General Foreman

As a decisive person with a positive and open-minded attitude, Amereo enjoys the everyday team collaboration. As a General Foreman, Amereo makes good job-site morale and cohesive team environment a priority. He finds joy in seeing the building team bring a client’s vision to life from start to finish. At home, Amereo enjoys tackling small projects and spending time with his family. Fun fact: Amereo is a twin!

Jon Friedrichsen

Project Executive

HCC

Jon attributes his appreciation of craft and hard work to working as a carpenter for a Spokane-based general contractor while earning a BS in Construction Management from Washington State University. Since joining GLY in 1999, he’s honed his expertise as a healthcare and high-tech office project manager and team builder. When he’s not piecing together complex logistics plans, you’ll find Jon cheering on the Seattle Sounders or casting a line. If he could talk his wife into selling everything and living in a trailer down by the river, he’d be there already.
