Melanie Cochrun

Director of Marketing+Communications

CPSM

A healthy dose of serendipity led Melanie from the Peace Corps third world to the A/E/C integrated world, where she discovered a love for working with the people behind the concrete. Nearly 20 years later, she is contributing and receiving ideas and inspiration for marketing, communicating, and developing business as the Director of Marketing + Communications at GLY! A self-described thinker, linker, and obstacle shrinker, Melanie likes to approach her work with these three questions: Who is our audience? What do they need? How can we reach them and develop trust?

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.

René Ansdell

Senior Project Engineer

LEED Green Associate

René’s background in construction management and architecture provide her with a fluency in both languages, adding value to each of her projects through this diverse perspective and the ability to see the bigger picture. She is highly detail-oriented, an eager learner, and always emphasizes the importance of staying in close communication. After work, you can find René hiking, painting or drawing, or playing softball and flag football.

Bryan Haakenson

Principal+Operations

LEED Green Associate

A Northwest native, Bryan embodies GLY’s collaborative, community-centered approach. As a Principal of the firm and our Operations Leader, he oversees GLY’s people resources, processes, and field labor delivery, working closely with salaried and craft team members, human resources, safety, and the Tool + Equipment Yard to ensure operational excellence across the company.

In years prior, Bryan specialized in delivering projects within occupied senior living and other sensitive environments, and continues to provide strategic support to teams working in those market sectors. Today, he also leads GLY’s Sustainability Advocacy Group, helping to identify and implement strategies that reduce the firm’s operational carbon footprint.

Beyond the workplace, Bryan is deeply involved with the Washington State chapter of the Alzheimer’s Association, where he has served in a variety of board roles for over a decade. He and his family love taking advantage of the Pacific Northwest outdoors — boating in the summer and skiing in the winter.

Reed McNulty

Superintendent

Ever wonder if a Superintendent gets tired of scheduling? Just ask Reed! After more than 37 years in the industry, he still loves solving each new puzzle. A GLY veteran with a deep resume, he’s done it all from high-tech office buildings to heavy site civil work—mentoring up-and-coming field supervisors along the way. Outside the jobsite, he works on his collection of muscle cars and unwinds in the outdoors with fishing and hunting.

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.

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.
